The goal of portfolio management is to come up with the best investment plan tailored for you, considering your risk tolerance, time horizon and financial goals. Given its importance, no wonder there are no shortage of commercial portfolio management apps and stock market monitoring software, each touting various sophisticated portfolio performance tracking and reporting capabilities. + +For those of you Linux aficionados who are looking for a **good open-source portfolio management tool** to manage and track your stock portfolio on Linux, I would highly recommend a Java-based portfolio manager called [JStock][1]. If you are not a big Java fan, you might be turned off by the fact that JStock runs on a heavyweight JVM. At the same time I am sure many people will appreciate the fact that JStock is instantly accessible on every Linux platform with JRE installed. No hoops to jump through to make it work on your Linux environment. + +The day is gone when "open-source" means "cheap" or "subpar". Considering that JStock is just a one-man job, JStock is impressively packed with many useful features as a portfolio management tool, and all that credit goes to Yan Cheng Cheok! For example, JStock supports price monitoring via watchlists, multiple portfolios, custom/built-in stock indicators and scanners, support for 27 different stock markets and cross-platform cloud backup/restore. JStock is available on multiple platforms (Linux, OS X, Android and Windows), and you can save and restore your JStock portfolios seamlessly across different platforms via cloud backup/restore. + +Sounds pretty neat, huh? Now I am going to show you how to install and use JStock in more detail. + +### Install JStock on Linux ### + +Since JStock is written in Java, you must [install JRE][2] to run it.

In each watchlist, you can add multiple stocks you are interested in. Then add your alert thresholds under "Fall Below" and "Rise Above" columns, which correspond to minimum and maximum stock prices you want to set, respectively. + +![](https://c2.staticflickr.com/2/1588/23795349969_37f4b0f23c_c.jpg) + +For example, if you set minimum/maximum prices of AAPL stock to $102 and $115.50, you will be alerted via desktop notifications if the stock price goes below $102 or moves higher than $115.50 at any time. + +You can also enable email alert option, so that you will instead receive email notifications for such price events. To enable email alerts, go to "Options" menu. Under "Alert" tab, turn on "Send message to email(s)" box, and enter your Gmail account. Once you go through Gmail authorization steps, JStock will start sending email alerts to that Gmail account (and optionally CC to any third-party email address). + +![](https://c2.staticflickr.com/2/1644/24080560491_3aef056e8d_b.jpg) + +### Manage Multiple Portfolios ### + +JStock allows you to manage multiple portfolios. This feature is useful if you are using multiple stock brokers. You can create a separate portfolio for each broker and manage your buy/sell/dividend transactions on a per-broker basis. You can switch different portfolios by choosing a particular portfolio under "Portfolio" menu. The following screenshot shows a hypothetical portfolio. + +![](https://c2.staticflickr.com/2/1646/23536385433_df6c036c9a_c.jpg) + +Optionally you can enable broker fee option, so that you can enter any broker fees, stamp duty and clearing fees for each buy/sell transaction. If you are lazy, you can enable fee auto-calculation and enter fee schedules for each brokering firm from the option menu beforehand. Then JStock will automatically calculate and enter fees when you add transactions to your portfolio. + +![](https://c2.staticflickr.com/2/1653/24055085262_0e315c3691_b.jpg) + +### Screen Stocks with Built-in/Custom Indicators ### + +If you are doing any technical analysis on stocks, you may want to screen stocks based on various criteria (so-called "stock indicators"). For stock screening, JStock offers several [pre-built technical indicators][3] that capture upward/downward/reversal trends of individual stocks. The following is a list of available indicators. + +- Moving Average Convergence Divergence (MACD) +- Relative Strength Index (RSI) +- Money Flow Index (MFI) +- Commodity Channel Index (CCI) +- Doji +- Golden Cross, Death Cross +- Top Gainers/Losers + +To install any pre-built indicator, go to "Stock Indicator Editor" tab on JStock. Then click on "Install" button in the right-side panel. Choose "Install from JStock server" option, and then install any indicator(s) you want. + +![](https://c2.staticflickr.com/2/1476/23867534660_b6a9c95a06_c.jpg) + +Once one or more indicators are installed, you can scan stocks using them. Go to "Stock Indicator Scanner" tab, click on "Scan" button at the bottom, and choose any indicator. + +![](https://c2.staticflickr.com/2/1653/24137054996_e8fcd10393_c.jpg) + +Once you select the stocks to scan (e.g., NYSE, NASDAQ), JStock will perform scan, and show a list of stocks captured by the indicator. + +![](https://c2.staticflickr.com/2/1446/23795349889_0f1aeef608_c.jpg) + +Besides pre-built indicators, you can also define custom indicator(s) on your own with a GUI-based indicator editor. The following example screens for stocks whose current price is less than or equal to its 60-day average price. + +![](https://c2.staticflickr.com/2/1605/24080560431_3d26eac6b5_c.jpg) + +### Cloud Backup and Restore between Linux and Android JStock ### + +Another nice feature of JStock is cloud backup and restore. JStock allows you to save and restore your portfolios/watchlists via Google Drive, and this features works seamlessly across different platforms (e.g., Linux and Android). For example, if you saved your JStock portfolios to Google Drive on Android, you can restore them on Linux version of JStock. + +![](https://c2.staticflickr.com/2/1537/24163165565_bb47e04d6c_c.jpg) + +![](https://c2.staticflickr.com/2/1556/23536385333_9ed1a75d72_c.jpg) + +If you don't see your portfolios/watchlists after restoring from Google Drive, make sure that your country is correctly set under "Country" menu. + +JStock Android free version is available from [Google Play store][4]. You will need to upgrade to premium version for one-time payment if you want to use its full features (e.g., cloud backup, alerts, charts). I think the premium version is definitely worth it. + +![](https://c2.staticflickr.com/2/1687/23867534720_18b917028c_c.jpg) + +As a final note, I should mention that its creator, Yan Cheng Cheok, is pretty active in JStock development, and quite responsive in addressing any bugs.

For example, virt-manager is a popular GUI-based front-end for VM management. However, if you would like to use KVM on a headless server, GUI-based solutions will not be ideal. In fact, you can create and manage KVM VMs purely from the command line using kvm command-line wrapper script. Alternatively, you can use virsh which is an easier-to-use command-line user interface for managing guest VMs. Underneath virsh, it communicates wtih libvirtd service which can control several different hypervisors including KVM, Xen, QEMU, LXC and OpenVZ. + +A command-line management interface such as virsh is also useful when you would like to "automate" the provisioning and management of VMs. Also, the fact that virsh supports multiple hypervisors means you can manage different hypervisors via the same virsh interface. + +In this tutorial, I will demonstrate **how to run KVM from the command line by using virsh on Debian or Ubuntu**. + +### Step One: Verify Hardware Virtualization Support ### + +As a first step, verify that the host CPU is equipped with hardware virtualization extensions (e.g., Intel VT or AMD-V), which are required for KVM. The following command will do. + + $ egrep '(vmx|svm)' --color /proc/cpuinfo + +![](https://c2.staticflickr.com/2/1505/24050288606_758a44c4c6_c.jpg) + +If the output does not contain vmx or svm flag, it means the host CPU does not have hardware virtualization support. Thus you cannot use KVM on the host. After verifying that the host CPU comes with vmx or svm, proceed to install KVM next. + +For KVM, it is not required to run a 64-bit kernel on the KVM host, but generally it is recommended. + +### Step Two: Install KVM ### + +Using apt-get, install KVM and related user-space tools. + + $ sudo apt-get install qemu-kvm libvirt-bin + +During installation, libvirtd group (or libvirt-qemu on Debian) will be created, and your userID will be automatically added to the group. This will allows you to manage VMs as a non-root regular user. You can verify that by using id command, which will show your group IDs: + + $ id + +![](https://c2.staticflickr.com/6/5597/15432586092_64dfb867d3_c.jpg) + +If for some reason, libvirtd (or libvirt-qemu) is not found in your groupID list, you can manually add yourself to the group as follows. + +On Ubuntu: + + $ sudo adduser [youruserID] libvirtd + +On Debian: + + $ sudo adduser [youruserID] libvirt-qemu + +Reload updated group membership info as follows. Upon asked for a password, enter your login password. + + $ exec su -l $USER + +At this point, you should be able to run virsh as a regular user. As a test, try the command below, which will show a list of available VMs (currently none). If you do not encounter a permission error, it means everything is okay so far. + + $ virsh list + +---------- + + Id Name State + ---------------------------------------------------- + +### Step Three: Configure Bridged Networking ### + +One way to enable KVM VMs to access external networks is via a Linux bridge created on a KVM host. The bridge interconnects the virtual interfaces of VMs with the physical interface of the host, so that the VMs can send or receive traffic via the physical interface. This is called bridged networking. + +Here is how to create and configure a Linux bridge br0 for bridged networking with KVM. + +First, install a necessary package, and create a Linux bridge from the command line. + + $ sudo apt-get install bridge-utils + $ sudo brctl addbr br0 + +The next step is to configure Linux bridge in /etc/network/interfaces, so that the bridge is configured automatically upon boot. To use /etc/network/interfaces, you need to disable Network Manager on your system (if you are using it). Follow the [this instruction][1] to disable Network Manager. + +After disabling Network Manager, go ahead and configure Linux bridge br0 in /etc/network/interfaces as follows. + + #auto eth0 + #iface eth0 inet dhcp + + auto br0 + iface br0 inet dhcp + bridge_ports eth0 + bridge_stp off + bridge_fd 0 + bridge_maxwait 0 + +In the above I assume that eth0 is the primary network interface that is connected to external networks. Also, I assume that eth0 is getting its IP address via DHCP. Note that there is no configuration for eth0 in /etc/network/interface. The Linux bridge br0 takes up the configuration of eth0 as eth0 is enslaved to the bridge br0. + +Restart network service, and verify that Linux bridge is configured successfully. If successful, br0 should be assigned the eth0's DHCP IP address, and eth0 should not have any IP address assigned. + + $ sudo /etc/init.d/networking restart + $ ifconfig + +If for any reason eth0 still retains the IP address which is assigned to br0, you may have to explicitly remove the IP address from eth0. + +![](https://c2.staticflickr.com/2/1698/23780708850_66cd7ba6ea_c.jpg) + +### Step Four: Create a VM from the Command Line ### + +With KVM, the configuration of a VM is stored in a domain XML file. Thus, the first step to create a VM is to prepare its domain XML file. + +The following is a sample domain XML file of a VM. You can customize it as needed. + + + alice + f5b8c05b-9c7a-3211-49b9-2bd635f7e2aa + 1048576 + 1048576 + 1 + + hvm + + + + + + + destroy + restart + destroy + + /usr/bin/kvm + + + + +
+ + + + + + +
+ + + + + + +
+ + + + + + + + + +The above domain XML file defines the following VM. + +- 1GB memory, one vCPU and one hard drive. +- Disk image: /home/dev/images/alice.img. +- Boot from CD-ROM (/home/dev/iso/CentOS-6.5-x86_64-minimal.iso). +- Networking: one network interface bridged to br0 +- Remote access via VNC. + +The UUID string inside can be randomly generated. To get a random UUID, you can use uuid command-line tool. + + $ sudo apt-get install uuid + $ uuid + +Another way to create a domain XML file is to dump the domain information of an existing VM as follows. + + $ virsh dumpxml alice > bob.xml + +![](https://c2.staticflickr.com/6/5808/23968234602_25e8019ec8_c.jpg) + +### Step Five: Start VM from the Command Line ### + +Before starting a VM, you need to create its initial disk image. For that, you can use qemu-img command, which comes with qemu-kvm package you installed. The following command creates 10GB size empty disk image of qcow2 type: + + $ qemu-img create -f qcow2 /home/dev/images/alice.img 10G + +The advantage of using "qcow2" (as opposed to "raw") as a disk image format is that a "qcow2"-type disk image is not created as a full size (10GB) initially, but grows as the disk gets populated. So it is more space-efficient. + +Now you are ready to start a VM using the domain XML file you created earlier. The following command will create a VM, and automatically start it. + + $ virsh create alice.xml + +---------- + + Domain alice created from alice.xml + +**NOTE**: If you run the above command with an already created VM, it will wipe out the VM without warning. If you already created a VM, you can instead use the following command to just start the VM. + + $ virsh start alice.xml + +Verify that a new domain has been created and started successfully with: + + $ virsh list + +---------- + + Id Name State + ---------------------------------------------------- + 3 alice running + +Also, verify that the virtual interface for the VM (e.g., vnet0) is successfully added to the Linux bridge br0 that you created earlier. + + $ sudo brctl show + +![](https://c2.staticflickr.com/2/1546/23449585383_a371e9e579_c.jpg) + +### Step Six: Remote Access a VM ### + +To access the console of a running VM remotely, you can use any VNC client. + +First, find out the VNC port number for the VM as follows. + + $ sudo netstat -nap | egrep '(kvm|qemu)' + +![](https://c2.staticflickr.com/6/5633/23448144274_49045bc868_c.jpg) + +In this example, the VNC port number for alice VM is 5900. + +Then launch a VNC client, and connect to a VNC server running at :5900. In our example, the VM is supposed to boot into CentOS CD-ROM. + +![](https://c2.staticflickr.com/2/1533/24076369675_99408972a4_c.jpg) + +### Manage VMs with virsh ### + +The following lists common usages of virsh command. + +To create a new guest domain and start a VM: + + $ virsh create alice.xml + +To stop a VM and destroy a guest domain: + + $ virsh destroy alice + +To shutdown a VM (without destroying a domain): + + $ virsh shutdown alice + +To suspend a VM: + + $ virsh suspend alice + +To resume a suspended VM: + + $ virsh resume alice + +To access login console of a running VM: + + $ virsh console alice + +To autostart a VM upon host booting: + + $ virsh autostart alice + +To get domain information of a VM: + + $ virsh dominfo alice + +To edit domain XML of a VM: + + $ virsh edit alice + +The above will invoke the domain XML file of the VM with a default text editor. Any change in the XML will automatically be validated by libvirt for correctness. + +You can also manage VMs from within a virsh session. To create and enter a new virsh session, simply run: + + $ virsh + +At the virsh prompt, you can use any virsh commands. + +![](https://c2.staticflickr.com/6/5645/23708565129_b1ef968b30_c.jpg) + +### Troubleshooting ### + +1. I am getting the error while trying to create a VM: + + error: internal error: no supported architecture for os type 'hvm' + +You can get this error if your hardware does not have hardware virtualization support (e.g., Intel VT or AMD-V), which is required to run KVM. If you are getting this error even when your CPU comes with Intel VT or AMD-V, here are possible solutions: + +First, check if kvm kernel module is missing. + + $ lsmod | grep kvm + +If kvm kernel module is not loaded, you must load it as follows. + + $ sudo modprobe kvm_intel (for Intel processor) + $ sudo modprobe kvm_amd (for AMD processor) + +The second solution is adding "--connect qemu:///system" argument to virsh command as follows. This argument may be needed when you are using more than one hypervisor (e.g., VMware, VirtualBox) on the server hardware. + + $ virsh --connect qemu:///system create alice.xml + +2. I am getting the error while trying to access login console of my VM: + + $ virsh console alice + +---------- + + error: internal error: cannot find character device + +This error occurs because you did not define a console device in the VM's XML file.

With the help of the ssh-keygen tool, a user can create passphrase keys for both SSH protocol version 1 and version 2. ssh-keygen creates RSA keys for SSH protocol version 1 and RSA or DSA keys for use by SSH protocol version 2. - -### What is ssh-copy-id ### - -ssh-copy-id is a script that copies the local-host’s public key to the remote-host’s authorized_keys file. ssh-copy-id also append the indicated identity file to that machine’s ~/.ssh/authorized_keys file and assigns proper permission to the remote-host’s home. - -### SSH keys ### - -SSH keys provide better and secure way of logging into a linux server with SSH. After you run ssh-keygen, you will generate public key and private key. You can place the public key on any server, and then unlock it by connecting to it with a client that already has the private key. When the two match up, the system unlocks without the need for a password. - -### Setup SSH Login Without Password on CentOS and RHEL. ### - -This steps tested on CentOS 5/6/7, RHEL 5/6/7 and Oracle Linux 6/7. - -Node1 : 192.168.0.9 -Node2 : 192.168.l.10 - -#### Step One : #### - -Test the connection and access from node1 to node2 : - - [root@node1 ~]# ssh root@192.168.0.10 - The authenticity of host '192.168.0.10 (192.168.0.10)' can't be established. - RSA key fingerprint is 6d:8f:63:9b:3b:63:e1:72:b3:06:a4:e4:f4:37:21:42. - Are you sure you want to continue connecting (yes/no)? yes - Warning: Permanently added '192.168.0.10' (RSA) to the list of known hosts. - root@192.168.0.10's password: - Last login: Thu Dec 10 22:04:55 2015 from 192.168.0.1 - [root@node2 ~]# - -#### Step Two : #### - -Generate public and private keys using ssh-key-gen.

Even so, of the many millions of people using Linux-powered phones, few are able to run a mainline kernel on those phones, even if they have the technical skills to do the replacement. The sad fact is that no mainstream phone available runs mainline kernels. A session at the 2015 Kernel Summit, led by Rob Herring, explored this problem and what might be done to address it. - -When asked, most of the developers in the room indicated that they would prefer to be able to run mainline kernels on their phones — though a handful did say that they would rather not do so. Rob has been working on this problem for the last year and a half in support of Project Ara (mentioned in this article). But the news is not good. - -There is, he said, too much out-of-tree code running on a typical handset; mainline kernels simply lack the drivers needed to make that handset work. A typical phone is running 1-3 million lines of out-of-tree code. Almost all of those phones are stuck on the 3.10 kernel — or something even older. There are all kinds of reasons for this, but the simple fact is that things seem to move too quickly in the handset world for the kernel community to keep up. Is that, he asked, something that we care about? - -Tim Bird noted that the Nexus 1, one of the original Android phones, never ran a mainline kernel and never will. It broke the promise of open source, making it impossible for users to put a new kernel onto their devices. At this point, no phone supports that ability. Peter Zijlstra wondered about how much of that out-of-tree code was duplicated functionality from one handset to the next; Rob noted that he has run into three independently developed hotplug governors so far. - -Dirk Hohndel suggested that few people care. Of the billion phones out there, he said, approximately 27 of them have owners who care about running mainline kernels. The rest just want to get the phone to work. Perhaps developers who are concerned about running mainline kernels are trying to solve the wrong problem. - -Chris Mason said that handset vendors are currently facing the same sorts of problems that distributors dealt with many years ago. They are coping with a lot of inefficient, repeated, duplicated work. Once the distributors [Rob Herring] decided to put their work into the mainline instead of carrying it themselves, things got a lot better. The key is to help the phone manufacturers to realize that they can benefit in the same way; that, rather than pressure from users, is how the problem will be solved. - -Grant Likely raised concerns about security in a world where phones cannot be upgraded. What we need is a real distribution market for phones. But, as long as the vendors are in charge of the operating software, phones will not be upgradeable. We have a big security mess coming, he said. Peter added that, with Stagefright, that mess is already upon us. - -Ted Ts'o said that running mainline kernels is not his biggest concern. He would be happy if the phones on sale this holiday season would be running a 3.18 or 4.1 kernel, rather than being stuck on 3.10. That, he suggested, is a more solvable problem. Steve Rostedt said that would not solve the security problem, but Ted remarked that a newer kernel would at least make it easier to backport fixes. Grant replied that, one year from now, it would all just happen again; shipping newer kernels is just an incremental fix. Kees Cook added that there is not much to be gained from backporting fixes; the real problem is that there are no defenses from bugs (he would expand on this theme in a separate session later in the day). - -Rob said that any kind of solution would require getting the vendors on board. That, though, will likely run into trouble with the sort of lockdown that vendors like to apply to their devices. Paolo Bonzini asked whether it would be possible to sue vendors over unfixed security vulnerabilities, especially when the devices are still under warranty. Grant said that upgradeability had to become a market requirement or it simply wasn't going to happen. It might be a nasty security issue that causes this to happen, or carriers might start requiring it. Meanwhile, kernel developers need to keep pushing in that direction. Rob noted that, beyond the advantages noted thus far, the ability to run mainline kernels would help developers to test and validate new features on Android devices. - -Josh Triplett asked whether the community would be prepared to do what it would take if the industry were to come around to the idea of mainline kernel support. There would be lots of testing and validation of kernels on handsets required; Android Compatibility Test Suite failures would have to be treated as regressions. Rob suggested that this could be discussed next year, after the basic functionality is in place, but Josh insisted that, if the demand were to show up, we would have to be able to give a good answer. - -Tim said that there is currently a big disconnect with the vendor world; vendors are not reporting or contributing anything back to the community at all. They are completely disconnected, so there is no forward progress ever. Josh noted that when vendors do report bugs with the old kernels they are using, the reception tends to be less than friendly. Arnd Bergmann said that what was needed was to get one of the big silicon vendors to commit to the idea and get its hardware to a point where running mainline kernels was possible; that would put pressure on the others. But, he added, that would require the existence of one free GPU driver that got shipped with the hardware — something that does not exist currently. - -Rob put up a list of problem areas, but there was not much time for discussion of the particulars. WiFi drivers continue to be an issue, especially with the new features being added in the Android world. Johannes Berg agreed that the new features are an issue; the Android developers do not even talk about them until they ship with the hardware. Support for most of those features does eventually land in the mainline kernel, though. - -As things wound down, Ben Herrenschmidt reiterated that the key was to get vendors to realize that working with the mainline kernel is in their own best interest; it saves work in the long run. Mark Brown said that, in past years when the kernel version shipped with Android moved forward more reliably, the benefits of working upstream were more apparent to vendors. Now that things seem to be stuck on 3.10, that pressure is not there in the same way. The session ended with developers determined to improve the situation, but without any clear plan for getting there. - --------------------------------------------------------------------------------- - -via: https://lwn.net/Articles/662147/ - -作者：[Jonathan Corbet][a] -译者：[译者ID](https://github.com/译者ID) -校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 - -[a]:https://lwn.net/Articles/KernelSummit2015/ diff --git a/translated/tech/20151125 Running a mainline kernel on a cellphone.md b/translated/tech/20151125 Running a mainline kernel on a cellphone.md new file mode 100644 index 0000000000..e3a6c52e9f --- /dev/null +++ b/translated/tech/20151125 Running a mainline kernel on a cellphone.md @@ -0,0 +1,14 @@ +在手机上面运行主线内核 +对于自由软件来说，其最大的自由之一就是能够用一个更新或修改的版本来替换原始版本的程序。尽管如此，数千万使用linux内核作为支持的手机用户却很少能够在他们的手机上运行主线内核，即使他们拥有替换内核代码的专业技能。可悲的是，我们必须承认目前仍然无法使用到运行主线内核的主流手机。在由Rob Herring主持的2015届内核峰会上，与会人员共同探讨了这个问题，并进一步谈论了他们应该怎么做才能解决这个问题。 +当主持人提问的时候，在座的大多数开发人员都表示他们更喜欢在他们的手机上面运行主线内核，然而也有少数人持相反的看法。在Project Ara的支持下，Rob在这个问题上已经研究了近一年半的时间。但是最新的研究成果并不理想。 +Rob表示，有太多的树(out-of-tree)代码运行在手机上，主线内核只是缺少能使手机正常运行所必须的驱动。每台合格的手机都在运行着100万到300万的树(out-of-tree)代码。几乎所有的这些手机的内核版本都不超过3.1，有一些甚至更加古老。造成这种情况的原因有很多，但是有一点是很清楚的，在手机的世界里，一切都变化的太快以至于内核社区无法跟上它们的步伐。如果真是那样，他问到，我们还担心什么呢？ +Tim Bird指出，第一台Android手机Nexus1从来没有运行过任何一个主线内核，并且以后也不会。它打破了开源的承诺，也使得用户不可能做到将一个新的内核放到手机中。从这一点上来说，没有任何一款手机支持这种能力。Peter Zijlstra想知道从一台手机到另一台手机到底有多少正发挥作用的被复制的代码。Rob表示，迄今为止，他已经见到了三个独立开发的热插拔调速器。 +Dirk Hohndel提出了很少有人注意到的建议。他说，对于世界上的成千上亿万台手机，其中大约有百分之27的手机用户关心他们的手机是否运行着主线内核。剩下的用户仅仅只是想让他们的手机正常工作。或许那些关注手机是否在运行主线内核的开发者正在努力去解决这个令人不解的问题。 +Chris Mason说，那些手机卖家当前正面临着相同类型的问题，而这些问题也是那些linux发行版过去所面临过的问题。他们疲于应付大量的无效且重复和能被复制的工作。一旦这些发行版决定将他们的工作重心转入到主线内核而不是让它顺其自然的发展，那么问题将会变得好解决的多。解决问题的关键就是去帮助手机制造商们认识到他们可以通过同样的方式获利，形成这种认识的关键并不是通过来自用户的压力。这样一来，问题就可以解决了。 +Grant Likely提出了对于安全问题的担忧，这种担忧来自于那些不能升级他们的手机系统的android设备。他说，我们需要的是一个真正专为手机设立的发行市场。但是，只要手机卖家仍然掌控着手机中的应用软件，那么手机的同步更新将无法实现。我们接下来将面临一个很大的安全难题。Peter补充说，随着Stagefright漏洞的出现，难题已经出现在我们面前了。 +Ted Ts'o说，运行主线内核并不是他的主要关注点。他很乐于见到这个假期中所售卖的手机能够运行3.18或者4.1的内核，而不是继续停留在3.10。他认为这是一个更可能被解决的问题。Steve Rostedt认为，按照Ted Ts'o所说的那样去做并不能解决手机的安全问题，但是，Ted认为使用一个更新的内核至少可以让漏洞修复变得更加容易。Grant对此回应说，接下来的一年里，这一切都将再次发生。过渡到更新的内核也是一个渐进式的对系统的完善。Kees Cook补充说，我们无法从修复旧版本的内核漏洞的过程中得到太多的益处，真正的问题是我们没有对bug的应对措施。 +Rob说，任何一种解决方案都需要得到当前的手机供应商的支持。否则，由于厂商对应用到他们生产的手机上的操作系统的封锁，运行主线内核的策略将会陷入麻烦。Paolo Bonzini提问说是否可以因为那些没有修复的安全漏洞而控告手机厂商，尤其当手机仍然处于保修期内。Grant认为对于手机的可更新能力的保证必须来源于市场需求，否则是无法实现的。而促使它实现的原因可能会是一个严重的安全问题，然后用户开始对手机的可更新能力提出要求。同时，内核开发人员必须不断朝着这个方向努力。Rob表示，除了到目前为止指出的所有优点之外，运行主线内核也能帮助开发者对安卓设备上的新特性进行测试和验证。 +Josh Triplett提问说，如果手机产商提出对主线内核提供支持的想法，那么内核社区又将采取什么措施呢？那样将会针对手机各方面的特性要求对内核进行大量的测试和验证；Android的兼容性测试套件中出现的失败将不得不被再次回归。Rob提议这个问题将会在明年被讨论，即先将最基本的功能做好。但是，Josh强调说，如果这个需求出现了，我们就应该能够给出一个好的答案。 +Tim认为，当前，我们和厂商之间存在很大的脱节。厂商根本不会主动报告或者贡献任何反馈给社区。他们之间完全脱节了，这样的话永远不会有进步。Josh表示，当厂商们报告他们正在使用的旧内核的相关bug时，双方之间的接受度将变得更加友好。Arnd Bergmann认为，我们需要的是得到一个大芯片厂商对使用主线内核的认可，并且将该厂商的硬件提升到能够支持主线内核的运行的这样一个水平，而这样将会在其他方面增加负担。但是，他补充说，实现这个目标要求存在一个跟随硬件一起分发的自由GPU驱动程序——然而这种程序当前并不存在。 +Rob给存在问题的领域列了一个清单，但是现在已经没有太多的时间去讨论其中的细节了。WIFI驱动仍然是一个问题，尤其是当新特性被添加到Android设备上的时候。Johannes Berg对新特性仍然存在问题表示赞同；android的开发人员甚至在这些新特性被应用到Android设备上之前都不会去谈论它们是否存在问题。然而，对这些特性中的大多数的技术支持最终都会落实在主线内核中。 +随着会议逐渐接近尾声，Ben Herrenschmidt再次重申:实现在andoroid手机上运行主线内核的关键还是在于让厂商认识到使用主线内核是它们获得最大利润的最好选择。从长远看，使用主线内核能节省大量的工作。Mark Brown认为，以前，当搭载在Android设备上的内核版本以更稳定的方式向前推进的时候，上游工作的好处对运营商来说更加明显。以现在的情况来看，手机上的内核版本似乎停留在了3.10，那种压力是不一样的。这次会话以开发者决定进一步改善当前的状况而结束，但是却并没有对如何改善提出一个明确的计划。 From aca7feecd997150483b7ecfa2ab5ecf9bd981579 Mon Sep 17 00:00:00 2001 From: "Fuliang.Li" Date: Tue, 5 Jan 2016 09:49:48 +0800 Subject: [PATCH 17/41] =?UTF-8?q?[=E5=BC=80=E5=A7=8B=E7=BF=BB=E8=AF=91]=20?= =?UTF-8?q?20151208=206=20useful=20LibreOffice=20extensions?= MIME-Version: 1.0 Content-Type: text/plain;

In research, we occasionally open source software we write. We do this for two reasons. One, to promote the use of the tools we produce. And two, to learn more about the impact and issues other people face when using them. With this background of writing research software, I was tasked with redesigning the undergraduate software engineering course for second-year students at the University of Bradford. - -It was a challenge, as I was faced with 80 students coming for different degrees, including IT, business computing, and software engineering, all in the same course. The hardest part was working with students with a wide range of programming experience levels. Traditionally, the course had involved allowing students to choose their own teams, tasking them with building a garage database system and then submitting a report in the end as part of the assessment. - -I decided to redesign the course to give students insight into the process of working on real-world software teams. I divided the students into teams of five or six, based on their degrees and programming skills. The aim was to have an equal distribution of skills across the teams to prevent any unfair advantage of one team over another. - -### The core lessons ### - -The course format was updated to have both lectures and lab sessions. However, the lab session functioned as mentoring sessions, where instructors visited each team to ask for updates and see how the teams were progressing with the clients and the products. There were traditional lectures on project management, software testing, requirements engineering, and similar topics, supplemented by lab sessions and mentor meetings. These meetings allowed us to check up on students' progress and monitor whether they were following the software engineering methodologies taught in the lecture portion. Topics we taught this year included: - -- Requirements engineering -- How to interact with clients and other team members -- Software methodologies, such as agile and extreme programming approaches -- How to use different software engineering approaches and work through sprints -- Team meetings and documentations -- Project management and Gantt charts -- UML diagrams and system descriptions -- Code revisioning using Git -- Software testing and bug tracking -- Using open source libraries for their tools -- Open source licenses and which one to use -- Software delivery - -Along with these lectures, we had a few guest speakers from the corporate world talk about their practices in software product deliveries. We also managed to get the university’s intellectual property lawyer to come and talk about IP issues surrounding software in the UK, and how to handle any intellectual properties issues in software. - -### Collaboration tools ### - -To make all of the above possible, a number of tools were introduced. Students were trained on how to use them for their projects. These included: - -- Google Drive folders shared within the team and the tutor, to maintain documents and spreadsheets for project descriptions, requirements gathering, meeting minutes, and time tracking of the project. This was an extremely efficient way to monitor and also provide feedback straight into the folders for each team. -- [Basecamp][1] for document sharing as well, and later in the course we considered this as a possible replacement for Google Drive. -- Bug reporting tools such as [Mantis][2] again have a limited users for free reporting. Later Git itself was being used for bug reports n any tools by the testers in the teams -- Remote videoconferencing tools were used as a number of clients were off-campus, and sometimes not even in the same city. The students were regularly using Skype to communicate with them, documenting their meetings and sometimes even recording them for later use. -- A number of open source tool kits were also used for students' projects. The students were allowed to choose their own tool kits and languages based on the requirements of the projects. The only condition was that these have to be open source and could be installed in the university labs, which the technical staff was extremely supportive of. -- In the end all teams had to deliver their projects to the client, including complete working version of the software, documentation, and open source licenses of their own choosing. Most of the teams chose the GPL version 3 license. - -### Tips and lessons learned ### - -In the end, it was a fun year and nearly all students did very well. Here are some of the lessons I learned which may help improve the course next year: - -1. Give the students a wide variety of choice in projects that are interesting, such as game development or mobile application development, and projects with goals. Working with mundane database systems is not going to keep most students interested. Working with interesting projects, most students became self-learners, and were also helping others in their teams and outside to solve some common issues. The course also had a message list, where students were posting any issues they were encountering, in hopes of receiving advice from others. However, there was a drawback to this approach. The external examiners have advised us to go back to a style of one type of project, and one type of language to help narrow the assessment criteria for the students. -1. Give students regular feedback on their performance at every stage. This could be done during the mentoring meetings with the teams, or at other stages, to help them improve the work for next time. -1. Students are more than willing to work with clients from outside university! They look forward to working with external company representatives or people outside the university, just because of the new experience. They were all able to display professional behavior when interacting with their mentors, which put the instructors at ease. -1. A lot of teams left developing unit testing until the end of the project, which from an extreme programming methodology standpoint was a serious no-no. Maybe testing should be included at the assessments of the various stages to help remind students that they need to be developing unit tests in parallel with the software. -1. In the class of 80, there were only four girls, each working in different teams. I observed that boys were very ready to take on roles as team leads, assigning the most interesting code pieces to themselves and the girls were mostly following instructions or doing documentation. For some reason, the girls choose not to show authority or preferred not to code even when they were encouraged by a female instructor. This is still a major issue that needs to be addressed. -1. There are different styles of documentation such as using UML, state diagrams, and others. Allow students to learn them all and merge with other courses during the year to improve their learning experience. -1. Some students were very good developers, but some doing business computing had very little coding experience. The teams were encouraged to work together to prevent the idea that developer would get better marks than other team members if they were only doing meeting minutes or documentations. Roles were also encouraged to be rotated during mentoring sessions to see that everyone was getting a chance to learn how to program. -1. Allowing the team to meet with the mentor every week was helpful in monitoring team activities. It also showed who was doing the most work. Usually students who were not participating in their groups would not come to meetings, and could be identified by the work being presented by other members every week. -1. We encouraged students to attach licenses to their work and identify intellectual property issues when working with external libraries and clients. This allowed students to think out of the box and learn about real-world software delivery problems. -1. Give students room to choose their own technologies. -1. Having teaching assistants is key. Managing 80 students was very difficult, especially on the weeks when they were being assessed. Next year I would definitely have teaching assistants helping me with the teams. -1. A supportive tech support for the lab is very important. The university tech support was extremely supportive of the course. Next year, they are talking about having virtual machines assigned to teams, so the teams can install any software on their own virtual machine as needed. -1. Teamwork helps. Most teams exhibited a supportive nature to other team members, and mentoring also helped. -1. Additional support from other staff members is a plus. As a new academic, I needed to learn from experience and also seek advice at multiple points on how to handle certain students and teams if I was confused on how to engage them with the course. Support from senior staff members was very encouraging to me. - -In the end, it was a fun course—not only for the me as an instructor, but for the students as well. There were some issues with learning objectives and traditional grading schemes that still need to be ironed out to reduce the workload it produced on the instructors. For next year, I plan to keep this same format, but hope to come up with a better grading scheme and introduce more software tools that can help monitor project activities and code revisions. - --------------------------------------------------------------------------------- - -via: http://opensource.com/education/15/9/teaching-open-source-development-undergraduates - -作者：[Mariam Kiran][a] -译者：[译者ID](https://github.com/译者ID) -校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 - -[a]:http://opensource.com/users/mariamkiran -[1]:https://basecamp.com/ -[2]:https://www.mantisbt.org/ From 8e9f7304e048e221c0dd25f073717c7abc6bb696 Mon Sep 17 00:00:00 2001 From: Feng Wei Date: Wed, 6 Jan 2016 23:41:49 +0800 Subject: [PATCH 30/41] Update 20160104 What is good stock portfolio management software on Linux.md MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 申领任务 --- ...

For example, virt-manager is a popular GUI-based front-end for VM management. However, if you would like to use KVM on a headless server, GUI-based solutions will not be ideal. In fact, you can create and manage KVM VMs purely from the command line using kvm command-line wrapper script. Alternatively, you can use virsh which is an easier-to-use command-line user interface for managing guest VMs. Underneath virsh, it communicates wtih libvirtd service which can control several different hypervisors including KVM, Xen, QEMU, LXC and OpenVZ. - -A command-line management interface such as virsh is also useful when you would like to "automate" the provisioning and management of VMs. Also, the fact that virsh supports multiple hypervisors means you can manage different hypervisors via the same virsh interface. - -In this tutorial, I will demonstrate **how to run KVM from the command line by using virsh on Debian or Ubuntu**. - -### Step One: Verify Hardware Virtualization Support ### - -As a first step, verify that the host CPU is equipped with hardware virtualization extensions (e.g., Intel VT or AMD-V), which are required for KVM. The following command will do. - - $ egrep '(vmx|svm)' --color /proc/cpuinfo - -![](https://c2.staticflickr.com/2/1505/24050288606_758a44c4c6_c.jpg) - -If the output does not contain vmx or svm flag, it means the host CPU does not have hardware virtualization support. Thus you cannot use KVM on the host. After verifying that the host CPU comes with vmx or svm, proceed to install KVM next. - -For KVM, it is not required to run a 64-bit kernel on the KVM host, but generally it is recommended. - -### Step Two: Install KVM ### - -Using apt-get, install KVM and related user-space tools. - - $ sudo apt-get install qemu-kvm libvirt-bin - -During installation, libvirtd group (or libvirt-qemu on Debian) will be created, and your userID will be automatically added to the group. This will allows you to manage VMs as a non-root regular user. You can verify that by using id command, which will show your group IDs: - - $ id - -![](https://c2.staticflickr.com/6/5597/15432586092_64dfb867d3_c.jpg) - -If for some reason, libvirtd (or libvirt-qemu) is not found in your groupID list, you can manually add yourself to the group as follows. - -On Ubuntu: - - $ sudo adduser [youruserID] libvirtd - -On Debian: - - $ sudo adduser [youruserID] libvirt-qemu - -Reload updated group membership info as follows. Upon asked for a password, enter your login password. - - $ exec su -l $USER - -At this point, you should be able to run virsh as a regular user. As a test, try the command below, which will show a list of available VMs (currently none). If you do not encounter a permission error, it means everything is okay so far. - - $ virsh list - ----------- - - Id Name State - ---------------------------------------------------- - -### Step Three: Configure Bridged Networking ### - -One way to enable KVM VMs to access external networks is via a Linux bridge created on a KVM host. The bridge interconnects the virtual interfaces of VMs with the physical interface of the host, so that the VMs can send or receive traffic via the physical interface. This is called bridged networking. - -Here is how to create and configure a Linux bridge br0 for bridged networking with KVM. - -First, install a necessary package, and create a Linux bridge from the command line. - - $ sudo apt-get install bridge-utils - $ sudo brctl addbr br0 - -The next step is to configure Linux bridge in /etc/network/interfaces, so that the bridge is configured automatically upon boot. To use /etc/network/interfaces, you need to disable Network Manager on your system (if you are using it). Follow the [this instruction][1] to disable Network Manager. - -After disabling Network Manager, go ahead and configure Linux bridge br0 in /etc/network/interfaces as follows. - - #auto eth0 - #iface eth0 inet dhcp - - auto br0 - iface br0 inet dhcp - bridge_ports eth0 - bridge_stp off - bridge_fd 0 - bridge_maxwait 0 - -In the above I assume that eth0 is the primary network interface that is connected to external networks. Also, I assume that eth0 is getting its IP address via DHCP. Note that there is no configuration for eth0 in /etc/network/interface. The Linux bridge br0 takes up the configuration of eth0 as eth0 is enslaved to the bridge br0. - -Restart network service, and verify that Linux bridge is configured successfully. If successful, br0 should be assigned the eth0's DHCP IP address, and eth0 should not have any IP address assigned. - - $ sudo /etc/init.d/networking restart - $ ifconfig - -If for any reason eth0 still retains the IP address which is assigned to br0, you may have to explicitly remove the IP address from eth0. - -![](https://c2.staticflickr.com/2/1698/23780708850_66cd7ba6ea_c.jpg) - -### Step Four: Create a VM from the Command Line ### - -With KVM, the configuration of a VM is stored in a domain XML file. Thus, the first step to create a VM is to prepare its domain XML file. - -The following is a sample domain XML file of a VM. You can customize it as needed. - - - alice - f5b8c05b-9c7a-3211-49b9-2bd635f7e2aa - 1048576 - 1048576 - 1 - - hvm - - - - - - - destroy - restart - destroy - - /usr/bin/kvm - - - - -
- - - - - - -
- - - - - - -
- - - - - - - - - -The above domain XML file defines the following VM. - -- 1GB memory, one vCPU and one hard drive. -- Disk image: /home/dev/images/alice.img. -- Boot from CD-ROM (/home/dev/iso/CentOS-6.5-x86_64-minimal.iso). -- Networking: one network interface bridged to br0 -- Remote access via VNC. - -The UUID string inside can be randomly generated. To get a random UUID, you can use uuid command-line tool. - - $ sudo apt-get install uuid - $ uuid - -Another way to create a domain XML file is to dump the domain information of an existing VM as follows. - - $ virsh dumpxml alice > bob.xml - -![](https://c2.staticflickr.com/6/5808/23968234602_25e8019ec8_c.jpg) - -### Step Five: Start VM from the Command Line ### - -Before starting a VM, you need to create its initial disk image. For that, you can use qemu-img command, which comes with qemu-kvm package you installed. The following command creates 10GB size empty disk image of qcow2 type: - - $ qemu-img create -f qcow2 /home/dev/images/alice.img 10G - -The advantage of using "qcow2" (as opposed to "raw") as a disk image format is that a "qcow2"-type disk image is not created as a full size (10GB) initially, but grows as the disk gets populated. So it is more space-efficient. - -Now you are ready to start a VM using the domain XML file you created earlier. The following command will create a VM, and automatically start it. - - $ virsh create alice.xml - ----------- - - Domain alice created from alice.xml - -**NOTE**: If you run the above command with an already created VM, it will wipe out the VM without warning. If you already created a VM, you can instead use the following command to just start the VM. - - $ virsh start alice.xml - -Verify that a new domain has been created and started successfully with: - - $ virsh list - ----------- - - Id Name State - ---------------------------------------------------- - 3 alice running - -Also, verify that the virtual interface for the VM (e.g., vnet0) is successfully added to the Linux bridge br0 that you created earlier. - - $ sudo brctl show - -![](https://c2.staticflickr.com/2/1546/23449585383_a371e9e579_c.jpg) - -### Step Six: Remote Access a VM ### - -To access the console of a running VM remotely, you can use any VNC client. - -First, find out the VNC port number for the VM as follows. - - $ sudo netstat -nap | egrep '(kvm|qemu)' - -![](https://c2.staticflickr.com/6/5633/23448144274_49045bc868_c.jpg) - -In this example, the VNC port number for alice VM is 5900. - -Then launch a VNC client, and connect to a VNC server running at :5900. In our example, the VM is supposed to boot into CentOS CD-ROM. - -![](https://c2.staticflickr.com/2/1533/24076369675_99408972a4_c.jpg) - -### Manage VMs with virsh ### - -The following lists common usages of virsh command. - -To create a new guest domain and start a VM: - - $ virsh create alice.xml - -To stop a VM and destroy a guest domain: - - $ virsh destroy alice - -To shutdown a VM (without destroying a domain): - - $ virsh shutdown alice - -To suspend a VM: - - $ virsh suspend alice - -To resume a suspended VM: - - $ virsh resume alice - -To access login console of a running VM: - - $ virsh console alice - -To autostart a VM upon host booting: - - $ virsh autostart alice - -To get domain information of a VM: - - $ virsh dominfo alice - -To edit domain XML of a VM: - - $ virsh edit alice - -The above will invoke the domain XML file of the VM with a default text editor. Any change in the XML will automatically be validated by libvirt for correctness. - -You can also manage VMs from within a virsh session. To create and enter a new virsh session, simply run: - - $ virsh - -At the virsh prompt, you can use any virsh commands. - -![](https://c2.staticflickr.com/6/5645/23708565129_b1ef968b30_c.jpg) - -### Troubleshooting ### - -1. I am getting the error while trying to create a VM: - - error: internal error: no supported architecture for os type 'hvm' - -You can get this error if your hardware does not have hardware virtualization support (e.g., Intel VT or AMD-V), which is required to run KVM. If you are getting this error even when your CPU comes with Intel VT or AMD-V, here are possible solutions: - -First, check if kvm kernel module is missing. - - $ lsmod | grep kvm - -If kvm kernel module is not loaded, you must load it as follows. - - $ sudo modprobe kvm_intel (for Intel processor) - $ sudo modprobe kvm_amd (for AMD processor) - -The second solution is adding "--connect qemu:///system" argument to virsh command as follows. This argument may be needed when you are using more than one hypervisor (e.g., VMware, VirtualBox) on the server hardware. - - $ virsh --connect qemu:///system create alice.xml - -2. I am getting the error while trying to access login console of my VM: - - $ virsh console alice - ----------- - - error: internal error: cannot find character device - -This error occurs because you did not define a console device in the VM's XML file. Add the following inside the "device" section of the XML file. - - - - - --------------------------------------------------------------------------------- - -via: http://xmodulo.com/use-kvm-command-line-debian-ubuntu.html - -作者：[Dan Nanni][a] -译者：[译者ID](https://github.com/译者ID) -校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 - -[a]:http://xmodulo.com/author/nanni -[1]:http://xmodulo.com/disable-network-manager-linux.html diff --git a/translated/tech/20160104 How to use KVM from the command line on Debian or Ubuntu.md b/translated/tech/20160104 How to use KVM from the command line on Debian or Ubuntu.md new file mode 100644 index 0000000000..6f9f3690cb --- /dev/null +++ b/translated/tech/20160104 How to use KVM from the command line on Debian or Ubuntu.md @@ -0,0 +1,297 @@ + +怎样在ubuntu和debian中用命令行使用KVM +================================================================================ +有很多不同的方式去管理运行在KVM管理程序上的虚拟机。例如，virt-manager就是一个流行的基于图形用户界面的前端虚拟机管理工具。然而，如果你想要在没有图形窗口的服务器环境下使用KVM，那么基于图形用户界面的解决方案显然是行不通的。事实上，你可以纯粹的使用包装了kvm命令行脚本的命令行来管理KVM虚拟机。作为替代方案，你可以使用virsh这个容易使用的命令行用户接口来管理客户虚拟机。在virsh中，它通过和libvirtd服务通信来达到控制虚拟机的目的，而libvirtd可以控制几个不同的虚拟机管理器，包括KVM，Xen，QEMU，LXC和OpenVZ。 + 当你想要对虚拟机的前期准备和后期管理实现自动化操作时，像virsh这样的命令行管理工具是非常有用的。同样，virsh支持多个管理器的事实也意味着你可以通过相同的virsh接口去管理不同的虚拟机管理器。 + 在这篇文章中，我会示范**怎样在ubuntu和debian上通过使用virsh命令行去运行KVM**。 + +### 第一步：确认你的硬件平台支持虚拟化 ### + +作为第一步，首先要确认你的主机CPU配备了硬件虚拟化拓展（e.g.，Intel VT或者AMD-V)，这是KVM对硬件的要求。下面的命令可以检查硬件是否支持虚拟化。 + + $ egrep '(vmx|svm)' --color /proc/cpuinfo + +![](https://c2.staticflickr.com/2/1505/24050288606_758a44c4c6_c.jpg) + + 如果在输出中不包含vmx或者svm标识，那么就意味着你的主机cpu不支持硬件虚拟化。因此你不能在你的机器上使用KVM。确认了主机cpu存在vmx或者svm之后，接下来开始安装KVM。 +对于KVM来说，它不要求运行在拥有64位内核系统的主机上，但是通常我们会推荐在64位系统的主机上面运行KVM。 + +### 第二步：安装KVM ### + +使用apt-get安装KVM和相关的用户空间工具。 + + $ sudo apt-get install qemu-kvm libvirt-bin + +安装期间，libvirtd组（在debian上是libvirtd-qemu组）将会被创建，并且你的用户id将会被自动添加到该组中。这样做的目的是让你可以以一个普通用户而不是root用户的身份去管理虚拟机。你可以使用id命令来确认这一点，下面将会告诉你怎么去显示你的组id： + + $ id + +![](https://c2.staticflickr.com/6/5597/15432586092_64dfb867d3_c.jpg) + +如果因为某些原因，libvirt（在debian中是libvirt-qemu）没有在你的组id中被找到，你也可以手动将你自己添加到对应的组中，如下所示： +在ubuntu上： + + $ sudo adduser [youruserID] libvirtd + +在debian上： + + $ sudo adduser [youruserID] libvirt-qemu + +按照如下形式重修载入更新后的组成员关系。如果要求输入密码，那么输入你的登陆密码即可。 + + $ exec su -l $USER + +这时，你应该可以以普通用户的身份去执行virsh了。做一个如下所示的测试，这个命令将会以列表的形式列出可用的虚拟机（当前的列表是空的）。如果你没有遇到权限问题，那意味着迄今为止一切都是正常的。 + + $ virsh list + +---------- + + Id Name State + ---------------------------------------------------- + +### 第三步：配置桥接网络 ### + +为了使KVM虚拟机能够访问外部网络，一种方法是通过在KVM宿主机上创建Linux桥来实现。创建之后的桥能够将虚拟机的虚拟网卡和宿主机的物理网卡连接起来，因此，虚拟机能够发送和接受由物理网卡发送过来的流量数据包。这种方式叫做网桥连接。 +下面将告诉你如何创建并且配置网桥，我们称它为br0. +首先，安装一个必需的包，然后用命令行创建一个网桥。 + + $ sudo apt-get install bridge-utils + $ sudo brctl addbr br0 + +下一步就是配置已经创建好的网桥，即修改位于/etc/network/interfaces的配置文件。我们需要将该桥接网卡设置成开机启动。为了修改该配置文件，你需要关闭你的操作系统上的网络管理器（如果你在使用它的话）。跟随[操作指南][1]的说明去关闭网络管理器。 + 关闭网络管理器之后，接下来就是通过修改配置文件来配置网桥了。 + + #auto eth0 + #iface eth0 inet dhcp + + auto br0 + iface br0 inet dhcp + bridge_ports eth0 + bridge_stp off + bridge_fd 0 + bridge_maxwait 0 + + +在上面的配置中，我假设eth0是主要网卡，它也是连接到外网的网卡，同样，我假设eth0将会通过DHCP得到它的ip地址。注意，之前在/etc/network/interfaces中还没有对eth0进行任何配置。桥接网卡br0引用了eth0的配置，而eth0也会受到br0的制约。 +重启网络服务，并确认网桥已经被成功的配置好。如果成功的话，br0的ip地址将会是eth0的被自动分配的ip地址，而且eth0不会被分配任何ip地址。 + + $ sudo /etc/init.d/networking restart + $ ifconfig + +如果因为某些原因，eth0仍然保留了之前分配给了br0的ip地址，那么你可能必须明确的删除eth0的ip地址。 + +![](https://c2.staticflickr.com/2/1698/23780708850_66cd7ba6ea_c.jpg) + +###第四步：用命令行创建一个虚拟机 ### + +对于虚拟机来说，它的配置信息被存储在它对应的xml文件中。因此，创建一个虚拟机的第一步就是准备一个与主机名对应的xml文件。 +下面是一个示例xml文件，你可以根据需要手动修改它。 + + + alice + f5b8c05b-9c7a-3211-49b9-2bd635f7e2aa + 1048576 + 1048576 + 1 + + hvm + + + + + + + destroy + restart + destroy + + /usr/bin/kvm + + + + +
