### Objective 如果你想要将 XenServer 虚拟机作为远程桌面，默认的分辨率可能不能满足你的要求。
If your intention is to use XenServer's virtual machine as a remote desktop, the default screen resolution may not be satisfactory for your purposes. 
![Default xenserver screen VM resolution](https://linuxconfig.org/images/xenserver-7-default-screen-resolution.png) ![Default xenserver screen VM resolution](https://linuxconfig.org/images/xenserver-7-default-screen-resolution.png)
The objective is to increase screen resolution on XenServer 7 GUI Virtual Machine. 本篇的目标是提高 XenServer 7 GUI 虚拟机（VM）的屏幕分辨率
### Requirements ### 要求
Privileged access to XenServer 7 system. 访问 XenServer 7 系统的特权
### Difficulty ### 难易性
EASY 简单
### Conventions ### 惯例
* **#** - requires given command to be executed with root privileges either directly as a root user or by use of `sudo` command * **#** - 给定命令需要作为 root 用户权限运行或者使用 `sudo` 命令
* **$** - given command to be executed as a regular non-privileged user * **$**- 给定命令作为常规权限用户运行
### Instructions ### 指导
### Obtain VM UUID ### 获得 VM UUID
首先，我们需要获得想要提升分辨率的虚拟机的 UUID。
First, we need to obtain a relevant UUID of the Virtual Machine on which we wish to increase a screen resolution:
``` ```
# xe vm-list # xe vm-list
uuid ( RO) : 09a3d0d3-f16c-b215-9460-50dde9123891 uuid ( RO) : 09a3d0d3-f16c-b215-9460-50dde9123891
name-label ( RW): CentOS 7 name-label ( RW): CentOS 7
power-state ( RO): running power-state ( RO): running
``` ```
Tip: It saves some time if you save this UUID as a shell variable:
提示：如果你将此 UUID 保存为 shell 变量会节省一些时间：
``` ```
# UUID=09a3d0d3-f16c-b215-9460-50dde9123891 # UUID=09a3d0d3-f16c-b215-9460-50dde9123891
``` ```
### Shutdown VM ### 关闭 VM
优雅地关闭 VM 或使用 `xe vm-vm-shutdown` 命令：
Gracefully shutdown your VM or shutdown using `xe vm-vm-shutdown` command:
``` ```
# xe vm-shutdown uuid=$UUID # xe vm-shutdown uuid=$UUID
``` ```
### Update VGA a VIDEORAM settings ### 更新 VGA 的 VIDEORAM 设置
检查你目前的 VGA 的 VIDEORAM 参数设置：
Check your current VGA a VIDEORAM parameter settings:
``` ```
# xe vm-param-get uuid=$UUID param-name="platform" param-key=vga # xe vm-param-get uuid=$UUID param-name="platform" param-key=vga
std std
# xe vm-param-get uuid=$UUID param-name="platform" param-key=videoram # xe vm-param-get uuid=$UUID param-name="platform" param-key=videoram
8 8
``` ```
To increase a screen resolution, update your VGA to `std` ( if its already set, nothing needs to be done ) and `videoram` to some greater number in megabytes. Eg. 16:
要提升屏幕的分辨率，将 VGA 更新到 `std` （如果已经设置过，就不需要做什么），并将 `videoram` 调大几兆，如设置成 16：
``` ```
# xe vm-param-set uuid=$UUID platform:vga=std # xe vm-param-set uuid=$UUID platform:vga=std
# xe vm-param-set uuid=$UUID platform:videoram=16 # xe vm-param-set uuid=$UUID platform:videoram=16
``` ```
### Start VM ### 启动 VM
``` ```
# xe vm-start uuid=$UUID # xe vm-start uuid=$UUID
