如何在 XenServer 7 GUI 虚拟机（VM）上提高屏幕分辨率
|
||
============
|
||
|
||
### 介绍
|
||
|
||
**目的**
|
||
|
||
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。
|
||
|
||
|
||
|
||
本篇的目标是提高 XenServer 7 GUI 虚拟机（VM）的屏幕分辨率
|
||
|
||
**要求**
|
||
|
||
访问 XenServer 7 系统的权限
|
||
|
||
**难易性**
|
||
|
||
简单
|
||
|
||
**惯例**
|
||
|
||
* `#` - 给定命令需要作为 root 用户权限运行或者使用 `sudo` 命令
|
||
* `$` - 给定命令作为常规权限用户运行
|
||
|
||
### 指导
|
||
|
||
**获得 VM UUID**
|
||
|
||
首先，我们需要获得想要提升分辨率的虚拟机的 UUID。
|
||
|
||
```
|
||
# xe vm-list
|
||
uuid ( RO) : 09a3d0d3-f16c-b215-9460-50dde9123891
|
||
name-label ( RW): CentOS 7
|
||
power-state ( RO): running
|
||
```
|
||
|
||
提示：如果你将此 UUID 保存为 shell 变量会节省一些时间：
|
||
|
||
```
|
||
# UUID=09a3d0d3-f16c-b215-9460-50dde9123891
|
||
```
|
||
|
||
**关闭 VM**
|
||
|
||
优雅地关闭 VM 或使用 `xe vm-vm-shutdown` 命令：
|
||
|
||
```
|
||
# xe vm-shutdown uuid=$UUID
|
||
```
|
||
|
||
**更新 VGA 的 VIDEORAM 设置**
|
||
|
||
检查你目前的 VGA 的 VIDEORAM 参数设置：
|
||
|
||
```
|
||
# xe vm-param-get uuid=$UUID param-name="platform" param-key=vga
|
||
std
|
||
# xe vm-param-get uuid=$UUID param-name="platform" param-key=videoram
|
||
8
|
||
```
|
||
|
||
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:videoram=16
|
||
```
|
||
|
||
**启动 VM**
|
||
|
||
```
|
||
# xe vm-start uuid=$UUID
|
||
```
|
||
|
||
