Question

我在Ubuntu 10.10上运行VMWare Workstation。我有一系列虚拟机，我每周都会克隆一次。

我编写了一个bash脚本，循环遍历每个虚拟机，轻轻地挂起它，克隆它，然后尝试恢复它。

问题是，VM没有恢复，所以我必须手动恢复它们。我试图找出如何修改我编写的脚本以确保VM恢复。我已经包含了脚本和生成的日志文件的示例，显示了错误消息。

#!/bin/bash

##Author:   William Cooper
##Date: 2/15/2011
## Purpose:     Perform full backups of Virtual Machines
##      Running under VMWare Workstation

## Script won't run if the /nas directory doesn't exist
## The /nas directory is a mounted Buffalo Terastation
## Check /etc/fstab if this mountpoint is broken
   BACKUPDEST="/nas"

## No need to modify
   HOST=`hostname`
   DATEFILE=`/bin/date +%G%m%d`

## Run Command to find list of VM names:
## this will only be the name of the vm, no path and no .vmx
   VMLIST=`vmrun list | grep '/' | cut -d'/' -f3 | cut -d'.' -f1`

## Initialize Counter variable used to cycle through VMs in VMARRAY variable
   COUNTER=1

## Run Command to find list of VM Names and then store them in an Array:
## This will include full pathnames
   VMARRAY=( `vmrun list | grep '/'` )

错误：无法启动UI，因为当前环境中没有显示服务器

Answer 1

您可以将nogui参数用于start命令，例如：

vmrun start yourmachine.vmx nogui

请参阅：http://www.vmware.com/pdf/vix180_vmrun_command.pdf

Answer 2

由于没有找到可靠的答案，我只是接受在这些特定情况下无法解决的问题。

Ubuntu 10.10 x64
VMware Workstation 7

解决方案：关闭VMware Workstation并选择虚拟机“在后台运行” 在那之后完美无瑕地工作。

Answer 3

尝试在运行vmware工作站的终端TTY上执行echo $ DISPLAY。 echo $ DISPLAY将返回如下：1000.0 你需要设置在脚本中导出DISPLAY =“：1000.0”。然后脚本将恢复VM的.. 当我使用槟榔备份来恢复使用在槟榔中运行的postscript恢复我的VM时，我发现这是有效的。

Answer 4

如果问题是因为您从ssh会话运行vmrun，则另一个解决方案可能是在服务器上运行屏幕会话。

机器上的

正在运行：

screen -S vmware

在客户端计算机上，

ssh vmware-machine
screen -x vmware
vmrun start /path/to/vm.vmx

VMware虚拟机无法从命令行恢复
