VMware virtual machines wont resume from the command line
提问by Lucretius
I'm running VMWare Workstation on Ubuntu 10.10. I have a series of virtual machines that I clone every week.
我在 Ubuntu 10.10 上运行 VMWare Workstation。我每周都会克隆一系列虚拟机。
I've written a bash script that cycles through each of the virtual machines, softly suspends it, clones it, and then attempts to resume it.
我编写了一个 bash 脚本，它在每个虚拟机之间循环，轻轻地挂起它，克隆它，然后尝试恢复它。
The problem is, the VM's do not resume, so I have to manually resume them. I'm trying to figure out how I can modify the script I've written to ensure the VMs resume. I've included the script and a sample of the generated logfile showing the error message.
问题是，VM 无法恢复，所以我必须手动恢复它们。我想弄清楚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显示错误消息的生成日志文件的示例。

##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 '/'` )

Since no solid answer has been found I'm just going to accept that under these specific circumstances there is no fix.
由于没有找到可靠的答案，我只能接受在这些特定情况下没有解决办法。
- Ubuntu 10.10 x64
- VMware Workstation 7
- Ubuntu 10.10 x64
- VMware 工作站 7
Solution: Close down VMware Workstation and choose for the VMs to "Run in the Background" Works flawlessly after that.
解决方案：关闭 VMware Workstation 并选择让虚拟机“在后台运行”之后即可正常工作。

You could use the nogui paramater to the start command, e.g:
您可以使用 nogui 参数来启动命令，例如：
vmrun start yourmachine.vmx nogui

try doing echo $DISPLAY on your terminal TTY where vmware workstation runs. The echo $DISPLAY will return like :1000.0 you need to set export DISPLAY=":1000.0" in your script. then the script will resume the VM's.. i found this works when i use areca backup to resume my VM using postscript run in areca.
尝试在运行 vmware 工作站的终端 TTY 上执行 echo $DISPLAY。echo $DISPLAY 将返回 :1000.0 您需要在脚本中设置 export DISPLAY=":1000.0" 。然后脚本将恢复 VM 的 .. 我发现这在我使用 areca 备份使用在 areca 中运行的 postscript 恢复我的 VM 时有效。

if the problem is because you are running vmrun from a ssh session, then another solution might be run a screen session on the server.
如果问题是因为您从 ssh 会话运行 vmrun，那么另一种解决方案可能是在服务器上运行屏幕会话。
on the machine Workstation is running:
在工作站运行的机器上：
screen -S vmware
on the client machine,
在客户端机器上，
ssh vmware-machine
screen -x vmware
vmrun start /path/to/vm.vmx
