linux下vmware挂起虚拟机后再恢复有时候会出现如下错误：

Unable to change virtual machine power state: Internal error.

一开始以为是vmware的设置有问题，后来在网上终于找到答案：

Ran into this while running Vmware Workstation under Ubuntu Jaunty. I got an error while shutting down the machine through an NX session.

This is a result of a zombie ‘vmware-vmx’ process running. All you need to do is kill the process. This command sends ’signal 9′ to the process. When sent to a program, SIGKILL causes it to terminate immediately. In contrast to SIGTERM and SIGINT, this signal cannot be caught or ignored. For more information: more sigkill info.

killall -s9 vmware-vmxAfter that, I was able to start up the virtual machine without issue.

即找到vmware-vmx进程（对应于该虚拟机的，每个虚拟机都有一个这样的进程，用Ps aux | grep vmware-vmx命令可看到具体进程情况，找到对应于该虚拟机的）杀死就行
