在windows 8.1中启动从其他地方拷贝过来的虚拟机（暂停状态的），提示如下信息：

Not enough physical memory is available to power on this virtual machine with its configured settings.
To fix this problem, adjust the additional memory settings to allow more virtual machine memory to be swapped.
If you were able to power on this virtual machine on this host computer in the past, try rebooting the host computer. Rebooting may allow you to use slightly more host memory to run virtual machines.

其实并不是内存不够的原因，而是需要的权限不对，这个时候，可以找到vmware.exe右键，以管理员的身份运行即可。
