Windows下VirtualBox的默认安装路径是
C:\Program files\Oracle\VirtualBox
假设虚拟机的名称是 MyHost，那么：
C:\Program files\Oracle\VirtualBox\VBoxManage.exe startvm MyHost --type headless % 开机，且无界面
C:\Program files\Oracle\VirtualBox\VBoxManage.exe startvm MyHost --type gui % 开机，带界面
C:\Program files\Oracle\VirtualBox\VBoxManage.exe controlvm MyHost pause % 暂停
C:\Program files\Oracle\VirtualBox\VBoxManage.exe controlvm MyHost savestate % 休眠
C:\Program files\Oracle\VirtualBox\VBoxManage.exe controlvm MyHost poweroff % 强制关机
C:\Program files\Oracle\VirtualBox\VBoxManage.exe controlvm MyHost resume % 从暂停状态恢复
