#创建虚拟机,不建议使用virsh create,停机后,virsh list --all查看不到虚拟机信息,推荐使用virsh define+virsh start命令
[root@VM_166_143 data]# virsh create test.xml 或者 [root@VM_166_143 data]# virsh define test.xml [root@VM_166_143 data]# virsh start test.xml
#常用命令
#关闭虚拟机 virsh shutdown demo #取消定义虚拟机 virsh undefine demo #重启虚拟机 virsh reboot demo #强制关闭虚拟机 virsh destroy demo #列出所有虚拟机 virsh list --all
