virsh destroy 和 virsh undefine 有什么区别

我是服务器和虚拟机的新手，想知道两者之间的区别

virsh destroy

和

virsh undefine

答案1

让我们来看看man virsh：

destroy domain
  Immediately terminate the domain domain.  This doesn't give the domain
  OS any chance to react, and it's the equivalent of ripping the power cord
  out on a physical machine. In most cases you will want to use
  the shutdown command instead.  However, this does not delete any
  storage volumes used by the guest, and if the domain is persistent, it
  can be restarted later.


undefine domain
  Undefine a domain. If the domain is running,
  this converts it to a transient domain, without stopping it. 
  If the domain is inactive, the domain configuration is removed.

这表明这destroy是一种非常不礼貌地关闭域的方法，而undefine只是将其转换为临时域或删除其配置。
