Sometimes, the cloning function of the kvm/vmware virtual machine is used to quickly replicate the installed system. But after cloning, will find no eth0 network card. Workaround: 1.

Today's XenServer also has a snapshot technology, if you are doing some dangerous operations, you can take a snapshot, so that even if there is a problem, you can quickly recover. Snapshots can save the state of a virtual machine at a point in time, and can be recovered whenever an error occurs. But if you forget to take snapshots, or if you have trouble making snapshots every time, or if some
