Example Analysis of Snapshot Management for backup and restore of KVM Virtual Machine

Editor to share with you the KVM virtual machine backup and restore snapshot management example analysis, I hope you will learn something after reading this article, let's discuss it together!

Assume that the vm1 virtual machine is installed and running

Create a xml file, vm1_snapshot.xml, with the following contents:

Vm1_snapshot

Ubuntu 12.10 AMD64 server

Now run the following command to create the snapshot for vm1:

Virsh snapshot-create vm1. / vm1_snapshot.xml

Domain snapshot vm1_snapshot created from'. / vm1_snapshot.xml'

Now check vm1's snapshot.

Virsh snapshot-list vm1

Name Creation Time State

Vm1_snapshot 2012-11-14 14:46:44 + 0800 running

Now log in to the running vm1 and add a file under / root/

Touch xy

OK, replace the current vm1 with vm1_snapshot (or restore vm1 to the state saved by vm1_snapshot)

Virsh snapshot-revert vm1 vm1_snapshot

Log in to vm1 again and there is no xy file under / root. The restore was successful.

If you do not need this vm1_snapshot, you can delete it with the following command:

Virsh snapshot-delete vm1 vm1_snapshot

Domain snapshot vm1_snapshot deleted

Root@host2:~/kvm# virsh snapshot-list vm1

Name Creation Time State
