In this recipe, we are going to edit the XML definition of an existing snapshot and examine the changes.
For this recipe, we are going to need the following:
- A libvirt host with the QEMU toolset
- The snapshots we created in the Creating snapshots recipe
To edit a snapshot, run the following:
- List all available snapshots for the specified KVM instance:
root@kvm:~# virsh snapshot-list kvm1 Name Creation Time State ------------------------------------------------------------ 1492797458 2017-04-21 17:57:38 +0000 running kvm1_ext_snapshot 2017-04-21 18:08:49 +0000 disk-snapshot root@kvm:~#
- Edit the disk snapshot and change its name and description:
root@kvm:~# virsh snapshot-edit kvm1 --snapshotname kvm1_ext_snapshot --rename <domainsnapshot> <name>kvm1_ext_snapshot_renamed</name> <description>Disk only external snapshot for kvm1</description> ... root@kvm:~#
- List the snapshots...
