Listing snapshots

In the previous recipe, we create two snapshots of the same KVM instance: one internal and one disk-only, external snapshot. In this recipe, we are going to learn how to list existing snapshots.

Getting ready

For this recipe, we are going to need:

• A libvirt host with the QEMU toolset
• A running KVM instance
• The snapshots we created in the Creating snapshots recipe

How to do it...

To list all existing snapshots, follow the next steps:

1. List all 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:~#

2. List only the disk-based snapshots:

root@kvm:~# virsh snapshot-list --disk-only kvm1
 Name                Creation Time              State
------------------------------------------------------------
 kvm1_ext_snapshot...
