Inspecting snapshots

In this short recipe, we are going to see examples on how to obtain more information on existing virtual machine snapshots.

Getting ready

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

How to do it...

To inspect a snapshot, run the following commands:

1. 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:~#

2. Get information about the running snapshot:

root@kvm:~# virsh snapshot-info kvm1 --snapshotname 1492797458
Name: 1492797458
Domain: kvm1
Current: no
State: running
Location: internal
Parent: -
Children: 1
Descendants: 1
Metadata: yes

root@kvm:~#

3. Get information about the disk snapshot:
