14.3. Creating virtual machine snapshots by using the web console

To save the state of a virtual machine (VM) in a snapshot, you can use the RHEL web console.

Prerequisites

You have installed the RHEL 10 web console.
For instructions, see Installing and enabling the web console.
The web console VM plugin is installed on your system.
The VM uses file-based storage. To ensure that this is the case, perform the following steps:
1. In the Virtual machines interface of the web console, click the VM of which you want to create a snapshot.
2. In the Disks pane of the management overview, check the Source column of the listed devices. In all devices that list a source, this source must be File.

Procedure

Log in to the RHEL 10 web console.
In the Virtual machines interface of the web console, click the VM of which you want to create a snapshot.
A management overview of the VM opens.
In the Snapshots pane of the management overview, click the Create snapshot button.
Enter a name for the snapshot, and optionally a description.
Click Create.

Verification

To ensure that creating the snapshot has succeeded, check that the snapshot is now listed in the Snapshots pane of the VM.
Verify that the snapshot has been created as external. To do so, use the following command on the command line of the host:
```
# virsh snapshot-dumpxml <Testguest1> <Snapshot1> | grep external

  <disk name='vda' snapshot='external' type='file'>
```
If the output of this command includes snapshot='external', the snapshot is external and therefore supported by Red Hat.
