Overview
Create a Snapshot Image
If the virtual machine has more than one storage device attached, they all must be snapshot at the same time to produce a consistent snapshot that can be reverted to.
Procedure
Shutdown the Target Guest
virsh shutdown <vm-name>
Identify all Storage Devices
virsh dumpxml <vm-name>
Look for <disk> definitions. The disk definition specifies the source and the format of the virtual storage device. Example:
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source file='/main-storage-pool/appproxy.qcow2'/>
...
</disk>
