<disks>
<disk name='/home/qcow2/disk.0'>
<driver type='qcow2'/>
<source file='/home/qcow2/disk.3'/>

</disks>
</domainsnapshot>
2. when i execute the command , a mistake occurred:
# virsh snapshot-create qcow2 deployment.1
error:
argument unsupported: unable to handle disk requests in snapshot
3. i add the parameter '--disk-only', another mistake occurred:
# virsh snapshot-create qcow2 deployment.1 --disk-only
