[libvirt-users] libvirt-python Create External Snapshot

[Roger Jin]

Hi Libvirt,
Does libvirt-python currently support the creation of external snapshots?
I ran

domain.snapshotCreateXML(xml)

where xml is

<domainsnapshot>
  <name>snap1</name>
  <description>Snapshot of OS install and updates</description>
  <disks>
    <disk name='vda'>
            <source file='/home/potato/libvirt/backups/test-snap1.qcow2'/>
    </disk>
  </disks>
</domainsnapshot>

And got the following error:
    if ret is None:raise libvirtError('virDomainSnapshotCreateXML()
failed', dom=self)
libvirt.libvirtError: unsupported configuration: disk 'vda' must use
snapshot mode 'internal'

Is this expected?  Thanks!

Sincerely,
Roger Jin
