[libvirt-users] libvirt-python Create External Snapshot

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
