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'
You must use the libvirt.VIR_DOMAIN_SNAPSHOT_CREATE_DISK_ONLY flag if you don't want to include the memory state of the VM or include the <memory> element in the above XML.
