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.
