Hi Lionel,

i wrote this function for deleting all the VM snapshots and waiting
the deletion:


def clean_snap_ovirt(vm_data):
    vm, connection = vm_data
    vms_service = connection.system_service().vms_service()
    vm_service = vms_service.vm_service(vm.id)
    snapshots_service = vm_service.snapshots_service()
    snapshots = snapshots_service.list()
    for snapshot in snapshots:
        if snapshot.snapshot_type != types.SnapshotType.REGULAR:
            continue
        snapshot_service = snapshots_service.snapshot_service(snapshot.id)
        snapshot_service.remove()
        snapshot = snapshot_service.get()
        while snapshot.snapshot_status == types.SnapshotStatus.LOCKED:
            try:
                snapshot = snapshot_service.get()
            except:
                break
            print("Still removing snapshot of  {0} ....".format(vm.name))
            time.sleep(10)


vm_data is a tuple containing the connection to ovirt and the output
of a vm lookup by name

If you want to delete only specific snapshot, you have to filter out
by description, or id or something else.
