hi guys,
according to an commit in Oct. 2013 there was a patch added to the SDK
which allows to attach an existing snapshot to a virtual machine:

sdk: regenerate against the latest api
[..]
- added ability to attach a disk snapshot to the virtual machine
[..]
I think this may be related to the new backup API:
http://www.ovirt.org/Features/Backup-Restore_API_Integration
can anyone give me an pointer on how to this through the python-sdk? Or
is there an example for this anywhere to be found? Thanks!
It should be something like this:
#!/usr/bin/python
import ovirtsdk.api
import ovirtsdk.xml
api = ovirtsdk.api.API(
url="https://fedora.example.com/ovirt-engine/api";,
username="admin@internal",
password="****",
insecure=True,
debug=False
)
# Find the snapshot that contains the disk that we want to backup:
vm = api.vms.get("myvm")
snaps = vm.snapshots.list()
snap = None
for current in snaps:
if current.get_description() == "mysnap":
snap = current
# Find the disk that we want to backup:
disks = snap.disks.list()
disk = None
for current in disks:
if current.get_name() == "mydisk":
disk = current
# Find the backup appliance VM:
appliance = api.vms.get("backupvm")
# Attach the disk to the backup appliance:
appliance.disks.add(disk)
# Tell the backup appliance to perform the backup, connecting
# with SSH, or with any other way that the backup appliance
# supports.
# Bye:
api.disconnect()
With a similar script you can also disconnect the disk from the backup
appliance.
