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:

commit 72e67dd5406f3c193234697ce88d92dbe64759d7 Author: Michael pasternak <mpastern@redhat.com> Date: Wed Oct 30 11:24:19 2013 +0200 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. -- Dirección Comercial: C/Jose Bardasano Baos, 9, Edif.
