[ovirt-users] Python-SDK4: Knowing snapshot status?

[nicolas at devels.es]

Hi,

I'm running ovirt-engine-sdk-python 4.2.4 and I'm performing some 
snapshot-related tasks. I'd like to somehow control the status of the 
snapshot in order to know when I'll be able to run the next 
snapshot-related operation.

For example, I'd like to create a new snapshot and then delete X oldest 
snapshots. After creating the snapshot I have to make sure the snapshot 
operation has concluded to run the deletion.

However, I'm unable to find a native way to get the status of a 
snapshot.

     In [1]: snap = conn.follow_link(vm.snapshots)[3]   # This returns 
one snapshot

     In [2]: snap.status

     In [3]: snap.status_detail

So both status-related properties return None. I've managed to find a 
"poorman's" way by doing this:

     while True:
         try:
             snaps_service.service(snap.id).remove()
         except Error, e:
             if e.code == 409:
                 sleep(30)
                 continue
             else:
                 break

Which works but is quite "tricky".

Is there a better way to do this?

Thanks.
