[ovirt-users] Snapshot Locked for an extended period of time

[Simon Hallam]

Hi All,

I’ve recently written a script which:
   1. Takes a snapshot with memory.
   2. Creates a VM from that snapshot.
   3. Exports the snapshot to the export domain.
   4. Deletes the snapshot.
   5. Deletes the cloned VM.

Whilst running the script for the first time last night, the script
timed out whilst deleting the snapshot on the VM at step 4.

Now the logs are filled with:

I have attached the log of when the snapshot started deleting (2016-02-
24 23:51:17,094). 

Any idea what's gone wrong? What are my next steps to clear this?

Cheers,

Simon
