Hi,

 

There is a way to cancel a running task  -  look here http://lists.ovirt.org/pipermail/users/2014-November/028946.html

I was able to stop snapshot deletion this way.

 

Best, Mikhail.

Any suggestions ?

THe task has been hung for 5 days now, I can't start the machine or destroy it.

I'm seeing these errors in the logs which look related to the problem:
