Hi,

I had the same experience with the latest beta version, 
ovirt-engine-3.3.0-1.el6.noarch

After create VM from template was initiated, two rows where inserted in 
the table "async_tasks" .
After the creation finished successfully (and the VM could be used), one 
row was deleted from the table
but one was left there.

If you restart ovirt-engine then the VMs (created from template) where 
deleted. Their disks were not deleted.
The left over row was also deleted.

If you manually delete the left-over row from the table before you 
restart ovirt-engine, then
the VM is not deleted.

Is there a BZ for this to monitor it's fix progress?

regards,

Giannis
