Engine and VDSM Logs

Template import task fails.

To reproduce, import a (big) sparse file using GlusterFS.
Since GlusterFS doesn't support sparse files efficiently [1], the import task will take days and be cleared by Engine.

== Unvalidated hint ==

I'm not sure, but it seems the qemu-img process continued running during a previous test (I missed to check this time).
