Yeah there have been applied multiple fixes in that regard already.

https://github.com/oVirt/vdsm/commit/5b5c58580e20ffaf3ceff7193f4c28cbadd8c42f
and 
https://github.com/oVirt/vdsm/commit/26bfc74765aed35af6d17cfad1ed8115eef650f1

So it looks like that both of you are using oVirt 3.1, which contains 
neither of those two fixes. AFAIK only the first one is in oVirt 3.2 and 
the second one is in oVirt 3.3

Unfortunately not much I can recommend besides to upgrade at some point. :-(
