In case the create operation  (VDSM -> LIBVIRT) does not return (as in the above described scenario). 
It should have beed solved by the API timeout mechanism in libvirt, but this mechanism does not support such scenarios.

In order to solve this we need to build an internal timeout mechanism in VDSM->Libvirt communiction, it looks like impossible to do so since libvirt does not support cancel (and clean up) of creation command.

I only just noticed the needinfo set for me on this BZ, sorry for the delay.  This situation should be solved by the work we're doing for BZ 692663.
