Now, I can also add, that the problem is only when I allow VM to use
more than one core, so with option  for example:
-smp 8,cores=4,threads=2,sockets=1 and other combinations like -smp
4,threads=1 its not working, and without it I am always running VM
without problems

Any ideas what can it be? or any idea what would help to find out what
is causing this?
