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?
