Subject: Re: [edk2] KVM: MTRR: fix memory type handling if MTRR is completely disabled
Date: Thu, 1 Oct 2015 16:12:01 +0200 [thread overview]

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?
