--- Comment #63 from Maxim Levitsky (maximlevitsky@xxxxxxxxx) ---
I tried the patch from comment 55 and it works for me (3970X).

Maybe you have something disabled in the config? You need synic,'vapic' hyper-v
enlightenments disabled, and on top of that you need x2apic and svm (nested
virtualization) to be disabled in the guest cpu config. 

And you need to have PIC reinject policy to be set to 'discard'.
