Dave, could you try with tip/master, Ingo pushed out all the fixes

Lacking that, could you perhaps provide the .config you use for your
guest and a kvm invocation?

I used a defconfig with KVM_GUEST=y, which was enough to enable kvmclock
support and then started with:

kvm -kernel defconfig-build/arch/x86/boot/bzImage -nographic -append "console=ttyS0" -smp 2
