Windows XP Prof. freezes few seconds after booting on kvm-81 with hugepages. The cpu load stays at 200% (on 2 cores), the screen is black.
The process can't be killed, a reboot is required.

The same guest runs fine
- without hugepages or
- with kvm-79 with hugepages.
Never tried with kvm-80.

Can you check kvm-80? This will help pinpointing the evil commit.

WXP works with kvm-80 and hugepages. There are no problems with kvm-80 and all three guests.

kvm-80 isn't that bad ;-)

Works here. Since there's an mmu fix queued, please try kvm-82 when it's released.

Of course I will try kvm-82 and report the result.

Thanks for reviewing,
