kvm-81 and Windows XP with HugePages

kvm-81 and Windows XP with HugePages

[Bernhard Held]

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.

Host:  2.6.27.10 x86_64 Xenon Quad
Guests:
- Windows XP Prof. 32 bit, 2 vcpus
- 2.6.27.10 x86_64, 4 vcpus
- 2.6.27.10 x86, 4 vcpus

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,
