emulation failed (pagetable) rip

[Bachman Kharazmi]

Hi
I'm running a kvm-84 host with 2.6.28.7. Guests are two lenny and one
Centos52 running a oracle db for test purpose.
The host is a  C2D E8400  @ 3.00GHz, 4G. HostOS debian lenny x86_64.
I've lenny guests on on other hosts where I do not get this errors. I
assume it is the centos guest which cause the output like this:

Can you test with just one guest to make sure?

It looks like the guest started at 2137.06 is at fault.

[Parag Warudkar]

On today's git, while installing Ubuntu Jaunty I am getting a load of -

[ 1962.876257] __ratelimit: 1457842 callbacks suppressed

It happens right after Partition formatting sequence in Jaunty install.
The installation fails with unable to mount partition vda.

QEMU PC emulator version 0.9.1 (kvm-84)

kvm -drive file=ubuntu-jaunty.img,if=virtio,boot=on -net nic,model=virtio 
-net user -m 1024M -cdrom /media/New\ Volume/Downloads/ubuntu-9.04-desktop-amd64.iso 

If I remove the file=...,if=virtio and instead use plain old hda=... the 
install succeeds - probably safe to say virtio is at fault?

Haven't recently tested KVM so can't say when this started.

Any ideas?
