dumpxml of the rawhide guest from virsh

Opening as a rawhide kernel bug, but it could also be a problem with the host kernel or qemu instance.

I have a rawhide kvm guest running on a Fedora 10 host. The guest's ring buffer is continually being spammed several times per second with this message:

end_request: I/O error, dev vda, sector 0

...everything seems to be working OK otherwise.

The guest is currently running:

2.6.31-0.94.rc4.fc12.x86_64

...but the problem has existed for quite some time with earlier kernels too. The host is running:

2.6.27.25-170.2.72.fc10.x86_64

...and has:

qemu-0.9.1-12.fc10.x86_64
kvm-74-10.fc10.x86_64

The guest is using the virtio block driver for the disk. Let me know if any other info would be useful.
