I am using QEMU 1.1.0, the latest libvirt (from the git repo, but I've also tried release 0.10.0). Host os is Ubuntu 10.04 and the VM os is also 10.04.

I am getting the qemu version from qemu-system-x86_64 --version so I know its the one that is recognized from path.

As far as I know, no other versions have been installed on the host machine.

A couple of questions:
        - What libvirt version?
        - What OS/version?
        - What qemu-kvm version?

Can you reproduce the same issue with latest libvirt and qemu-kvm ? (that's what I have on
my F18 machine -- libvirt-0.10.2-3.fc18.x86_64, qemu-kvm-1.2.0-11.fc18.x86_64) ?

That's the machine type I have.

# grep machine /etc/libvirt/qemu/f17jeos-3.xml
    <type arch='x86_64' machine='pc-1.2'>hvm</type>

your distro calls the binary as?)
