Ah interesting. So this machine only has the qemu-kvm binary installed,
none of the other non-KVM binaries.

What is the version of libvirt that you have ? Until fairly recently
libvirt would not detect the fact that /usr/bin/qemu-kvm was able to
support non-KVM modes, which could be causing some of the pain here.
