Notes

mdeslaur

needs qemu-kvm patch (included in 1.0) http://git.kernel.org/?p=virt/kvm/qemu-kvm.git;a=commit;h=5ff4e36c oneiric and precise don't have spice enabled in the qemu-kvm build. This probably only has an impact in environments where a precise guest is running on a host with spice enabled, and recent enough to supports async io. Downgrading priority to low.
