I'm experiencing very similar thing. I'm not sure if it's the same, but in my case without kvm supported hardware, booting freezes on 'GRUB Loading'. I've done some debugging and if I run command provided by libvirt (minus -S), I get the same behaviour. But, if I replace boot=on with boot=off in -drive, it boots and works as expected.
I'm experiencing this on Ubuntu 10.04 (libvirt 0.7.5).
