The main thing is that I used raring, not quantal. This could be
somethign which was fixed in either qemu or the kernel.

No, i did so from a single host. I used two laptops connected over an
ethernet cable (with the one beign pxe+dhcp server for the other, my
regular install setup).

No switch involved. I'll try using just quantal first on the VM host, but
wouldn't that be interesting if adding a switch caused this!

Thanks for the .xml. Nothing stands out there...
