I don't believe it can be the qemu-kvm package, since upstream qemu git
HEAD didn't fix it, while it wasn't broken on centos.
Can you show 'dpkg -l | grep ipxe' on the system from comment #19?
If the new ipxe didn't solve it, then my next guess would be seabios...

Thanks! So it sounds like the problem is actually in ipxe.
Saucy has a new ipxe (from 9 days ago). However simply installing it
alongside precise's qemu-kvm probably won't work.

I tried upstream qemu. But the issue not solved yet.
On Centos it work fine. qemu in Centos use gPXE instead iPXE. Please see
