Dietmar has made change on qemu 2.4, but after release of proxmox 4.0.

so we have qemu 2.4 with pxe and qemu 2.4 with efi.

Ah thanks - why do we need so complex code? Couldn't we simply use the 
machine type we already force on migration and pass? If somebody is 
using machine type 2.2 or 2.3 he can't have efi. An we already query the 
machine code through qmp on each migration.
