mmm, not sure it's working, because we need to use running "machine version", not qemu version

I'll think about this tomorrow.

Maybe could we already increment qemu release version (2.4.0.2) with a temp patch 

Then when we live migrate, if source qemu < 2.4.0.2 , then we pass old pxe-rom to target vm 

(upload qemu-server and pve-qemu-kvm packages at the time)

bad, but we really need to update those old ROMs (user already reported bugs). 
Any better idea?
