** Description changed: - Bug 1291321 shows that qemu VMs cannot be migrated from a host running - 12.04 to a host running 14.04. + ===================================== + Impact: qemu VMs cannot be migrated from 12.04->14.04 hosts + Test Case: migrate a vm from p->t host, using disk on a NFS share.

A part of this solution requires pxe roms built from the precise ipxe sources. Such a package is built for T and U in ppa:serge-hallyn/qemu- migration2. It builds fine and only installs 5 new romfile under /usr/share/qemu. (The source package is called ipxe-precise, the binary package kvm-ipxe- precise.)
