Indeed.

This is Ubuntu 12.04 to Ubuntu 14.04. I think the 14.04 one is correct, and don't want to run with a non-standard qemu there. Can I use a different ROM (e.g. the old one) with a command line option just for the migrated machines? Obviously when they reboot, they'l get a hardware change (which is fine). Obviously the iPXE ROM makes no difference when the machine is running, it's purely the size which is causing an issue. -- Alex Bligh
