Comment 13 for bug 1074207

Thanks Marc. This works well here. When using UEFI it adds the <loader>OVMF.fd</loader> line to the xml and it doesn't when using the default. Booting with UEFI I see the OVMF.fd firmware screen and without UEFI I do not. Also, the way Marc implemented this, no changes are needed to libvirt.

Small nit: I've only ever seen the OVMF file referred to as "OVMF.Fd" as opposed to "OVMF.fd". This will likely need to change if we end up shipping this file anyway....
