He's also should be able to attach just the .efi file or install graphics drivers via qxl.

* Yes, capturing the OVMF debug log should be the first step when
reporting apparent OVMF issues.
You can get that log without resorting to the raw QEMU command line.
Modify your domain XML like this:
- add the following attribute to the root element of the domain XML:
xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0' <-- this one
- add the following XML fragment near the end of the domain XML, as a
direct child of the <domain> element:
This will send the OVMF log to "/tmp/guest_name.log".
* Regarding the specific case: a UEFI oprom for a GPU may easily be
buggy even if it matches the card. If you are experimenting with
"similar" drivers, all bets are off. Please buy a decent card (Alex has
recommended the GTX750 several times; I myself bought one on his
recommendation, and have had zero problems with it). Or else, at least
get an officially supported driver binary from the manufacturer, please.
