I suggest replacing "OVMF" with "ArmVirtQemu" in comments and strings as
well.

I'd also suggest renaming the method test_ovmf_virt() to
test_armvirtqemu_virt().

If that seems baroque, then I suggest "test_uefi_<machtype>" in both
patches #2 and #3.

(Sorry about my obsession with these names; just trying to capture the
existing "vernacular".)
