Second option, here is what I am getting after appending the options
that you mentioned to my invocation of qemu:
qemu-system-i386: -device virtio-blk-device,drive=drive0: No
'virtio-bus' bus found for device 'virtio-blk-device'
Actually, this is the command line that I am using:
qemu-system-i386 -pflash ./bios.bin -drive
file=fat:./hda-contents,id=drive0,if=none,format=raw -device
virtio-blk-device,drive=drive0
Removing all the options after hda-contents my OVMF starts correctly,
and I can get to the UEFI shell without issues.
I have not been able to try the first option yet, for I don't have the
guestfish utility. I'll try and get it.
