@Laszlo: When thinking about it, even though it is a very stupid

technically there isn't really a difference between
'extended-tseg-mbytes=0' and
'extended-tseg-mbytes=8'
that's correct
(of course the second option will still provide a
fw_cfg info about the size etc., but the guest will behave the same
way), right?
- it's not fw_cfg but a made-up register in PCI config space
- the guest won't behave *exactly* the same way, technically speaking,
but the end result will be 8MB in both cases, yes.
That brings me to another question (maybe even more stupid), what
size
does OVMF choose if I specify 'extended-tseg-mbytes=6'?
6MB.
Thanks,
