Oh, interesting. This seems to be what I am experiencing now (see my
answer to Laszlo). When I am now using additional emulated graphics,
I can see the boot output (on the emulated display) until it stops
at a certain point .<br>

I guess your card is from a different manufacturer then
and thus has a different ROM? Because if I try to use the
standard ROM of my card (as in not explicitly passing any
rom file to the VM at all), I don't get any output on the
monitor connected to the card at all.<br>
What exactly do you mean with "AMD cards also have the
option of running as secondary graphics devices in many
cases"?</blockquote>

<div>You have two options when you assign a GPU to a VM, you
can do it in addition to the emulated graphics
(cirrus/VGA/QXL) or instead of the emulated graphics. You
indicated following my blog, so I assume you removed the
emulated graphics when you added the assigned GPU. This
is necessary for NVIDIA GeForce, but many users have found
that AMD cards also work when added to the VM
configuration with the emulated graphics. No ROM is
necessary on the assigned GPU in this case. The emulated
graphics will show the BIOS and early boot output, then
the assigned graphics can be enabled. This mode doesn't
actually require OVMF, it works with SeaBIOS too.</div>

<div>Anyway, I'm curious to the answers to Laszlo's
questions. I've also seen hangs at the TianoCore splash
with certain USB host controllers assigned. Thanks,</div>
