[vfio-users] Code 43 when using Quadro K420 on another system.

[Eddie Yen]

Hi Pim,

This is what I goning to write and solved vesafb issue on this working.

Not only set video=vesafb:off, but also need to set following settings in
GRUB.

GRUB_TERMINAL=console
GRUB_GFXPAYLOAD_LINUX=text

Even that, The monitor still shows on K420 and I still got Code 43 in the
VM.
At least it solved BAR 3 issue.

I never tried GRUB_GFXMODE yet, I'll give it a shot.

Thanks,
