Passthrough Contention Problems with Console and Linux VM
-
Has anyone had success in making PCI passthrough work to a Linux Desktop VM (in particular Hyprland)?
I am getting very mixed results but generally a lot of issues where there seams to be Seat contention for my USB devices (keyboard/mouse) and my GPU vs the Console (Cirrus VGA Driver/Virtual Input Devices).
I've been working through a series of blacklist and priority settings (mostly ChatGPT generated sadly) but was wondering if there is a more standard approach to this that someone knows/has figured out.
I can't imagine it's as hard as I'm making it so hoping one of your experts can help me here as I'm brand new to XCPNG!
Thank you!

Hi,
The virtual console is slow because of the Cirrus VGA driver. We have some changes in the pipes that might improve it. I'm adding @TeddyAstie in the convo so he could give you some test packages to see if it's better

@olivierlambert great thank you. I think there is a Git issue also I found today 744. Not directly related but also driver related where the VGA disable function doesn’t work.
I think if in whatever future driver implementation there can be some more control of how it binds it would be really helpful for these use cases.
Thank you!

We'll release at some point an update where you could switch to a new VGA type (virtio-vga) which is a LOT faster and allow better resolutions for the VM console. We have test packages in the next days if you want to provide some feedback,

@olivierlambert yes please

@TeddyAstie will post them when he fixed some basic bugs
