I'm curious about this idea but feeling a bit stuck with the configuration. Could anyone share their experience? Which operating system are you using and which documentation did you refer to for installation? How have you handled setting up VFIO in practice?

I have a setup running now. Fedora 28 with AMD FX 8350 and a Gigabyte 990FX card. Just turn off the driver for the GPU you want to test, enable IOMMU in GRUB, then start the VM. It’s not complicated and there are no major problems.

It's understandable to feel frustrated with a non-standard installation process. I'm here to help you understand how it compares to a typical Windows setup and see if the effort is worthwhile. Let's break it down.

It operates smoothly with no significant problems. It's mainly used for entertainment purposes, alongside other Windows and gaming setups. What concerns you?

I'm using Manjaro with iommu installed, and I turned off the drivers so the GPU isn't showing up on my monitor—which is fine. The main problem is I can't switch the VM to UEFI mode; probably because of that, my GPU is only partially recognized.

thanks to @Electronics Wizardy i do have it working. i have 2 Xeon X5650's - 12 core's (6 core's for the VM). 24GB of ram (12GB for the VM). R9 290X for the VM. i only play Overwatch on that VM and my fps only drops into the 50's and 40's if there's a lot on screen... whenever there are a lot of characters on screen i get those fps drops, but that could be because of a load of different things. i've been tweaking this setup for a few weeks and i got it to run a lot better. when i first set it up Overwatch was practically unplayable. it would lag with a lot less stuff on screen. @Electronics Wizardy recommended that i pinned my cpu core's and i haven't figured out how to do that yet so it might be because i need to do that still...

You're asking about the VM's UEFI settings and whether it's compatible with the board's IOMMU features. It seems you want to confirm if the system supports this mode and if the IOMMU is functioning properly.

I just moved to Fedora to check performance improvements. Regarding UEFI mode, I've seen online that newer GPUs require it. Could I have misunderstood? The groups worked well, and I managed to isolate my GPU into the VM. However, it appeared the VM was using a default renderer instead of my actual card, even though Windows recognized the real hardware.

You're using Virt-Manager in Fedora for virtual machines. Your VM configuration is set up with the tools and settings you installed, but I can't view or provide screenshots directly. Let me know if you need help with anything else!

I'm currently reinstalling Fedora due to an issue that caused it to crash during startup.
