From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How likely is this to work? KVM/VFIO Single GPU Passthrough (www.youtube.com)

I've been wanting to make a proper switch over to Linux for a while now. I've currently have a dual-boot setup but still mostly use Windows. The majority of my games should work without fuss, but I'd like to have a simple solution for running the handful of things that don't work in Linux, such as my WMR VR headset and a handful of Steam games.

Linked is a video on Single GPU passthrough with KVM/VFIO, which I'd like to try.

Before I try this, I'd like a sense of how likely it is to work, and I'm wondering if there might be a better solution I don't know of. I'm also open to any tips you might have about speeding up the transition between Host/Guest OS.

Here are the specs of my machine:

Motherboard: MSI B550 A-Pro

CPU: AMD Ryzen 7 3700X (no integrated graphics)

GPU: Nvidia GeForce RTX 3070

RAM: 32GB DDR4 3200MHz

Host OS: Manjaro

Guest OS: Windows 10 Pro

I don't know if you can do it in software with passthrough, as the guest controls the hardware and would need to coordinate things.

Using a KVM would be a hardware solution that would permit for one monitor, though.

I considered a KVM or something similar, but I still need access to the host machine in parallel (ideally side-by-side so I can step through the code running in the guest from a debugger in my dev environment on the host). I've already got a multi-monitor setup, so dedicating one of them to a VM while testing stuff isn't too much of a big deal - I just have to keep track of whether or not my hands are on separate keyboard+mouse for the guest :)

Ah, I gotcha. One keyboard/mouse, VM guest output in a window on the host would be ideal.

Run a VNC or RDP server on the guest VM, connect with a client on the host? That won't have quite the performance -- if you're debugging a 3d game and playing it as part of it, you'll get latency, so that won't be a good solution for OP -- but that may not matter for your use case.
