One thing that isn't clear from the website is that it requires two GPUs, one for the host and one for the VM.

Does an iGPU fill the same criteria?

Yes it does. Intel usually is the host adapter.

The problem is that you have to have a monitor plugged in the windows card otherwise it goes all wonky. At that point you could just use a KVM....

The blurb at the top says "allows the use of a KVM [...] without an attached physical monitor, keyboard or mouse." Is that not correct?

I mean it behaves like a software KVM, at which point you can use a hardware KVM without the added latency penalty due to memory copy....

I used it for a bit a while back and would only use it again if I absolutely had to. Cases like that are very limited though, using an external GPU enclosure without a monitor attached to it is one. Being dumb enough to try to use a gimped mining GPU that doesn't have any video outputs is another.

If anyone is interested, the main developer, who goes by 'gnif' spends a decent amount of time on the dedicated Looking Glass sub-forum on the Level1Techs forum, here:

https://forum.level1techs.com/c/software/lookingglass/142

Level1Techs also has a ton of information and help both on the forum, and their YouTube channel, about setting up Looking Glass and VFIO. The main host of the YouTube channel, Wendell, has forgotten more about nitty-gritty system administration than I will likely ever know in my lifetime. He also just seems like a genuinely good human being.

I think you forgot to mention why you didn't like it.

Just want to say that gnif is amazing. He is always happy to help out people on the looking glass support discord. Plus he's absolutely dedicated to continuing to improve the software he writes and the ecosystem around it. Top notch guy.
