Is there a way to use Looking Glass https://looking-glass.hostfission.com in UnRaid instead of passing through the entire graphics card to one VM or does the concept of Looking Glass not really work with the mainly headless idea of UnRaid, it would be good to run multiple VM's with full GPU usage from one card.

I could be wrong, but since unraid doesn't have a full desktop with accelerated GPU support, I don't think it's going to work.

Also, with looking glass, you'd still need to pass through an entire gpu to a VM (for example windows), what you'd then could do (not with unRAID as jonathanm correctly pointed out) with a linux host is have the framebuffer of the windows gpu copied to the frame buffer of your linux host so you get a kind of picture-in-picture, and you only need 1 cable.

The only advantage I can see with that, is you'd only need 1 cable, disadvantage is you'd need a proper Linux desktop built into Unraid to use it.  I looked at it before and struggled to see the use case tbh.

I'm bumping this since this is the only thread on this topic I found searching.

 

gnif had a prototype working that did guest to guest copy, although I think it had some issues he hadn't work through. So in theory you could have a linux VM with a graphics card that can view another windows VM with a graphics cards output. But I don't think its there yet.

 

I wouldn't definitely like to see this working in unraid some day.

Those willing to run the unstable master version and are using AMD hardware on the client may get a substantial performance improvement as I just added GL_AMD_pinned_memory support. On my test system I am seeing a substantial improvement in frame rate.

Edit: A kernel module has also been added to allow VM->VM communication.

The software is apparently usable, but I haven't managed to set it up with any success personally. I, too, would be very happy to see it packaged with UnRaid — or at least available to integrate with a good tutorial — in the near future.
