How would one use looking glass to switch between VMs (that are using GPU passthrough) if you want to use only 1 display and 1 keyboard? I would like to be able to switch between VMs using the keyboard without any noticeable latency.
I was thinking this would be more of an “extra hardware” application - where you plug in your GPUs outputs into another card, which has some OS software to switch between them and is connected to only one display. However, I have heard about SR-IOV, but haven’t researched it yet.
Thoughts on the optimal method for this?
