    So it seems that for GPU passthrough, one must actually have each GPU wired to the monitor (versus one GPU wired to it, and using a bridge between the two GPUs, like SLI or Crossfire), correct? Therefore, when switching to the workspace that has the guest OS with its own GPU, one will either need to have a 2nd monitor or have two GPUs hooked up to one monitor, correct? When I had a guest VM of windows without GPU passthrough on a Linux host, for example, then I could flip between them seamlessly and quickly as if they were two WM workspaces... Is there any clever way to have this same seamless switching while using GPU passthrough (on one monitor)?
    Thanks!

    there is a project called 'looking-glass' which uses display mirroring and guest/host memory sharing for displaying a guest display on the host via a client program
    see https://looking-glass.hostfission.com/

    other than that, you could use some kind of screen sharing technology (rdp,vnc,...)

    I'm thinking if they're both (guest and host) wired to the monitor through different GPUs... Then I'll see how quickly I can get the monitor to switch sources via some kind of remote. Might introduce too much latency.

    The looking glass project only supports windows and pro GPUs it seems. Doesn't seem like it'll be ready for a while.
