To get the performance benefits the VM can't be run with a spice / vnc interface, so there is no virtual screen or virtual input. You have to pass the VM its GPU and some USB ports and can only see/interact through those and the network bridge. My keyboard and mouse can pair to multiple different machines at the same time and switch with a button press so I just do that. Synergy also works fine, you just need to temporarily pass a real keyboard in to set it up. There is also a newish feature in QEMU that allows they physical devices to be swapped back and forward by pressing both CTRL keys [1]. It works reasonably well with a few quirks (Extra mouse buttons dont work in guest, for example) Same thing apples to the screen, I surrender an entire monitor to whatever VM is running, but you could use a KVM switch. It's a little work to get set up and tuned but it is 100% a dual boot killer. The next time I reconfigure this machine, I won't be installing a native Windows partition, I simply don't need it anymore.
