Oct 17, 2021
Hi guys, proxmox 3 vm is available now. ubuntu, mac os big sur and windows 10. They are connected to 3 monitors and with GPU passthrough, I can take images from the monitors without any problems. I want to use Mouse and keyboard between VMs. What is the way to do this? I want to switch from ubuntu on my left screen to windows on my right screen or switch back to mac os.

I want to do the process in the following minutes of this video.
18:20 : 18:54

As the video appears, can copy paste between operating systems? How can he do this? There must be a way ?

thankyou for support.

Back then when Synergy was free I used that to work on different Linux + Win machines using one Mouse and Keyboard. You can try Barrier which is a free Fork of Synergy.

If you for example want to use barrier you need to install it to all of your guests that you want to use it for. Then setup barrier on all guests and one of your VMs will work as a server where you attach your mouse and keyboard. Your mouse/keyboard inputs are then send over the network to the clients.
