To save people some times :
Barrier seems to be an app meant to control multiple devices with the same mouse and keyboard. You need to install the software on all the machines for it to works.
You can then bind a keyboard shortcut to switch device. You can also bind it if you put your mouse at the and of a screen.

Edit: Input Leap looks like a promising KVM replacement for Barrier, thanks for sharing!
