Think about a classroom equiped with a linux-KVM server and some tiny PCs (Raspbery Pis, Odroid, and such).
I would like to control a desktop VM on the linux-KVM server from a tiny client with screen, mouse and keyboard.
But I want to do it without installing X on the clients, to keep them as light as possible. Some applications can output full hd video, use mouse, keyboard and network, all without X. Xbmc or RetroArch can. So why not a VNC client ?
Is it only possible ? Does any software allows that ?
