I know spice is used by virt-manager to control virtual machines. Can I use SPICE to do the same thing but over a fast 5ghz local network? I want to control the machine on the other room but I need it to be really fast, so VNC is out of question.
Reading the spice downloads page there are lots of servers and clients, I'm lost. How can I make SPICE work like VNC? Can I also plug USB things in one computer and use them in another?
How can I remote control my hardware Ubuntu desktop with spice, instead of vnc? has no answers
UPDATE: the intent is to use it with virtual machines in a server on the room
This is probably ok for a comment, but being too long, I post it as an answer.
A long time ago, I recall dealing with a Spice server in Ubuntu. I am now looking for a few sources that you may check.
This is one I remember reading http://learn.linksprite.com/pcduino/desktop-visualization/install-spice-server-on-a-ubuntu-12-04-server-and-create-virtual-machine-to-be-used-with-pcduino3s-as-client/
These are others, with a varying degree of relevance. Some are related to Spice as a client.
