-i5 6500 

-asus b250m plus 

-16gb 2133Mhz ram

-1x gtx950 2gb 

-550 Watt psu 

-Thermaltake TT eSPORTS Challenger DUO RGB USB Gaming Keyboard and Mouse Combo for player 1 

- random stuff for player 2 

 

-Would this configuration work?

-would the host system(ubuntu) detect mouse and keyboard movement from the mouse % keyboard that is passthrough to the vm and do random stuff 

-if i shut down the vm how can i turn it back on or do i have to do it via virtmanager
