/dev/kvm permission denied in vnc session

Question

How can I get virtualization (KVM) to work in non-local VNC sessions? I am getting a permission denied error, on /dev/kvm. Everything works outside of VNC fine. KVM is apparently required for android simulation.

Client Connection Info: This SHOULD NOT matter, other than it not being "localhost"... I think. I am connecting through VNC using the client, remmina, on a arm64 chromebook running cruiton with ubuntu 16.04. The VNC session was started using display 15 (vncserver :15).

terminal info from android studio:

$ studio.sh
Xlib:  extension "RANDR" missing on display ":15".

How do I fix this?

Solution

Using root for this is a bad idea. Add your user to the kvm group, logout (all sessions) and login and you should be fine.
