1) What are the permissions of the device node mentioned in my previous
response?

2) Does the groups command show that you're in the group right now?

Of course. You've asked it to couple the display with its embedded VNC 
server. You'll need to connect with a VNC client to see it.

The parameters you used look fine. Display ":0" should translate to TCP 
port 5900, meaning that qemu should be listening on port 5900. You can 
check with netstat or ss.

Assuming both server and client are run locally, connecting to either 
"localhost:0" or "localhost:5900" should work.
