AS a last addition.
I added this to my existing system too. It has many virtual machines.
I had the error " Starting VNC server: 2:root A VNC server is already 
running as :2"

after many reinstalls and many attempts and seeing 1,000s of posts from 
people freaking out, I took the initiative and thought that libvirt was 
conflicting. I changed the number to 8 in the /sysconfig/vncserver 
file....and then it worked easily.

Not sure what will happen if you select 2, 3, etc....and then add some 
virtual machines. I see conflicts ahead.
