[one-users] vnc port in onemc

[Rogier Mars]

Hi,

I've made some quick changes to ONEMC to show the VNC port in the  
interface. I've updated the template that onemc creates with a  
GRAPHICS section, enabling vnc on the quest.

As a workaround until ONE can use the VMID in the graphics section, I  
use a virsh command to get the vncport. To get this working the  
webserver user should be allowed to execute the virsh command via  
sudo. Add the following to sudoers:
apache     ALL=(ALL)       NOPASSWD: /usr/bin/virsh *

Also I encountered some problems with the model section in the KVM  
template so I commented that out as well.

Cheers,

rogier
