This is what I see on my Dom0:
server:/etc # netstat -lpdn | grep 590

There are a couple of points worth mentioning about the information displayed.

As of SLES11 VNC does not, by default, have access to Display 0.
See TID 7003097 Enabling VNC Server on startup of the X server with SLE 11.
I have implemented the changes in this TID and that is likely why 7620/X is listening on port 5900. I use SSH/VNC for remote access and need access to Display 0 as soon as the server has rebooted.

In /etc/xinetd.d/vnc I have enable port 5902 which is why 6880/xinetd is listening on 5902.

It would appear that my DomU's have been assigned ports sequentially from 5900 as long as they are not already used.

I don't know why VNC is not working for you. Do you think TID 7003097 might help?
