[Fedora-xen] ID = VNC Port

[Juerg Ritter]

Hi Daniel

Thanks for your suggestions, I will test that out. I am working on a
solution for a RHEL5 environment actually, and as far as i know, this
virt-viewer is not part of RHEL5. I think I will find a solution that
will work. Probably virsh dumpxml <vmname> gives me some helpful
information which can be included into my script.

Many thanks for your help!

regards, Juerg
