I had posted last week about trying to get VNC working. I was never
successful nor were multiple admins. But we realized that all the hosts we
tried on were VMs. We followed the same procedure (
http://wiki.centos.org/HowTos/VNC-Server) on a machine with physical HW and
it worked with no problem. But on the VM I can connect, but I don't get any
window displayed. Here is what is in the log:

Anyone have any clues as to what could be wrong and why it works on a
physical host and not on a VM?
