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:

Googling that error I found this: https://bbs.archlinux.org/viewtopic.php?id=63576 and I followed the advice there. Now I don't get that error, but I still get no display. Now all I get in the log is this:

My xstartup file is identical on the VM and the physical host.
Does anyone out there have VNC working on a VM?

Anyone have any clues as to what could be wrong and why it works on a physical host and not on a VM?
I believe that I just find the answer for this question. I have been beating up myself for the last few hours and I was getting the same error that you posted.
****************Test Environment************** 2 Laptops 1 of the two laptop has several linux KVMs
**********************************************
The reason why you are not able to connect with the KVM Guest is because by default KVM Guest uses VNC, which will conflict with tiger-vncserver.
What is your current VM environment, to resolved the issue I switch from VNC to spice for the choice of display for the KVM Guest and I was finally able to establish communication with the KVM guest.
Let me know if this works for you.
