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:


19/10/2013 07:14:27 PM [IPv6] Got connection from client
::ffff:10.250.151.75
19/10/2013 07:14:27 PM   other clients:
19/10/2013 07:14:27 PM Client Protocol Version 3.7
19/10/2013 07:14:27 PM Advertising security type 2
19/10/2013 07:14:28 PM Client returned security type 2

My xstartup file is identical on the VM and the physical host.

Does anyone out there have VNC working on a VM?
