And we have a VM that when you start it says its Connecting to console 
for guest.  But the console message just stays like that and yet the 
machine completely boots up and we can log into it remotely in a 
terminal window.  We just cannot get a console screen.

We've tried putting the vnc on different ports 5901,5902,5903,etc.  But 
it doesn't help.   Again, what can we do to fix these problems?  Thanks.
