Hi all.  In my CentOS 5.1 domUs, I add the following to the config file:

vfb = [ 'type=vnc,vnclisten=0.0.0.0,vncdisplay=1,vncpasswd=somepass' ]

at which point console output will default to vnc (assuming I remove
the "console=xvc0" argument from the kernel line in grub).  To enable
interactive logon I'd just add another line into /etc/inittab for the
vnc console.  On Debian Etch (2.6.18-4-xen-686) I'm trying to
accomplish the same thing but without any success.  When I launch the
domU and hit the VNC server, it simply says "parallel0 console" but
does not output anything else.  I've tried poking around in /dev and
it does not appear that the vfb gets a separate device as it would
under CentOS.  Google is also not very helpful in this regard, the
only thing remotely relevant (which doesn't solve my problem) is
http://lists.xensource.com/archives/html/xen-users/2008-04/msg00686.html.
 dom0 is Cent 5.1 with Xen 3.2.1 compiled from source.

Any idea what I should be doing to get debian to work?  And on a
related note, Ubuntu 7.10 appears to do what I want by default (I
haven't tested it yet - I gather that from google), but is there
anything I should know about for Ubuntu 7.04?

-Ray
