RE: [Xen-users] Controlling VNC console port

["Dustin Henning" <Dustin.Henning@xxxxxxxxxxx>]

        Here are the vnc lines from one of my domUs.  This is in a python
file (/etc/xen/xmexample.hvm).  I don't know how it would be set up in a xml
config file.

#---------------------------------------------------------------------------
-
# enable VNC library for graphics, default = 1
vnc=1

#---------------------------------------------------------------------------
-
# address that should be listened on for the VNC server if vnc is set.
# default is to use 'vnc-listen' setting from /etc/xen/xend-config.sxp
#vnclisten="127.0.0.1"

#---------------------------------------------------------------------------
-
# set VNC display number, default = domid
vncdisplay=1

#---------------------------------------------------------------------------
-
# try to find an unused port for the VNC server, default = 1
vncunused=0

#---------------------------------------------------------------------------
-
# enable spawning vncviewer for domain's console
# (only valid when vnc=1), default = 0
#vncconsole=1

        I believe the included text from xmexample.hvm is self-explanatory
enough, but you need to know that vncdisplay=1 chooses port 5901.  Hope this
helps.

Subject: [Xen-users] Controlling VNC console port

I can't find a way to *control* what port a VNC console for a domU is on.
There's a vncport param to virt-install, but it doesn't seem to do
anything. There doesn't seem to be a parameter in the config files in
/etc/xen at all.

Maybe I can control where dom0 VNC ports appear, though my tests give
inconsistent results.

I need these to be in stable places because they're going to be on systems
in a cluster hidden behind a load-balancer, so I need to set up ssh
tunnels on the load-balancer to allow outside connections to the system
consoles (particularly key for the windows servers in the cluster, but
desirable for all of them).  So that the windows people responsible for
software maintenance on the windows servers don't have to learn Linux and
Xen just to get to the console of their Windows box!
