To use the VNC viewer from a remote computer, the firewall must permit access to as
many ports as VM Guest systems run from port 5900 and up. For example, if you want
to run 10 VM Guest systems, you will have to open the tcp ports 5900:5910.
In addition to this, change
vnc-listen
in
/etc/xen/xend-config.sxp
to
open the access to the VM Guest. For more information about modifying
xend-config.sxp
see
Section 4.2, “Controlling the Host by Modifying xend Set-
tings”
(page 32).
To access the virtual machine from the local console running a VNC viewer client,
enter one of the following commands:
•
vncviewer ::590#
•
vncviewer :#
#
is the VNC viewer port number assigned to the virtual machine.
When accessing the VM Guest from a machine other than Domain0, use the following
syntax:
vncviewer 192.168.3.100::590#
In this case, the IP address of Domain0 is 192.168.3.100.
If you are using the java VNC server, use
580#
as the port number, where
#
is the
VNC viewer port number assigned to the virtual machine.
