XenServer Virtual Machine Installation Guide Installing Linux VMs 28
Setting up Debian Etch VMs for VNC
The built-in Debian Etch template comes pre-configured with VNC set up and ready use. However, the
default VNC configuration in Debian does not permit the root administrator to log in by default. To log in
through VNC, you can either:
• Log in to the text console and create a new, unprivileged user by running the adduser command. This
is the recommended course of action.
• At the graphical console login prompt, select Actions, Configure the Login Manager, type in your root
password, then select Security, Allow local system administrator login, and finally select Close.
If you need to reset the VNC password, run the command:
vnc4passwd /etc/vncpass
Checking runlevels
Red Hat and SUSE Linux VMs use runlevel 5 for graphical startup. This section describes how to verify that
your VM is configured to start up in runlevel 5 and how to change it if it is not.
1. Check /etc/inittab to see what the default runlevel is set to. Look for the line that reads:
id:n:initdefault:
If n is not 5, edit the file to make it so.
2. You can run the command telinit q ; telinit 5 after this change to avoid having to actually reboot to
switch runlevels.
Release Notes
Most modern Linux distributions support Xen paravirtualization directly, but have different installation mech-
anisms and some kernel limitations.
Debian Lenny 5.0
XenServer support for Debian Lenny makes use of support from the distribution to perform an installation
into a virtual machine, in a similar manner to the other supported Linux distributions. This provides a more
customizable configuration and native support for automation of the installation, and so on. Making use of
these features is documented later in this guide. However this does mean that, unlike Debian Etch, some
configuration of VNC may have to be done manually if you want a graphical console.
Note
Network installation support is provided by the distribution so HTTP and FTP installation is supported.
Installation from a CD or DVD is also supported. Only 32-bit Debian Lenny is supported due to the up-
stream limitations.
