graphical interface for changing the name also contains an extra description line, that
may be used to add a single line of text.
When using the Xen configuration files in
/etc/xen/vm
, the syntax for setting the
description looks like this:
description="Responsible: tux@example.com"
It is also possible to change the SXP configuration to add or change the description as
described in Section 5.3, “Configuring a Virtual Machine by Modifying its Xend Set-
tings” (page 37). The description is added directly below the
domain
element and
looks like this:
(domain
...
(description 'Responsible: tux@example.com')

To retrieve the description of a specific VM Guest, for example, a guest with the name
alice, run the command:
xm list -l alice | grep description
9.7 Providing Host Information for
VM Guest Systems
In a standard Xen environment, the VM Guest systems have only very limited informa-
tion about the VM Host Server system they are running on. If a guest should know
more about the VM Host Server it runs on,
vhostmd
can provide more information
to selected guests. To set up your system to run
vhostmd
, proceed as follows:
1 Install the package vhostmd on the VM Host Server.
2
Edit the file
/etc/vhostmd/vhostmd.conf
if you want to add or remove
metric
sections from the configuration. However, the default works well.
3
Check the validity of the
vhostmd.conf
configuration file with the command:
cd /etc/vhostmd
xmllint --postvalid --noout vhostmd.conf
