xen-list-images
XEN-LIST-IMAGES(8) Perl Programmers Reference Guide XEN-LIST-IMAGES(8)
NAME
xen-list-images - List all the created and configured Xen images.
SYNOPSIS
xen-list-image [options]
Help Options:
--help Show this scripts help information.
--manual Read this scripts manual.
--version Show the version number and exit.
Testing options:
--test Specify an alternate Xen configuration directory.
OPTIONS
--help Show the scripts help information.
--manual Read the manual.
--test This flag causes the script to load the Xen configuration files from a different directory than the default of /etc/xen.
--version Show the version number and exit.
DESCRIPTION
xen-list-images is a simple script which will display all the
Xen images which have been created.
This works by iterating over all files matching the pattern
/etc/xen/*.cfg which is what the xen-create-image script would
create.
For each instance which has been created we'll display the name,
and then either the IP address configured, or "DHCP" to denote
a dynamic host.
TODO
It should be possible to determine the disk(s) used by the images,
and then display their sizes.
