DESCRIPTION

	 xen-delete-image is a simple script which allows you to delete
	Xen instances which have previously been created by xen-create-image.

	 You must be root to run this script as it removes the Xen configuration
	file from /etc/xen and potentially removes LVM and EVMS volumes.

	 (When invoked with the '--test' flag the script will continue running,
	but will fail to remove anything which the user does not have permission
	to delete.)

LOOPBACK EXAMPLE

	 Assuming that you have three images 'foo', 'bar', and 'baz', stored
	beneath /home/xen the first two may be deleted via:

	   xen-delete-image --dir=/home/xen foo bar

	 You may also delete them by running:

	   xen-delete-image --dir=/home/xen --hostname=foo --hostname=bar

	 (The matching Xen configuration files beneath /etc/xen will also be
	removed.)

LVM EXAMPLE

	 Assuming that you have the volume group 'skx-vol' containing three
	Xen instances 'foo', 'bar', and 'baz' the first two may be deleted via:

	   xen-delete-image --lvm=skx-vol foo bar

	 This will remove the volumes 'foo-disk', 'foo-swap', 'bar-disk',
	and 'bar-swap'.

	 Note that if the images were created with "--noswap" then the swap
	volumes will not be present, so will not need to be deleted.

	 The Xen configuration files will also be removed from beneath /etc/xen.

EVMS EXAMPLE

	 Assuming that you have the container 'mycontainer' containing three
	Xen instances 'foo', 'bar', and 'baz' the first two may be deleted via:

	   xen-delete-image --evms=lvm2/mycontainer --hostname=foo --hostname=bar

	 This will remove the volumes 'foo-disk', 'foo-swap', 'bar-disk',
	and 'bar-swap'.

	 Note that if the images were created with "--noswap" then the swap
	volumes will not be present, so will not need to be deleted.

	 The Xen configuration files will also be removed.
