Usage $this ACTION XENGUEST [ARGS]
Where XENGUEST is a xenguest image file or a xenguest directory.
The following actions are supported:
help Display this help
create Create a xenguest image
update Update/modify a xenguest image
partial Create partial xenguest image in a directory
pack Pack a xenguest directory into an image
check Check a xenguest image
dump-paramsconfig Display the guest configuration of a xenguest image
dump-xenconfig Display the xen configuration of a xenguest image
dump-diskconfig Display the disk configuration of a xenguest image
dump-init Display init scripts of a xenguest image
extract Extract a xenguest image content
extract-config Extract the guest configuration from a xenguest image
extract-disk-file Extract a disk file from a xenguest image
Use $this ACTION --help to have help on a specific action and its arguments.
EOF
}
usage-check() {
cat <<EOF
Usage $this check XENGUEST
Check a xenguest image or a xenguest directory.
EOF
}
usage-update-create() {
cat <<EOF
All arguments are handled in order.
Global configuration for the guest
--guest-config-reset reset guest global configuration
--set-param=PARAM disable parameter PARAM in guest global configuration
--set-param=PARAM=VAL set parameter PARAM to value VAL in guest global
configuration.
Example of parameters supported are:
GUEST_AUTOBOOT: if set to 1 (default), guest will be
automatically created and started during host init.
Xen configuration for the guest
--xen-reset-config reset xen guest configuration to default
--xen-name= disable name parameter in xen configuration
--xen-name=NAME set guest name in xen configuration
--xen-kernel= disable guest kernel parameter in xen configuration
--xen-kernel=FILE set guest kernel to FILE (file is added and xen
configuration is set to use it)
--xen-memory set guest memory size (in MB)
--xen-vcpus set guest number of virtual cpus
--xen-clean-extra set guest command line (extra) to an empty string
--xen-extra=ARG append ARG to the guest command line (with space)
use this several time to set command line.
To set the command line to "console=ttyS0 rw" do
--xen-extra=console=ttyS0 --xen-extra=rw
--xen-root= disable root parameter in xen configuration
--xen-root=ROOT set guest root in xen configuration
--xen-device-tree= disable device tree parameter in xen configuration
--xen-device-tree=FILE set guest device tree in xen configuration and add
file to xen files
--xen-disk= disable disk parameter in xen configuration
--xen-disk=DEV set guest disk to device DEV (phy:DEV,xvda,w is set)
--xen-append=FILE append FILE content to xen configuration
Xen files
--xen-add-file=SRC:DST add file SRC as file DST in the xenguest image.
If DST already exist in the image, it is overwritten.
DST must be the same as arguments passed to other
options (like --xen-kernel)
--xen-rm-file=DST remove file DST from the xenguest image.
Init configuration
This can be used to add init scripts for the guest. There are 3 possible init
scripts which are called at different time. The pre scripts are called first,
then the xen guest is created in pause and standard init scripts are called.
Finally the xen guest is started then the post init scripts are called.
Each script is called with the name of the guest as first argument and
multiple scripts can be added (they must have different names).
--init-script=FILE add FILE as init script
--init-pre=FILE add FILE as pre init script
--init-post=FILE add FILE as post init script
Disk configuration
--disk-reset-config reset disk guest configuration to default (no disk)
--disk-size=SZ set guest disk size (in GB)
--disk-device=DEV set device to be used to create the guest disk
if unset or set to an empty string, the volume will be
create in the default manager volume group.
--disk-add-part=DEF add a partition to the guest disk with definition DEF
a partition definition must have the following format:
ID:SIZE:FORMAT:CONTENT where:
- ID is the partition numeric ID (1 to 4)
- FORMAT is the filesystem format (supported formats
are none, vfat, swap, ext2, ext3 and ext4) or can be
left empty to not format
- CONTENT can be used to point to a file added using
--disk-add-file to be used as partition initial
content (tar file or img file)
--disk-rm-part=ID remove partition ID from the guest disk
--disk-add-file=SRC:DST add file SRC as disk file DST in the xenguest image.
DST can then be used as a partition CONTENT.
--disk--rm-file=DST remove disk file DST from the xenguest image.
