livemedia\-creator uses \fI\%Anaconda\fP,
|
|
\fI\%kickstart\fP and \fI\%Lorax\fP to create bootable media that use the
|
|
same install path as a normal system installation. It can be used to make live
|
|
isos, bootable (partitioned) disk images, tarfiles, and filesystem images for
|
|
use with virtualization and container solutions like libvirt, docker, and
|
|
OpenStack.
|
|
.sp
|
|
The general idea is to use qemu with kickstart and an Anaconda boot.iso to
|
|
install into a disk image and then use the disk image to create the bootable
|
|
media.
|
|
.sp
|
|
livemedia\-creator \-\-help will describe all of the options available. At the
|
|
minimum you need:
|
|
.sp
|
|
\fB\-\-make\-iso\fP to create a final bootable .iso or one of the other \fB\-\-make\-*\fP options.
|
|
.sp
|
|
\fB\-\-iso\fP to specify the Anaconda install media to use with qemu.
|
|
.sp
|
|
\fB\-\-ks\fP to select the kickstart file describing what to install.
|
|
.sp
|
|
To use livemedia\-creator with virtualization you will need to have qemu\-kvm installed.
|
|
.sp
|
|
If you are going to be using Anaconda directly, with \fB\-\-no\-virt\fP mode, make sure
|
|
you have the anaconda\-tui package installed.

You can observe the installation using vnc. The logs will show what port was
|
|
chosen, or you can use a specific port by passing it. eg. \fB\-\-vnc vnc:127.0.0.1:5\fP
|
|
.sp
|
|
This is usually a good idea when testing changes to the kickstart. lmc tries
|
|
to monitor the logs for fatal errors, but may not catch everything.
|
|
.SH HOW ISO CREATION WORKS
|
|
.sp
|
|
There are 2 stages, the install stage which produces a disk or filesystem image
|
|
as its output, and the boot media creation which uses the image as its input.
|
|
Normally you would run both stages, but it is possible to stop after the
|
|
install stage, by using \fB\-\-image\-only\fP, or to skip the install stage and use
|
|
a previously created disk image by passing \fB\-\-disk\-image\fP or \fB\-\-fs\-image\fP
|
|
.sp
|
|
When creating an iso qemu boots using the passed Anaconda installer iso
|
|
and installs the system based on the kickstart. The \fB%post\fP section of the
|
|
kickstart is used to customize the installed system in the same way that
|
|
current spin\-kickstarts do.
|
|
.sp
|
|
livemedia\-creator monitors the install process for problems by watching the
|
|
install logs. They are written to the current directory or to the base
|
|
directory specified by the \-\-logfile command. You can also monitor the install
|
|
by using a vnc client. This is recommended when first modifying a kickstart,
|
|
since there are still places where Anaconda may get stuck without the log
|
|
monitor catching it.
|
|
.sp
|
|
The output from this process is a partitioned disk image. kpartx can be used
|
|
to mount and examine it when there is a problem with the install. It can also
|
|
be booted using kvm.
|
|
.sp
|
|
When creating an iso the disk image\(aqs / partition is copied into a formatted
|
|
filesystem image which is then used as the input to lorax for creation of the
|
|
final media.
|
|
.sp
|
|
The final image is created by lorax, using the templates in /usr/share/lorax/live/
|
|
or the live directory below the directory specified by \fB\-\-lorax\-templates\fP\&. The
|
|
templates are written using the Mako template system with some extra commands
|
|
added by lorax.

|
The output from \-\-make\-iso includes the artifacts used to create the boot.iso;
|
|
the kernel, initrd, the squashfs filesystem, etc. If you only want the
|
|
boot.iso you can pass \fB\-\-iso\-only\fP and the other files will be removed. You
|
|
can also name the iso by using \fB\-\-iso\-name my\-live.iso\fP\&.

.SH KICKSTARTS
|
|
.sp
|
|
The docs/ directory includes several example kickstarts, one to create a live
|
|
desktop iso using GNOME, and another to create a minimal disk image. When
|
|
creating your own kickstarts you should start with the minimal example, it
|
|
includes several needed packages that are not always included by dependencies.
|
|
.sp
|
|
Or you can use existing spin kickstarts to create live media with a few
|
|
changes. Here are the steps I used to convert the Fedora XFCE spin.
|
|
.INDENT 0.0

|
.IP 1. 4
|
|
Flatten the xfce kickstart using ksflatten
|
|
.IP 2. 4
|
|
Add zerombr so you don\(aqt get the disk init dialog
|
|
.IP 3. 4
|
|
Add clearpart \-\-all
|
|
.IP 4. 4
|
|
Add swap partition
|
|
.IP 5. 4
|
|
bootloader target
|
|
.IP 6. 4
|
|
Add shutdown to the kickstart
|
|
.IP 7. 4
|
|
Add network \-\-bootproto=dhcp \-\-activate to activate the network
|
|
This works for F16 builds but for F15 and before you need to pass
|
|
something on the cmdline that activate the network, like sshd:

In the livesys script section of the %post remove the root password. This

really depends on how the spin wants to work. You could add the live user

One drawback to using qemu is that it pulls the packages from the repo each
|
|
time you run it. To speed things up you either need a local mirror of the
|
|
packages, or you can use a caching proxy. When using a proxy you pass it to
|
|
livemedia\-creator like this:
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|

\fB\-\-proxy=http://proxy.yourdomain.com:3128\fP
|
|
.UNINDENT
|
|
.UNINDENT

|
|
You also need to use a specific mirror instead of mirrormanager so that the
|
|
packages will get cached, so your kickstart url would look like:
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
\fBurl \-\-url="http://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/x86_64/os/"\fP

as well.

.SH ANACONDA IMAGE INSTALL (NO-VIRT)
|
|
.sp
|
|
You can create images without using qemu by passing \fB\-\-no\-virt\fP on the
|
|
cmdline. This will use Anaconda\(aqs directory install feature to handle the
|
|
install. There are a couple of things to keep in mind when doing this:
|
|
.INDENT 0.0
|
|
.IP 1. 3
|
|
It will be most reliable when building images for the same release that the
|
|
host is running. Because Anaconda has expectations about the system it is
|
|
running under you may encounter strange bugs if you try to build newer or
|
|
older releases.
|
|
.IP 2. 3
|
|
Make sure selinux is set to permissive or disabled. It won\(aqt install
|
|
correctly with selinux set to enforcing yet.
|
|
.IP 3. 3
|
|
It may totally trash your host. So far I haven\(aqt had this happen, but the
|
|
possibility exists that a bug in Anaconda could result in it operating on
|
|
real devices. I recommend running it in a virt or on a system that you can
|
|
afford to lose all data from.

Using no\-virt to create a partitioned disk image (eg. \-\-make\-disk or

.SH AMI IMAGES
|
|
.sp
|
|
Amazon EC2 images can be created by using the \-\-make\-ami switch and an appropriate
|
|
kickstart file. All of the work to customize the image is handled by the kickstart.
|
|
The example currently included was modified from the cloud\-kickstarts version so
|
|
that it would work with livemedia\-creator.
|
|
.sp

Example cmdline:
|
|
.sp

\fBsudo livemedia\-creator \-\-make\-ami \-\-iso=/path/to/boot.iso \-\-ks=./docs/fedora\-livemedia\-ec2.ks\fP
|
|
.sp
|

This will produce an ami\-root.img file in the working directory.
|
|
.sp
|

At this time I have not tested the image with EC2. Feedback would be welcome.
|
|
.SH APPLIANCE CREATION
|
|
.sp
|
|
livemedia\-creator can now replace appliance\-tools by using the \-\-make\-appliance
|
|
switch. This will create the partitioned disk image and an XML file that can be
|
|
used with virt\-image to setup a virtual system.
|
|
.sp
|
|
The XML is generated using the Mako template from
|
|
/usr/share/lorax/appliance/libvirt.xml You can use a different template by

|
passing \fB\-\-app\-template <template path>\fP
|

.SH OPEN CONTAINER INITIATIVE IMAGE CREATION
|
|
.sp
|
|
The OCI is a new specification that is still being worked on. You can read more about it at
|
|
\fI\%the Open Container Initiative website\fP\&. You can create
|
|
OCI images using the following command:
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
sudo livemedia\-creator \-\-make\-oci \-\-oci\-config /path/to/config.json \-\-oci\-runtime /path/to/runtime.json \e
|
|
\-\-iso=/path/to/boot.iso \-\-ks=/path/to/fedora\-minimal.ks
|
|
.ft P
|
|
.fi
|
|
.UNINDENT
|
|
.UNINDENT
|
|
.sp
|
|
You must provide the config.json and runtime.json files to be included in the bundle,
|
|
their specifications can be found \fI\%on the OCI github project\fP
|
|
output will be in the results directory with a default name of bundle.tar.xz
|
|
.sp
|
|
This will work with \fB\-\-no\-virt\fP and inside a mock since it doesn\(aqt use any
|
|
partitioned disk images.
|
|
.SH VAGRANT IMAGE CREATION
|
|
.sp
|
|
\fI\%Vagrant\fP images can be created using the following command:
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
sudo livemedia\-creator \-\-make\-vagrant \-\-vagrant\-metadata /path/to/metadata.json \e
|
|
\-\-iso=/path/to/boot.iso \-\-ks=/path/to/fedora\-vagrant.ks
|
|
.ft P
|
|
.fi
|
|
.UNINDENT
|
|
.UNINDENT
|
|
.sp
|
|
The image created is a \fI\%vagrant\-libvirt\fP provider image and needs to have
|
|
vagrant setup with libvirt before you can use it.
|
|
.sp
|
|
The \fB\-\-vagrant\-metadata\fP file is optional, it will create a minimal one by
|
|
default, and if one is passed it will make sure the disk size is setup
|
|
correctly. If you pass a \fB\-\-vagrant\-vagrantfile\fP it will be included in the
|
|
image verbatim. By default no vagrantfile is created.
|
|
.sp
|
|
There is an example Vagrant kickstart file in the docs directory that sets up
|
|
the vagrant user with the default insecure SSH pubkey and a few useful
|
|
utilities.
|
|
.sp
|
|
This also works with \fB\-\-no\-virt\fP, but will not work inside a mock due to its
|
|
use of partitioned disk images and qcow2.
|
|
.SH CREATING UEFI DISK IMAGES WITH VIRT
|
|
.sp
|
|
Partitioned disk images can only be created for the same platform as the host system (BIOS or
|
|
UEFI). You can use virt to create BIOS images on UEFI systems, and it is also possible
|
|
to create UEFI images on BIOS systems using OVMF. You first need to setup your system with
|
|
the OVMF firmware. The details can be \fI\%found here linux\-kvm OVMF page\fP
|
|
but it amounts to:
|
|
.INDENT 0.0
|
|
.IP 1. 3
|
|
Download the firmware.repo from \fI\%Gerd Hoffmann\fP and install it
|
|
in /etc/yum.repos.d/
|
|
.IP 2. 3
|
|
Install the edk2.git\-ovmf\-x64 package
|
|
.IP 3. 3
|
|
Copy /usr/share/edk2.git/ovmf\-x64/OVMF_CODE\-pure\-efi.fd to /usr/share/OVMF/OVMF_CODE.fd
|
|
.IP 4. 3
|
|
Copy /usr/share/edk2.git/ovmf\-x64/OVMF_VARS\-pure\-efi.fd to /usr/share/OVMF/OVMF_VARS.fd
|
|
.UNINDENT
|
|
.sp
|
|
Now you can run livemedia\-creator with \fB\-\-virt\-uefi\fP to boot and install using UEFI:
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
sudo livemedia\-creator \-\-make\-disk \-\-virt\-uefi \-\-iso=/path/to/boot.iso \e
|
|
\-\-ks=/path/to/fedora\-minimal.ks
|
|
.ft P
|
|
.fi
|
|
.UNINDENT
|
|
.UNINDENT
|
|
.sp
|
|
Make sure that the kickstart you are using creates a /boot/efi partition by including this:
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
part /boot/efi \-\-fstype="efi" \-\-size=500
|
|
.ft P
|
|
.fi
|
|
.UNINDENT
|
|
.UNINDENT
|
|
.sp
|
|
\fBNOTE:\fP
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
When using the resulting image with the current version of OVMF (edk2.git\-ovmf\-x64\-0\-20151103.b1295.ge5cffca)
|
|
it will not boot automatically because there is a problem with the fallback path.
|
|
You can boot it by entering the UEFI shell and running EFI/fedora/shim.efi and
|
|
then using efibootmgr to setup the correct boot entry.

.SH DEBUGGING PROBLEMS
|
|
.sp
|
|
Sometimes an installation will get stuck. When using qemu the logs will
|
|
be written to ./virt\-install.log and most of the time any problems that happen
|
|
will be near the end of the file. lmc tries to detect common errors and will
|
|
cancel the installation when they happen. But not everything can be caught.
|
|
When creating a new kickstart it is helpful to use vnc so that you can monitor
|
|
the installation as it happens, and if it gets stuck without lmc detecting the
|
|
problem you can switch to tty1 and examine the system directly.
|
|
.sp
|
|
If it does get stuck the best way to cancel is to use kill \-9 on the qemu pid,
|
|
lmc will detect that the process died and cleanup.
|
|
.sp
|
|
If lmc didn\(aqt handle the cleanup for some reason you can do this:
|
|
1. \fBsudo umount /tmp/lmc\-XXXX\fP to unmount the iso from its mountpoint.
|
|
2. \fBsudo rm \-rf /tmp/lmc\-XXXX\fP
|
|
3. \fBsudo rm /var/tmp/lmc\-disk\-XXXXX\fP to remove the disk image.
|
|
.sp
|
|
Note that lmc uses the lmc\- prefix for all of its temporary files and
|
|
directories to make it easier to find and clean up leftovers.
|
|
.sp
|
|
The logs from the qemu run are stored in virt\-install.log, logs from
|
|
livemedia\-creator are in livemedia.log and program.log
|
|
.sp
|
|
You can add \fB\-\-image\-only\fP to skip the .iso creation and examine the resulting
|
|
disk image. Or you can pass \fB\-\-keep\-image\fP to keep it around after the iso has
|
|
been created.
|
|
.sp
|
|
Cleaning up aborted \fB\-\-no\-virt\fP installs can sometimes be accomplished by
|
|
running the \fBanaconda\-cleanup\fP script. As of Fedora 18 anaconda is
|
|
multi\-threaded and it can sometimes become stuck and refuse to exit. When this
|
|
happens you can usually clean up by first killing the anaconda process then
|
|
running \fBanaconda\-cleanup\fP\&.
|
|
.SH HACKING
|
|
.sp
|
|
Development on this will take place as part of the lorax project, and on the
|
|
anaconda\-devel\-list mailing list, and \fI\%on github\fP
|
|
.sp
|
|
Feedback, enhancements and bugs are welcome. You can use \fI\%bugzilla\fP to
|
|
report bugs against the lorax component.
