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 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:

.SS Using a Proxy with repos
|
|
.sp
|
|
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
|
|
.sp
|
|
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
|

.UNINDENT
|
|
.UNINDENT

|
|
You can also add an update repo, but don\(aqt name it updates. Add \-\-proxy to it
|
|
as well. You can use all of the \fI\%kickstart commands\fP in your kickstart. Make sure there
|
|
is only one \fBurl\fP command, other repos have to use the \fBrepo\fP command and cannot be
|
|
named \fBupdates\fP which is reserved for Anaconda\(aqs use. eg.:
|

.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.

The logs from anaconda will be placed in an ./anaconda/ directory in either

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
|

Import the resulting disk image into the OpenStack system, either via the web UI, or glance on the cmdline:

If qcow2 wasn\(aqt used then \fB\-\-disk\-format\fP should be set to raw.

.SH DOCKER IMAGE CREATION
|
|
.sp
|
|
Use lmc to create a tarfile as described in the \fI\%TAR File Creation\fP section, but substitute the
|
|
fedora\-docker.ks example kickstart which removes the requirement for core files and the kernel.
|
|
.sp
|
|
You can then import the tarfile into docker like this (as root):
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
\fBcat /var/tmp/fedora\-root.tar.xz | docker import \- fedora\-root\fP
|

.UNINDENT

And then run bash inside of it:

.INDENT 3.5
|

\fBsudo docker run \-i \-t fedora\-root /bin/bash\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 you suspect problems with %pre or %post sections you can redirect the output
|
|
to the terminal and examine it by logging into the VM. eg.:
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
%pre
|
|
chvt
|
|
exec < /dev/tty3 > /dev/tty3 2>/dev/tty3
|
|
#do stuff
|
|
echo hello world
|
|
%end
|
|
.ft P
|
|
.fi
|
|
.UNINDENT
|
|
.UNINDENT
|
|
.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.
