<p>livemedia-creator uses <a class="reference external" href="https://github.com/rhinstaller/anaconda">Anaconda</a>,
<a class="reference external" href="https://github.com/rhinstaller/pykickstart">kickstart</a> and <a class="reference external" href="https://github.com/rhinstaller/lorax">Lorax</a> 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.</p>
<p>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.</p>
<p>livemedia-creator --help will describe all of the options available. At the
minimum you need:</p>
<p><code class="docutils literal notranslate"><span class="pre">--make-iso</span></code> to create a final bootable .iso or one of the other <code class="docutils literal notranslate"><span class="pre">--make-*</span></code> options.</p>
<p><code class="docutils literal notranslate"><span class="pre">--iso</span></code> to specify the Anaconda install media to use with qemu.</p>
<p><code class="docutils literal notranslate"><span class="pre">--ks</span></code> to select the kickstart file describing what to install.</p>
<p>To use livemedia-creator with virtualization you will need to have qemu installed.</p>
<p>If you are going to be using Anaconda directly, with <code class="docutils literal notranslate"><span class="pre">--no-virt</span></code> mode, make sure
you have the anaconda-tui package installed.</p>
<p>Conventions used in this document:</p>
<p><code class="docutils literal notranslate"><span class="pre">lmc</span></code> is an abbreviation for livemedia-creator.</p>
<p><code class="docutils literal notranslate"><span class="pre">builder</span></code> is the system where livemedia-creator is being run</p>
<p><code class="docutils literal notranslate"><span class="pre">image</span></code> is the disk image being created by running livemedia-creator</p>

</div>
<p>You can run it directly from the lorax git repo like this:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>sudo PATH=./src/sbin/:$PATH PYTHONPATH=./src/ ./src/sbin/livemedia-creator \
--make-iso --iso=/extra/iso/boot.iso \
--ks=./docs/fedora-livemedia.ks --lorax-templates=./share/
</pre></div>
</div>
<p>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. <code class="docutils literal notranslate"><span class="pre">--vnc</span> <span class="pre">vnc:127.0.0.1:5</span></code></p>
<p>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.</p>
</section>
<section id="how-iso-creation-works">
<h2>How ISO creation works<a class="headerlink" href="#how-iso-creation-works" title="Permalink to this headline"></a></h2>
<p>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 <code class="docutils literal notranslate"><span class="pre">--image-only</span></code>, or to skip the install stage and use
a previously created disk image by passing <code class="docutils literal notranslate"><span class="pre">--disk-image</span></code> or <code class="docutils literal notranslate"><span class="pre">--fs-image</span></code></p>
<p>When creating an iso qemu boots using the passed Anaconda installer iso
and installs the system based on the kickstart. The <code class="docutils literal notranslate"><span class="pre">%post</span></code> section of the
kickstart is used to customize the installed system in the same way that
current spin-kickstarts do.</p>
<p>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.</p>
<p>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.</p>
<p>When creating an iso the disk image's / partition is copied into a formatted
filesystem image which is then used as the input to lorax for creation of the
final media.</p>
<p>The final image is created by lorax, using the templates in /usr/share/lorax/live/
or the live directory below the directory specified by <code class="docutils literal notranslate"><span class="pre">--lorax-templates</span></code>. The
templates are written using the Mako template system with some extra commands
added by lorax.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>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 <code class="docutils literal notranslate"><span class="pre">--iso-only</span></code> and the other files will be removed. You
can also name the iso by using <code class="docutils literal notranslate"><span class="pre">--iso-name</span> <span class="pre">my-live.iso</span></code>.</p>

<section id="kickstarts">
<h2>Kickstarts<a class="headerlink" href="#kickstarts" title="Permalink to this headline"></a></h2>
<p>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.</p>
<p>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.</p>
<ol class="arabic">
<li><p>Flatten the xfce kickstart using ksflatten</p></li>
<li><p>Add zerombr so you don't get the disk init dialog</p></li>
<li><p>Add clearpart --all</p></li>
<li><p>Add swap partition</p></li>
<li><p>bootloader target</p></li>
<li><p>Add shutdown to the kickstart</p></li>
<li><p>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:</p>
<blockquote>
<div><p><code class="docutils literal notranslate"><span class="pre">livemedia-creator</span> <span class="pre">--kernel-args=&quot;sshd&quot;</span></code></p>
</div></blockquote>
</li>
<li><p>Add a root password:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">rootpw</span> <span class="n">rootme</span>
<span class="n">network</span> <span class="o">--</span><span class="n">bootproto</span><span class="o">=</span><span class="n">dhcp</span> <span class="o">--</span><span class="n">activate</span>
<span class="n">zerombr</span>
<span class="n">clearpart</span> <span class="o">--</span><span class="nb">all</span>

<span class="n">shutdown</span>
</pre></div>
</div>
</li>
<li><p>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
that you create to the %wheel group so that sudo works if you wanted to.</p>
<blockquote>
<div><p><code class="docutils literal notranslate"><span class="pre">passwd</span> <span class="pre">-d</span> <span class="pre">root</span> <span class="pre">&gt;</span> <span class="pre">/dev/null</span></code></p>
</div></blockquote>
</li>
<li><p>Remove /etc/fstab in %post, dracut handles mounting the rootfs</p>
<p><code class="docutils literal notranslate"><span class="pre">cat</span> <span class="pre">/dev/null</span> <span class="pre">&gt;</span> <span class="pre">/dev/fstab</span></code></p>
<p>Do this only for live iso's, the filesystem will be mounted read only if
there is no /etc/fstab</p>
</li>
<li><p>Don't delete initramfs files from /boot in %post</p></li>
<li><p>When creating live iso's you need to have, at least, these packages in the %package section::
dracut-config-generic
dracut-live
-dracut-config-rescue
grub2-efi
syslinux</p></li>

<section id="using-a-proxy-with-repos">
<h3>Using a Proxy with repos<a class="headerlink" href="#using-a-proxy-with-repos" title="Permalink to this headline"></a></h3>
<p>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:</p>
<blockquote>
<div><p><code class="docutils literal notranslate"><span class="pre">--proxy=http://proxy.yourdomain.com:3128</span></code></p>
</div></blockquote>
<p>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:</p>
<blockquote>
<div><p><code class="docutils literal notranslate"><span class="pre">url</span> <span class="pre">--url=&quot;http://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/x86_64/os/&quot;</span></code></p>
</div></blockquote>
<p>You can also add an update repo, but don't name it updates. Add --proxy to it
as well. You can use all of the <a class="reference external" href="https://pykickstart.readthedocs.io/en/latest/kickstart-docs.html#chapter-2-kickstart-commands-in-fedora">kickstart commands</a> in your kickstart. Make sure there
is only one <code class="docutils literal notranslate"><span class="pre">url</span></code> command, other repos have to use the <code class="docutils literal notranslate"><span class="pre">repo</span></code> command and cannot be
named <code class="docutils literal notranslate"><span class="pre">updates</span></code> which is reserved for Anaconda's use. eg.:</p>

<section id="anaconda-image-install-no-virt">
<h2>Anaconda image install (no-virt)<a class="headerlink" href="#anaconda-image-install-no-virt" title="Permalink to this headline"></a></h2>
<p>You can create images without using qemu by passing <code class="docutils literal notranslate"><span class="pre">--no-virt</span></code> on the
cmdline. This will use Anaconda's directory install feature to handle the
install. There are a couple of things to keep in mind when doing this:</p>
<ol class="arabic simple">
<li><p>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.</p></li>
<li><p>It may totally trash your host. So far I haven't 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.</p></li>
</ol>
<p>The logs from anaconda will be placed in an ./anaconda/ directory in either
the current directory or in the directory used for --logfile</p>
<p>Example cmdline:</p>
<p><code class="docutils literal notranslate"><span class="pre">sudo</span> <span class="pre">livemedia-creator</span> <span class="pre">--make-iso</span> <span class="pre">--no-virt</span> <span class="pre">--ks=./fedora-livemedia.ks</span></code></p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>Using no-virt to create a partitioned disk image (eg. --make-disk or
--make-vagrant) will only create disks usable on the host platform (BIOS
or UEFI). You can create BIOS partitioned disk images on UEFI by using
virt.</p>
</div>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>As of version 30.7 SELinux can be set to Enforcing. The current state is
logged for debugging purposes and if there are SELinux denials they should
be reported as a bug.</p>

<h2>AMI Images<a class="headerlink" href="#ami-images" title="Permalink to this headline"></a></h2>
<p>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.</p>
<p>Example cmdline:</p>
<p><code class="docutils literal notranslate"><span class="pre">sudo</span> <span class="pre">livemedia-creator</span> <span class="pre">--make-ami</span> <span class="pre">--iso=/path/to/boot.iso</span> <span class="pre">--ks=./docs/fedora-livemedia-ec2.ks</span></code></p>

<h2>Appliance Creation<a class="headerlink" href="#appliance-creation" title="Permalink to this headline"></a></h2>
<p>livemedia-creator can now replace appliance-tools by using the --make-appliance

<p>livemedia-creator can be used to create un-partitined filesystem images using
the <code class="docutils literal notranslate"><span class="pre">--make-fsimage</span></code> option. As of version 21.8 this works with both qemu and
no-virt modes of operation. Previously it was only available with no-virt.</p>
<p>Kickstarts should have a single / partition with no extra mountpoints.</p>

<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">sudo</span> <span class="n">livemedia</span><span class="o">-</span><span class="n">creator</span> <span class="o">--</span><span class="n">make</span><span class="o">-</span><span class="n">vagrant</span> <span class="o">--</span><span class="n">vagrant</span><span class="o">-</span><span class="n">metadata</span> <span class="o">/</span><span class="n">path</span><span class="o">/</span><span class="n">to</span><span class="o">/</span><span class="n">metadata</span><span class="o">.</span><span class="n">json</span> \
<span class="o">--</span><span class="n">iso</span><span class="o">=/</span><span class="n">path</span><span class="o">/</span><span class="n">to</span><span class="o">/</span><span class="n">boot</span><span class="o">.</span><span class="n">iso</span> <span class="o">--</span><span class="n">ks</span><span class="o">=/</span><span class="n">path</span><span class="o">/</span><span class="n">to</span><span class="o">/</span><span class="n">fedora</span><span class="o">-</span><span class="n">vagrant</span><span class="o">.</span><span class="n">ks</span>
</pre></div>
</div>
<p>The image created is a <a class="reference external" href="https://github.com/pradels/vagrant-libvirt">vagrant-libvirt</a> provider image and needs to have
vagrant setup with libvirt before you can use it.</p>
<p>The <code class="docutils literal notranslate"><span class="pre">--vagrant-metadata</span></code> 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 <code class="docutils literal notranslate"><span class="pre">--vagrant-vagrantfile</span></code> it will be included in the
image verbatim. By default no vagrantfile is created.</p>
<p>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.</p>
<p>This also works with <code class="docutils literal notranslate"><span class="pre">--no-virt</span></code>, but will not work inside a mock due to its
use of partitioned disk images and qcow2.</p>

<h2>Creating UEFI disk images with virt<a class="headerlink" href="#creating-uefi-disk-images-with-virt" title="Permalink to this headline"></a></h2>
<p>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 firmware and qemu.</p>
<p>Install the lorax-lmc-virt package, this will install qemu and the OVMF
firmware files.</p>
<p>Now you can run livemedia-creator with <code class="docutils literal notranslate"><span class="pre">--virt-uefi</span></code> to boot and install using UEFI:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">sudo</span> <span class="n">livemedia</span><span class="o">-</span><span class="n">creator</span> <span class="o">--</span><span class="n">make</span><span class="o">-</span><span class="n">disk</span> <span class="o">--</span><span class="n">virt</span><span class="o">-</span><span class="n">uefi</span> <span class="o">--</span><span class="n">iso</span><span class="o">=/</span><span class="n">path</span><span class="o">/</span><span class="n">to</span><span class="o">/</span><span class="n">boot</span><span class="o">.</span><span class="n">iso</span> \
<span class="o">--</span><span class="n">ks</span><span class="o">=/</span><span class="n">path</span><span class="o">/</span><span class="n">to</span><span class="o">/</span><span class="n">fedora</span><span class="o">-</span><span class="n">minimal</span><span class="o">.</span><span class="n">ks</span>
</pre></div>
</div>
<p>Make sure that the kickstart you are using creates a /boot/efi partition by including this:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">part</span> <span class="o">/</span><span class="n">boot</span><span class="o">/</span><span class="n">efi</span> <span class="o">--</span><span class="n">fstype</span><span class="o">=</span><span class="s2">&quot;efi&quot;</span> <span class="o">--</span><span class="n">size</span><span class="o">=</span><span class="mi">500</span>
</pre></div>
</div>
<p>Or use <code class="docutils literal notranslate"><span class="pre">reqpart</span></code> in the kickstart and Anaconda will create the required partitions.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>The --virt-uefi method is currently only supported on the x86_64 architecture.</p>

<h2>Debugging problems<a class="headerlink" href="#debugging-problems" title="Permalink to this headline"></a></h2>
<p>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.</p>
<p>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.:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="o">%</span><span class="n">pre</span>
<span class="n">chvt</span>
<span class="n">exec</span> <span class="o">&lt;</span> <span class="o">/</span><span class="n">dev</span><span class="o">/</span><span class="n">tty3</span> <span class="o">&gt;</span> <span class="o">/</span><span class="n">dev</span><span class="o">/</span><span class="n">tty3</span> <span class="mi">2</span><span class="o">&gt;/</span><span class="n">dev</span><span class="o">/</span><span class="n">tty3</span>
<span class="c1">#do stuff</span>
<span class="n">echo</span> <span class="n">hello</span> <span class="n">world</span>
<span class="o">%</span><span class="n">end</span>
</pre></div>
</div>
<p>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.</p>
<p>If lmc didn't handle the cleanup for some reason you can do this:
1. <code class="docutils literal notranslate"><span class="pre">sudo</span> <span class="pre">umount</span> <span class="pre">/tmp/lmc-XXXX</span></code> to unmount the iso from its mountpoint.
2. <code class="docutils literal notranslate"><span class="pre">sudo</span> <span class="pre">rm</span> <span class="pre">-rf</span> <span class="pre">/tmp/lmc-XXXX</span></code>
3. <code class="docutils literal notranslate"><span class="pre">sudo</span> <span class="pre">rm</span> <span class="pre">/var/tmp/lmc-disk-XXXXX</span></code> to remove the disk image.</p>
<p>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.</p>
<p>The logs from the qemu run are stored in virt-install.log, logs from
livemedia-creator are in livemedia.log and program.log</p>
<p>You can add <code class="docutils literal notranslate"><span class="pre">--image-only</span></code> to skip the .iso creation and examine the resulting
disk image. Or you can pass <code class="docutils literal notranslate"><span class="pre">--keep-image</span></code> to keep it around after the iso has
been created.</p>
<p>Cleaning up aborted <code class="docutils literal notranslate"><span class="pre">--no-virt</span></code> installs can sometimes be accomplished by
running the <code class="docutils literal notranslate"><span class="pre">anaconda-cleanup</span></code> 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 <code class="docutils literal notranslate"><span class="pre">anaconda-cleanup</span></code>.</p>
