<h1>Clear Linux Guest Virt Manager</h1>
<p>date: 2019-03-11T01:39:09-07:00</p>
<h2 id="introduction"><strong>Introduction</strong></h2>
<ul>
<li>download, convert, and resize the provided kvm-legacy image</li>
<li>create a virtual machine and launch it from <code>virt-manager</code></li>
</ul>
<p>But it’s not immediately clear from the instructions if you can use <code>virt-manager</code>,
because they recommend their script which runs <code>qemu-system-x86_64</code> directly.
Which is fine, but maybe you find it easier to customize the options using the <code>virt-manager</code> gui interface.</p>
<h2 id="how-to"><strong>How To</strong></h2>
<p>Assuming you have <code>libvirt</code> and <code>kvm</code> set up with <code>virt-manager</code>, you can:</p>
<ul>
<li>download the <a href="https://cdn.download.clearlinux.org/releases/current/clear/" target="_blank">clear-*-legacy-kvm.img.xz</a></li>
<li>verify the checksum</li>
<li>extract it <code>unxz clear-*-legacy-kvm.img.xz</code></li>
<li><code>mv clear-*-legacy-kvm.img.xz /var/lib/libvirt/images/</code></li>
<li>create a virtual machine in <code>virt-manager</code> using the image</li>
</ul>
<p>There is not an os template for Clear Linux, but <strong>Fedora29</strong> works fine for me.
As a bonus, <code>virsh console</code> is configured and ready to go.</p>
<h2 id="convert-raw-qcow2-and-resize"><strong>Convert Raw -&gt; Qcow2 and Resize</strong></h2>
<p>The image has a gpt partition table. I am not sure if that is the reason why,
but <code>fdisk</code> does not seem to work for resizing the partition. However, <code>parted</code> works fine.</p>
<p>The <a href="https://cdn.download.clearlinux.org/releases/current/clear/" target="_blank">image download</a> is an 8gb sparse raw image. You may wish to convert that to qcow2
and and resize before creating the virtual machine. Here is how to do that.</p>
<ol>
<li>convert the sparse raw image to qcow2
<div class="highlight"><pre><span></span><code><span class="go">qemu-img convert -f raw -O qcow2 clear*.img clear.qcow2</span>
</code></pre></div></li>
<li>resize the image to taste
<div class="highlight"><pre><span></span><code><span class="go">qemu-img resize clear.qcow2 20G</span>
</code></pre></div></li>
<li>create the virtual machine in <code>virt-manager</code> gui</li>
<li>boot the virtual machine: <code>virsh start clearvm</code></li>
<li>log in: <code>virsh console clearvm</code></li>
<li>install a bundle which contains <code>parted</code>
<div class="highlight"><pre><span></span><code><span class="go">swupd bundle-add clr-installer</span>
</code></pre></div></li>
<li>expand <code>/</code> partition and file system with <code>parted</code> and <code>resize2fs</code>
<div class="highlight"><pre><span></span><code><span class="go">parted /dev/vda resizepart</span>
<span class="gp">&gt;</span> Fix/Ignore? Fix
<span class="gp">&gt;</span> Partition number? <span class="m">1</span>
<span class="gp">&gt;</span> End? <span class="o">[</span>8590MB<span class="o">]</span>? <span class="m">100</span>%
<span class="gp">&gt;</span> size2fs /dev/vda1
</code></pre></div></li>
