When that happens, restoring from a backup is your best friend.</p> <p>Here&rsquo;s how I restored my broken KVM VM disk image using weekly backups stored on a NAS share.</p> <h2 id="the-situation"> The situation <a class="anchor" href="#the-situation">#</a> </h2> <p>I have a VM called <code>runner.home.arpa</code> running on KVM, and its disk got corrupted. The VM disk images live at <code>/var/lib/libvirt/images/</code>, and my backups are stored on a NAS mounted at <code>/mnt/backups/runner.home.arpa/</code>.</p> Automated KVM VM Provisioning with Ansible and OSBuild on RHEL9 https://blog.nousiainen.xyz/docs/automated-vm-provisioning-with-ansible-and-osbuild/ Thu, 03 Jul 2025 14:00:00 +0300 https://blog.nousiainen.xyz/docs/automated-vm-provisioning-with-ansible-and-osbuild/ <h1 id="automated-kvm-vm-provisioning-with-ansible-and-osbuild-on-rhel9"> Automated KVM VM Provisioning with Ansible and OSBuild on RHEL9 <a class="anchor" href="#automated-kvm-vm-provisioning-with-ansible-and-osbuild-on-rhel9">#</a> </h1> <h2 id="introduction"> Introduction <a class="anchor" href="#introduction">#</a> </h2> <p>When I started looking into automating my homelab VM provisioning, I was surprised by the lack of examples combining Ansible with OSBuild for KVM environments. Not many tutorials focus on KVM, so I wanted something that used Red Hat&rsquo;s tooling - as I run a RHEL homelab.</p> <p>I used to provision my homelab virtual machines by hand and eventually I got tired of doing it since I like to tinker around a lot and constantly add new VMs. So, I decided to automate the process using the combination of Ansible and OSBuild.</p>
