<h2 id="safekit-kvm-tco">SafeKit for KVM: 2-Node SANless KVM Cluster</h2>
<p><strong>SafeKit for KVM</strong> delivers seamless <strong>High Availability</strong> while significantly reducing TCO (Total Cost of Ownership). By eliminating the hardware and operational overhead of traditional clustering, SafeKit offers a lean, 2-node HA alternative to complex virtualization stacks.</p>
<ul>
<li><strong>Zero SAN Investment for HA:</strong> Achieve full redundancy using shared-nothing architecture. It works with standard local disks, removing the need for expensive SAN hardware, fiber channel switches, and specialized storage maintenance usually required for High Availability.</li>
<li><strong>Hardware-Agnostic Redundancy:</strong> Avoid vendor lock-in. Build your High Availability cluster using any server brand or internal storage type, extending the lifecycle of existing hardware and lowering replacement costs.</li>
<li><strong>Simplified HA Operations:</strong> No specialized &ldquo;clustering expert&rdquo; is required to maintain uptime. SafeKit’s plug-and-play modules and unified web console reduce the man-hours needed for HA deployment and daily monitoring.</li>
<li><strong>Cost-Predictable Licensing:</strong> Unlike subscription-heavy models, SafeKit provides High Availability via a one-time perpetual license. This ensures predictable budgeting and eliminates the risk of annual price hikes for critical infrastructure.</li>
<li><strong>True 2-Node HA Efficiency:</strong> Most High Availability solutions require a third &ldquo;witness&rdquo; node to prevent split-brain. SafeKit delivers a robust 2-node cluster, saving 33% on hardware, power, and rack space from day one.</li>
</ul>
<p>By consolidating <strong>High Availability</strong> into a lightweight software layer, SafeKit delivers enterprise-grade redundancy and business continuity at a fraction of the cost of traditional virtualization suites.</p>

<h2 id="safekit-kvm-ha-cluster">How the SafeKit software simply implements a KVM high availability cluster without shared storage on a SAN?</h2>
<h3 id="what-is-the-safekit-ha-solution-for-kvm">What is the SafeKit HA solution for KVM?</h3>
<p>SafeKit brings high availability to KVM between two servers of any brand.</p>
<p>This article explains how to implement quickly a KVM cluster without shared storage on a SAN and without specific skills.</p>
<p>The principle of the solution is to put the critical application in a virtual machine under KVM. SafeKit implements <strong>real-time replication and automatic failover of the virtual machine</strong>.</p>
<p>Note that KVM is the free hypervisor included in all Linux versions.</p>
<h3 id="how-can-i-run-multiple-applications-in-a-high-availability-kvm-cluster-without-a-san">How can I run multiple applications in a high-availability KVM cluster without a SAN?</h3>
<p>Several applications can be put in <strong>several virtual machines replicated and restarted by SafeKit</strong>. You have the possibility to migrate each virtual machine between both servers with the SafeKit console and thus balance the load in an <strong>active-active cluster</strong>.</p>
<h3 id="should-i-choose-high-availability-at-the-application-level-or-the-virtual-machine-vm-level">Should I choose high availability at the application level or the virtual machine (VM) level?</h3>
<p>With SafeKit, you have the flexibility to choose the redundancy model that fits your needs.</p>
<p><strong>VM-level redundancy</strong> (for KVM or Hyper-V) is the simplest to implement as it replicates the entire virtual machine, requiring no knowledge of the internal application.</p>
<p>Alternatively, <strong>application-level redundancy</strong> is more granular; it only replicates specific data folders and restarts the application services rather than the entire OS.</p>
<p>While VM-level HA is easier to set up, application-level HA is hypervisor-agnostic and can run across physical, virtual, or cloud environments.</p>
<h3 id="what-are-the-distinctive-advantages-of-safekit-for-kvm-high-availability-compared-to-competitors">What are the distinctive advantages of SafeKit for KVM high availability compared to competitors?</h3>
<p>SafeKit differentiates itself from traditional KVM clustering solutions through its <strong>shared-nothing architecture</strong> and simplified management. While most competitors require complex distributed file systems (like Ceph) or a central SAN to manage VM failover, SafeKit provides:</p>
<ul>
<li><strong>Integrated Real-Time Replication:</strong> Data synchronization is built directly into the solution, ensuring that KVM virtual machines are mirrored synchronously without the overhead of managing a separate storage layer.</li>
<li><strong>Simplified 2-Node Clustering:</strong> Unlike enterprise stacks that recommend a 3-node &ldquo;witness&rdquo; quorum, SafeKit delivers full high availability with just two redundant servers. <a href="/best-practises/heartbeat-failover-quorum-windows-linux-cluster/">Learn more about our heartbeat and quorum mechanism</a>.</li>
<li><strong>Unified Management:</strong> Administrators can manage VM failover, replication, and load balancing through a single SafeKit console , making it accessible to teams without specialized clustering expertise.</li>
<li><strong>Custom Checkers:</strong> SafeKit goes beyond hardware monitoring; it utilizes <strong>custom checkers</strong> to detect if a VM has crashed, automatically triggering a local restart or a failover to the redundant node. The system is also highly extensible, allowing for the easy integration of new, user-defined custom checkers tailored to your specific environment.</li>
</ul>
<h3 id="how-does-safekit-reduce-the-tco-total-cost-of-ownership-compared-to-vmware-type-solutions">How does SafeKit reduce the TCO (Total Cost of Ownership) compared to VMware-type solutions?</h3>
<p>Unlike most high-availability solutions on the market, SafeKit is designed to operate with the <strong>absolute minimum hardware overhead</strong> , without compromising security or reliability. Key savings compared to VMware or complex open-source alternatives include:</p>
<ul>
<li><strong>True 2-Node Efficiency:</strong> While most enterprise stacks or open-source solutions require a 3-node &ldquo;witness&rdquo; quorum to prevent split-brain, SafeKit delivers full high availability with just <strong>two redundant servers</strong>.</li>
<li><strong>Zero Storage Costs:</strong> SafeKit uses a shared-nothing architecture that works with local disks, removing the need for expensive SAN or vSAN hardware and specialized storage networking.</li>
<li><strong>No Forced Subscriptions:</strong> Unlike modern subscription-only models, SafeKit offers a <strong>perpetual license</strong>. You own your software, avoiding the &ldquo;subscription trap&rdquo; and unpredictable annual price hikes.</li>
<li><strong>Low Operational Expense (OPEX):</strong> As a plug-and-play solution, it requires no specialized training or expensive external consultancy for maintenance, unlike complex open-source clustering tools.</li>
<li><strong>CPU-Independent Pricing:</strong> Licensing is independent of the number of CPUs or cores. With just two licenses for two nodes, you can protect multiple KVM virtual machines.</li>
</ul>
<h3 id="is-it-possible-to-set-up-a-kvm-cluster-without-san-or-complex-clustering-skills">Is it possible to set up a KVM cluster without SAN or complex clustering skills?</h3>
<p>Yes. This article explains how to <a href="/quick-install/safekit-quick-installation-guide-with-kvm/"><strong>quickly implement a KVM cluster</strong></a> without the need for specialized SAN management or complex HA clustering skills. By using SafeKit’s <strong>automated failover scripts</strong> to handle the replication and restart of <strong>KVM</strong> virtual machines, you get a robust redundancy solution that is significantly simpler to deploy and maintain than traditional enterprise virtualization stacks.</p>
<h3 id="beyond-kvm-which-applications-and-environments-can-safekit-protect">Beyond KVM, which applications and environments can SafeKit protect?</h3>
<p>SafeKit is a versatile high-availability solution that extends far beyond standard virtual machine failover. It enables <strong>synchronous real-time replication</strong> and automatic failover for a wide range of critical workloads, including:</p>
<ul>
<li><strong>Virtual &amp; Physical Environments:</strong> Complete Hyper-V or KVM virtual machines.</li>
<li><strong>Container Orchestration:</strong> Docker, Podman, and K3s (Kubernetes) environments.</li>
<li><strong>Data &amp; Services:</strong> Individual file directories, services, and various databases.</li>
<li><strong>Cloud Infrastructure:</strong> High availability for Cloud applications.</li>
</ul>
<p>SafeKit also provides <strong>Farm Clusters</strong> with native <strong>Network Load Balancing and Failover</strong> for stateless applications like <strong>Web Servers</strong>.</p>

<h2 id="safekit-kvm-ha-how-it-works">How the SafeKit KVM cluster works?</h2>
<p>The following steps are described for one KVM virtual machine inside one mirror module. Each replicated virtual machine runs in an independent mirror module (with a maximum of 32 virtual machines) with a primary server that can be either the KVM server 1 or the KVM server 2.</p>
<h3 id="1-how-does-real-time-replication-work-for-kvm">1. How does real-time replication work for KVM?</h3>
<p>Server 1 (PRIM) runs the KVM VM (virtual machine). SafeKit replicates in real time the VM files (virtual hard disk, VM configuration). Only changes made in the files are replicated across the network.</p>
<img src="/wp-content/uploads/2023/02/safekit-prim-second-300.png" width="300" alt="File replication at byte level in a mirror KVM cluster">
<p>The replication is <a href="/best-practises/synchronous-replication-vs-asynchronous-replication/">synchronous</a> with no data loss on failure contrary to asynchronous replication.</p>
<p>You just have to configure the VM directory name in SafeKit. There are no pre-requisites on disk organization. The directory may be located in the system disk.</p>
<h3 id="2-what-happens-during-an-automatic-kvm-failover">2. What happens during an automatic KVM failover?</h3>
<p>When Server 1 fails, Server 2 takes over. SafeKit restarts the KVM VM on Server 2. KVM finds the files replicated by SafeKit uptodate on Server 2.<br>
The VM continues to run on Server 2 by locally modifying its files that are no longer replicated to Server 1.</p>
<img src="/wp-content/uploads/2023/02/safekit-stop-alone-300.png" width="300" alt="Failover of KVM in a mirror cluster">
<p>The failover time is equal to the fault-detection time (set to 30 seconds by default) plus the VM reboot time.</p>
<h3 id="3-how-is-data-synchronized-after-a-kvm-failure">3. How is data synchronized after a KVM failure?</h3>
<p>Failback involves restarting Server 1 after fixing the problem that caused it to fail. SafeKit automatically resynchronizes the VM files.</p>
<img src="/wp-content/uploads/2023/02/safekit-resynchro-alone-300.png" width="300" alt="Failback in a mirror KVM cluster">
<p>Failback takes place without disturbing the KVM VM, which can continue running on Server 2.</p>
<h3 id="4-how-is-normal-kvm-operation-restored">4. How is normal KVM operation restored?</h3>
<p>After reintegration, the VM files are once again in mirror mode, as in step 1. The system is back in high-availability mode, with the KVM VM running on Server 2 and SafeKit replicating file updates to Server 1.</p>
<img src="/wp-content/uploads/2023/02/safekit-second-prim-300.png" width="300" alt="Return to normal operation in a mirror KVM cluster">
<p>If the administrator wishes the VM to run on Server 1, this can be done manually through the web console at an appropriate time, or automatically through configuration.</p>
<h3 id="safekit-mirror-cluster-configure">How to configure a SafeKit KVM Cluster?</h3>
<img src="/wp-content/uploads/2024/03/21-module-kvm-edit-config-1.png" width="694" alt="SafeKit Web Console: 2-node KVM cluster dashboard for VM replication and automatic failover.">
<p>The <strong>SafeKit web console</strong> provides an intuitive interface to configure high availability of your critical applications. In just a few steps, you can configure a <strong>SafeKit KVM cluster</strong> to ensure business continuity:</p>
<ul>
<li>Put in <code>VM_PATH</code>, the root path of the replicated directory (/var/lib/libvirt/images) where the KVM VM files reside.</li>
<li>Enter in <code>VM_NAME</code>, the name of the KVM virtual machine (VM1).</li>
</ul>
<p>The SafeKit cluster includes a dedicated <a href="/best-practises/heartbeat-failover-quorum-windows-linux-cluster/" title="Technical details on heartbeat and split-brain prevention">split-brain checker to resolve network isolation issues</a> without the need for a third witness machine or an additional heartbeat network.</p>
<h3 id="safekit-mirror-cluster-monitoring">How to monitor a SafeKit KVM cluster?</h3>
<img src="/wp-content/uploads/2024/03/14-monitoring-prim-second.png" width="604" alt="SafeKit Web Console: Real-time monitoring of a 2-node mirror KVM cluster showing PRIM and SECOND states with active data replication.">
<p>The <strong>SafeKit management console</strong> offers a unified view of your high availability infrastructure. It allows administrators to monitor the <strong>operational state</strong> of the cluster and track data synchronization in real-time.</p>
<p>For a 2-node KVM cluster, the console clearly displays the roles of each server:</p>
<ul>
<li><strong>PRIM (Primary):</strong> The active node currently running the application and managing the Virtual IP. It performs writes to the local storage and real-time replication to the secondary node.</li>
<li><strong>SECOND (Secondary):</strong> The standby node receiving synchronous byte-level updates. It is ready to take over instantly if the Primary fails.</li>
<li><strong>ALONE State:</strong> Visually alerts you when the cluster is running on a single node (e.g., during maintenance or after a failure), indicating that redundancy is temporarily lost.</li>
<li><strong>Resynchronization Progress:</strong> When a failed node recovers, its status turns orange during background data reintegration, ensuring no downtime during the &ldquo;return to normal&rdquo; phase.</li>
</ul>
<p>Beyond simple status icons, the interface provides <strong>one-click failover orchestration</strong> , allowing you to manually reassign the primary role for planned maintenance while ensuring continuous availability for user activity.</p>
<p>Note that if you deploy several VMs for replication and failover, you will have multiple PRIM/SECOND widgets. This allows independent failover for each VM and the ability to distribute the load across servers.</p>
