That additional separation is useful for some workloads.<\/p>\n<h2>Kernel requirements<\/h2>\n<p>A KVM guest runs its own kernel, making it appropriate for custom kernel configurations and workloads that cannot operate under the host&#8217;s shared kernel.<\/p>\n<h2>Isolation boundaries<\/h2>\n<p>VMs offer a stronger isolation boundary in many threat models, although security still depends on hypervisor patching, device configuration, and operational controls.<\/p>\n<h2>Windows and non-Linux guests<\/h2>\n<p>Windows and non-Linux operating systems generally require full virtualization rather than LXC&#8217;s Linux-kernel sharing model.<\/p>\n<h2>Operational tradeoffs<\/h2>\n<p>LXC often uses fewer virtualization resources for Linux services. KVM offers flexibility at some overhead cost. Decide based on guest requirements, isolation, tooling, and measured performance.<\/p>\n<h2>Final thoughts<\/h2>\n<p>Start with the simplest architecture that meets your requirements, document the configuration, and test changes before applying them to production.
