For &lsquo;Smol machines&rsquo; (<code>smolvm</code>), achieving sub-second cold starts and seamless cross-platform execution isn&rsquo;t magic; it&rsquo;s a testament to leveraging powerful, battle-tested virtualization primitives provided by modern operating systems.</p> <p>This chapter dives into the bedrock of <code>smolvm</code>&rsquo;s architecture: the foundational virtualization concepts and the specific host-level technologies—<strong>Kernel-based Virtual Machine (KVM)</strong> on Linux and <strong>Apple&rsquo;s Hypervisor Framework</strong> on macOS—that make its innovative features possible. Understanding these underlying mechanisms is crucial for appreciating how <code>smolvm</code> can deliver lightweight, stateful, and instantly available virtual environments. We&rsquo;ll explore what these technologies are, how they work, and why they are essential building blocks for <code>smolvm</code>.</p>
