Workspace changes remain visible on the host.</p> <p>PVM (Pagetable-based Virtual Machine) lets us run these microVMs inside an x86_64 Linux VM without exposed VMX/SVM or nested virtualization. It still provides the <code>/dev/kvm</code> interface used by SBX.</p> <p>First, install and boot the PVM host kernel from <a href="https://rfcorner.in/posts/porting-pvm-to-linux-7.2/">Porting PVM to Linux 7.2</a>, including its <code>pti=off</code> boot setting. You also need an SBX-compatible PVM guest kernel, saved as <code>vmlinux</code> below.</p>
