lguest is a small hypervisor designed to run Linux under Linux for 32-bit x86 machines. Rusty Russell wrote it as a proof of concept hypervisor in Linux to demonstrate the paravirt ops (it was previously called lhype). Because it is small, it is easy to understand and contribute to. Performance is improving with development.
