BitVisor is a tiny hypervisor initially designed for mediating I/O access from a single guest OS. Its implementation is mature enough to run Windows and Linux, and can be used as a generic platform for various research and development projects.
Luvalley is a lightweight type-1 VirtualMachine Monitor (VMM) with novel architecture, to enable any OS to host virtual machines as pure applications by utilizing hardware virtualization extensions such as Intel VT and AMD-V.
A hardware supported hypervisor originally built for malware analysis. Features: Linux VM introspection, minimal detectability, small (~150KB), simple, and well documented. Can be used for other purposes. Support for Intel-VT & Windows coming soon.
Project's goal is to investigate the possiblity of fully-dynamic programming in memory-constrained environment like microcontrollers using virtual machines and a language+virtualmachine for some architectures.
