XMHF is an eXtensible and Modular Hypervisor Framework that strives to be a comprehensible and flexible platform for performing hypervisor research and development. The framework allows others to build custom (security-sensitive) hypervisor-based solutions (called "hypapps").

XMHF is designed to achieve three goals – modular extensibility, automated verification, and high performance. XMHF includes a core that provides functionality common to many hypervisor-based security architectures and supports extensions that augment the core with additional security or functional properties while preserving the fundamental hypervisor security property of memory integrity (i.e., ensuring that the hypervisor’s memory is not modified by software running at a lower privilege level).

XMHF advocates a "rich" single-guest execution model where the hypervisor framework supports only a single-guest and allows the guest direct access to all performance-critical system devices and device interrupts.

XMHF currently runs on recent multicore x86 hardware virtualized platforms with support for dynamic root of trust and nested (2-dimensional) paging. The framework is capable of running unmodified legacy multiprocessor capable OSes such as Windows and Linux.
