Towards Modular Specification and Verification of Concurrent Hypervisor-based Isolation

Explore the ongoing efforts to formally verify the concurrent NOVA microhypervisor in a modular and tractable approach. Learn about NOVA, a microhypervisor designed to reduce critical code base and provide basic services for virtualization, isolation, scheduling, and management of physical system resources. Discover how the speakers decompose specifications and proofs of NOVA's hypercalls using concurrent separation logic. Gain insights into the open challenges faced in this verification process. Delve into the potential of formal verification for improving the security and reliability of hypervisor-based systems.
