TLDR
This paper motivates VCC, describes the verification methodology, the architecture of VCC is described, and the experience using VCC to verify the Microsoft Hyper-V hypervisor is reported on.Abstract:
VCC is an industrial-strength verification environment for low-level concurrent system code written in C. VCC takes a program (annotated with function contracts, state assertions, and type invariants) and attempts to prove the correctness of these annotations. It includes tools for monitoring proof attempts and constructing partial counterexample executions for failed proofs. This paper motivates VCC, describes our verification methodology, describes the architecture of VCC, and reports on our experience using VCC to verify the Microsoft Hyper-V hypervisor.read more

A Secure and Formally Verified Linux KVM Hypervisor
TL;DR: Microverification as discussed by the authors decomposes a commodity hypervisor into a small core and a set of untrusted services so that the entire hypervisor can be verified by verifying the core alone.

A Temporal Logic of Nested Calls and Returns
TL;DR: This work introduces a temporal logic of calls and returns (CaRet) for specification and algorithmic verification of correctness requirements of structured programs and presents a tableau construction that reduces the model checking problem to the emptiness problem for a Buchi pushdown system.

Amortised Memory Analysis Using the Depth of Data Structures
TL;DR: A related system for bounding the stack space requirements is described which uses the depth of data structures, by expressing potential in terms of maxima as well as sums, by adding extra structure to typing contexts to describe the form of the bounds.
