In this talk, we will demonstrate that SEV VMs can be reliably single-stepped. To lay the foundation for further microarchitectural attack research against SEV, we introduce the reusable SEV-Step framework. Besides reliable single-stepping, SEV-Step provides easy access to common attack primitives like page fault tracking and cache attacks against SEV. All features can be used interactively from user space.
