Hyper-V's Virtual Secure Mode in KVM - Project Update

Explore the progress of implementing Hyper-V's Virtual Secure Mode (VSM) in KVM in this conference talk from the Linux Plumbers Conference. Delve into the challenges of supporting Windows Credential Guard, a security feature enabled by default in Windows 11 that utilizes VSM hypervisor enlightenments. Learn about the proof of concept implementation and upstreaming plan presented at the KVM forum 2023. Gain insights into the project's current status, including plans for publishing the first patch series. Discuss contentious topics and explore how VSM introduces concepts that may overlap with other KVM discussions, such as multiple execution contexts per-vCPU and dynamic permission updates of IOMMU and MMU page tables.
