KVM: Arm Confidential Compute Architecture Support

Explore the Arm Confidential Compute Architecture (CCA) support in KVM through this 30-minute conference talk from KVM Forum. Delve into the reference software architecture built on Arm v9-A's Realm Management Extension, enabling Confidential Virtual Machines execution. Learn how Realm VMs prevent access by privileged software like hypervisors while allowing VM management. Discover the current status and future plans for KVM's Arm CCA support, and gain insights into the changes needed to run Linux as a Realm. Understand how this technology enhances security by protecting code, register state, and data used by VMs from unauthorized access.
