Delve into the Secure VM Service Module (SVSM), its role in providing secure services like secure boot, and its importance in enabling live migration of guest images. Learn about the VMPL architecture, necessary Linux kernel and KVM support, and ongoing efforts to create an open-source SVSM for Linux. Gain insights into guest security, integrity protection, boot flow, virtual TPM, and the development of Linux SVSN. Presented by Thomas Lendacky from AMD at a Linux Foundation event, this talk covers key aspects of confidential guest services and secure virtualization.
