PoC Usage This repo contains a VMM that boots an SEV-SNP guest with a custom kernel. The VMM and kernel are a stripped-down version of a project of mine. A modified Linux kernel is required to run on the host: https://github.com/Freax13/linux/tree/for-amd. The Proof of Concept can be run like thi...
