SEV-SNP Host Setup
Host configurations for AMD SEV-SNP machines
Categories:
Platform Setup
The host BIOS and kernel must be capable of supporting AMD SEV-SNP and the host must be configured accordingly.
The SEV Firmware version must be at least version 1.55 in order to have at least version 3 of the Attestation Report. The latest SEV Firmware version is available on AMD’s SEV Developer Webpage. It can also be updated via a platform OEM BIOS update.
The host kernel must be equal to or later than upstream version 6.16.1.
To build just the upstream compatible host kernel, use the Confidential Containers fork of AMDESE AMDSEV. Individual components can be built by running the following command:
./build.sh kernel host --install
