Struct LaunchMeasurementV2 

pub struct LaunchMeasurementV2 {
    pub vmsa: Vec<u8>,
    pub value: Vec<u8>,
}

Generation 2 launch measurement: pre-VMSA digest and raw VMSA bytes stored separately so the vCPU count can change without invalidating the signed system version.

Fields

vmsa: Vec<u8>

Raw oak_sev_guest::vmsa::Vmsa bytes shared by all vCPUs.

value: Vec<u8>

SHA-384 digest of all measured pages except VMSA pages.

Implementations

impl LaunchMeasurementV2

pub fn try_resolve( &self, vcpus: usize, ) -> Result<[u8; 48], LaunchMeasurementError>

Resolves the full 48-byte launch measurement by applying the VMSA page update once per vCPU.

Errors

Returns an error if the measurement is not 48 bytes or the VMSA is larger than 4096 bytes.
