Subject: [PATCH 0/2] KVM: SEV: Allow for mirroring of SEV-ES VMs
Date: Tue, 21 Sep 2021 08:03:43 -0700 [thread overview]
Message-ID: <20210921150345.2221634-1-pgonda@google.com> (raw)
To mirror SEV-ES VMs the mirror VM needs to call LAUNCH_UPDATE_VMSA
before the original VM runs LAUNCH_FINISH. This allows the mirror's
vCPUs to be encrypted into the SEV-ES guests context and measured into
the launch digest.
