| |
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.
Peter Gonda (2): KVM: SEV: Update svm_vm_copy_asid_from for SEV-ES KVM: SEV: Allow launch vmsa from mirror VM
