From: Ashish Kalra <ashish.kalra@amd.com> Introduce a new AMD Memory Encryption GUID which is currently used for defining a new UEFI environment variable which indicates UEFI/OVMF support for the SEV live migration feature. This variable is setup when UEFI/OVMF detects host/hypervisor support for SEV live migration and later this variable is read by the kernel using EFI runtime services to verify if OVMF supports the live migration feature.
