| H A D | amd-memory-encryption.rst | 6 SEV is an extension to the AMD-V architecture which supports running encrypted
15 AMD secure processor (AMD-SP), which is present in AMD SOCs. Firmware running
16 inside the AMD-SP provides commands to support a common VM lifecycle. This
21 Secure Encrypted Virtualization - Encrypted State (SEV-ES) builds on the SEV
28 Launching (SEV and SEV-ES)
29 --------------------------
38 For a SEV-ES guest, the ``LAUNCH_UPDATE_VMSA`` command is also used to encrypt the
42 the firmware. To create this context, guest owner must provide a guest policy,
43 its public Diffie-Hellman key (PDH) and session parameters. These inputs
44 should be treated as a binary blob and must be passed as-is to the SEV firmware.

79 in any of QEMU's built-in CPU configuration. To expose SGX (and SGX Launch
80 Control) to a guest, you must either use ``-cpu host`` to pass-through the
81 host CPU model, or explicitly enable SGX when using a built-in CPU model,
