Secure Encrypted Virtualization (SEV) is a feature found on AMD processors.
SEV is an extension to the AMD-V architecture which supports running encrypted
virtual machine (VMs) under the control of KVM. Encrypted VMs have their pages
virtual machines (VMs) under the control of KVM. Encrypted VMs have their pages
(code and data) secured such that only the guest itself has access to the
unencrypted version. Each encrypted VM is associated with a unique encryption
key; if its data is accessed to a different entity using a different key the
key; if its data is accessed by a different entity using a different key the
encrypted guests data will be incorrectly decrypted, leading to unintelligible
data.
The key management of this feature is handled by separate processor known as
AMD secure processor (AMD-SP) which is present in AMD SOCs. Firmware running
inside the AMD-SP provide commands to support common VM lifecycle. This
Key management for this feature is handled by a separate processor known as the
AMD secure processor (AMD-SP), which is present in AMD SOCs. Firmware running
inside the AMD-SP provides commands to support a common VM lifecycle. This
includes commands for launching, snapshotting, migrating and debugging the
encrypted guest. Those SEV command can be issued via KVM_MEMORY_ENCRYPT_OP
encrypted guest. These SEV commands can be issued via KVM_MEMORY_ENCRYPT_OP
ioctls.
Secure Encrypted Virtualization - Encrypted State (SEV-ES) builds on the SEV
support to additionally protect the guest register state. In order to allow a
hypervisor to perform functions on behalf of a guest, there is architectural
support for notifying a guest's operating system when certain types of VMEXITs
are about to occur. This allows the guest to selectively share information with
the hypervisor to satisfy the requested function.
Launching
---------
Boot images (such as bios) must be encrypted before guest can be booted.
MEMORY_ENCRYPT_OP ioctl provides commands to encrypt the images :LAUNCH_START,
Boot images (such as bios) must be encrypted before a guest can be booted. The
MEMORY_ENCRYPT_OP ioctl provides commands to encrypt the images: LAUNCH_START,
LAUNCH_UPDATE_DATA, LAUNCH_MEASURE and LAUNCH_FINISH. These four commands
together generate a fresh memory encryption key for the VM, encrypt the boot
images and provide a measurement than can be used as an attestation of the
images and provide a measurement than can be used as an attestation of a
successful launch.
LAUNCH_START is called first to create a cryptographic launch context within
the firmware. To create this context, guest owner must provides guest policy,
its public Diffie-Hellman key (PDH) and session parameters. These inputs
should be treated as binary blob and must be passed as-is to the SEV firmware.
For a SEV-ES guest, the LAUNCH_UPDATE_VMSA command is also used to encrypt the
guest register state, or VM save area (VMSA), for all of the guest vCPUs.
The guest policy is passed as plaintext and hypervisor may able to read it

The guest policy is passed as plaintext. A hypervisor may choose to read it,
but should not modify it (any modification of the policy bits will result
in bad measurement). The guest policy is a 4-byte data structure containing
several flags that restricts what can be done on running SEV guest.

LAUNCH_UPDATE_VMSA encrypts all the vCPU VMSAs for a SEV-ES guest using the

memory contents and, for a SEV-ES guest, the VMSA contents, that can be sent
to the guest owner as an attestation that the memory and VMSAs were encrypted
correctly by the firmware. The guest owner may wait to provide the guest
confidential information until it can verify the attestation measurement.
Since the guest owner knows the initial contents of the guest at boot, the
attestation measurement can be verified by comparing it to what the guest owner
expects.

An SEV-ES guest has some restrictions as compared to a SEV guest. Because the
guest register state is encrypted and cannot be updated by the VMM/hypervisor,
a SEV-ES guest:
- Does not support SMM - SMM support requires updating the guest register
state.
- Does not support reboot - a system reset requires updating the guest register
state.
- Requires in-kernel irqchip - the burden is placed on the hypervisor to
manage booting APs.
Debugging
-----------
Since memory contents of SEV guest is encrypted hence hypervisor access to the
guest memory will get a cipher text. If guest policy allows debugging, then
hypervisor can use DEBUG_DECRYPT and DEBUG_ENCRYPT commands access the guest
memory region for debug purposes. This is not supported in QEMU yet.

ABI compatibility levels for CPU models
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The x86_64 architecture has a number of `ABI compatibility levels`_
defined. Traditionally most operating systems and toolchains would
only target the original baseline ABI. It is expected that in
future OS and toolchains are likely to target newer ABIs. The
table that follows illustrates which ABI compatibility levels
can be satisfied by the QEMU CPU models. Note that the table only
lists the long term stable CPU model versions (eg Haswell-v4).
In addition to whats listed, there are also many CPU model
aliases which resolve to a different CPU model version,
depending on the machine type is in use.
