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 +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 +includes commands for launching, snapshotting, migrating and debugging the +encrypted guest. Those SEV command can be issued via KVM_MEMORY_ENCRYPT_OP +ioctls. + +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, +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 +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. + +The guest policy is passed as plaintext and hypervisor may able 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. +See KM Spec section 3 and 6.2 for more details. + +The guest policy can be provided via the 'policy' property (see below) + +# ${QEMU} \ + sev-guest,id=sev0,policy=0x1...\ + +Guest owners provided DH certificate and session parameters will be used to +establish a cryptographic session with the guest owner to negotiate keys used +for the attestation. + +The DH certificate and session blob can be provided via 'dh-cert-file' and +'session-file' property (see below + +# ${QEMU} \ + sev-guest,id=sev0,dh-cert-file=<file1>,session-file=<file2> + +LAUNCH_UPDATE_DATA encrypts the memory region using the cryptographic context +created via LAUNCH_START command. If required, this command can be called +multiple times to encrypt different memory regions. The command also calculates +the measurement of the memory contents as it encrypts. + +LAUNCH_MEASURE command can be used to retrieve the measurement of encrypted +memory. This measurement is a signature of the memory contents that can be +sent to the guest owner as an attestation that the memory was 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. + +LAUNCH_FINISH command finalizes the guest launch and destroy's the cryptographic +context. + +See SEV KM API Spec [1] 'Launching a guest' usage flow (Appendix A) for the +complete flow chart. + +To launch a SEV guest + +# ${QEMU} \ + -machine ...,memory-encryption=sev0 \ + -object sev-guest,id=sev0,cbitpos=47,reduced-phys-bits=1 + +Debugging +----------- +Since memory contents of SEV guest is encrypted hence hypervisor access to the +guest memory will get a cipher text.
