SEV is an extension to the AMD-V architecture which supports running multiple VMs under the control of a hypervisor. The SEV feature allows the memory contents of a virtual machine (VM) to be transparently encrypted with a key unique to the guest VM. The memory controller contains a high performance encryption engine which can be programmed with multiple keys for use by a different VMs in the system. The programming and management of these keys is handled by the AMD Secure Processor firmware which exposes a commands for these tasks. The KVM SEV patch series introduced a new ioctl (KVM_MEMORY_ENCRYPTION_OP) which is used by qemu to issue the SEV commands to assist performing common hypervisor activities such as a launching, running, snapshooting, migration and debugging guests. The following links provide additional details: AMD Memory Encryption whitepaper: http://amd-dev.wpengine.netdna-cdn.com/wordpress/media/2013/12/AMD_Memory_Encryption_Whitepaper_v7-Public.pdf AMD64 Architecture Programmer's Manual: http://support.amd.com/TechDocs/24593.pdf SME is section 7.10 SEV is section 15.34 Secure Encrypted Virutualization Key Management: http://support.amd.com/TechDocs/55766_SEV-KM API_Specification.pdf KVM Forum slides: http://www.linux-kvm.org/images/7/74/02x08A-Thomas_Lendacky-AMDs_Virtualizatoin_Memory_Encryption_Technology.pdf Video of the KVM Forum Talk: https://www.youtube.com/watch?v=RcvQ1xN55Ew --- The complete patch series is available : https://github.com/codomania/qemu/tree/v8 Using these patches we have succesfully booted and tested a guest both with and without SEV enabled. TODO: * Add SEV guest migration support * Add SEV guest snapshot and restore support Changes since v8: - move sev.c from accel/kvm to target/i386 - update query-sev-launch-measure to return error when measurement is not available - update flatview_read to use slow path when attrs.debug=1 is set - fix the buffer overflow - use '-' when adding new member in SevInfo QMP structure Changes since v6: - add support to specify cbitpos in sev-guest object - add 'info sev' HMP command - add 'query-sev' and 'query-launch-measure' QMP commands - rework the logic to query the memory encryption mask when walking guest pagetable for debug Changes since v5: - drop MEMTXTATTRS_DEBUG macro, caller now specify attrs.debug=1 when needed. - drop DPRINTF and use trace points to output the debug messages Changes since v4: - extend sev-guest object to add new properties 'dh-cert-file', 'session-file' etc. - emit SEV_MEASUREMENT event when measurement is available - add migration blocker - add memory encryption cpuid support - rebase the series with recent qemu tree Changes since v3: - update to newer SEV spec (0.12 -> 0.14) - update to newer KVM RFC and use KVM_MEMORY_ENCRYPTION_OP ioctl instead of KVM_ISSUE_SEV. - add support to encrypt plfash Changes since v2: - rename ram_ops to ram_debug_ops - use '-' rather than '_' when adding new member in KvmInfo struct - update sev object to use link properties when referencing other objects - use ldq_phys_debug in tlb_info_64 and mem_info_64. - remove sev-guest-policy object, we will revisit it after basic SEV guest support is merged. - remove kernel API from doc and add SEV guest LAUNCH model. The doc will be updated as we integerate the remaining SEV APIs. Changes since v1: - Added Documentation - Added security-policy object. - Drop sev config parsing support and create new objects to get/set SEV specific parameters - Added sev-guest-info object. - Added sev-launch-info object. - Added kvm_memory_encrytion_* APIs. The idea behind this was to allow adding a non SEV memory encrytion object without modifying interfaces. - Drop patch to load OS image at fixed location. - updated LAUNCH_FINISH command structure. Now the structure contains just 'measurement' field. Other fields are not used and will also be removed from newer SEV firmware API spec.
