[libvirt] [PATCH 0/7] x86: Multi-key Total Memory Encryption (Intel)
This patch series provides support for launching an encrypted guest using Intel's Multi-key Total Memory Encryption (MKTME) feature. The purpose of this review is to get initial feedback and to get on par with libvirt development process. Considering we have not added tests, this is a preliminary patch and based on the community feedback, we expect more updates to follow. Total Memory Encryption (TME) provides the capability to encrypt the entirety of the physical memory of a system. MKTME builds on TME and adds support for multiple encryption keys. High Level flow: 1. Management tool calls virConnectGetDomainCapabilities which calls virNodeGetMKTMEInfo. This returns an XML document that includes the following: <feature> ... <mktme supported='yes'> <keys_supported> </keys_supported> </mktme> </feature> 2. If MKTME is supported management tool requests to start a guest calling virCreateXML(). The xml would include: <launchSecurity type='mktme'> <id>m0</id> <key_type>user</key_type> <key>samplekey</key> <encryption_algorithm>aes-xts-128</encryption_algorithm> </launchSecurity> 3. Libvirt makes system call with the provided information to generate a key handle using linux keyring services. Qemu uses the key handle to launch the workload. 4. Libvirt generate the QEMU cli arg to enable the MKTME feature, a typical args looks like this: # Qemu ...\ -machine pc,memory-encryption=m0 -object mktme-guest,id=m0,handle=${serial} Intel MKTME spec: https://software.intel.com/sites/default/files/managed/a5/16/Multi-Key-Total... TODO: Add tests for launch security of type mktme. WIP: Qemu and KVM patch to support Intel MKTME are in the process of upstreaming.
