Although somewhat different from the virtualization part of the subject, both... - AMD (Secure Memory Encryption, and Memory Guard) on both EPYC and Ryzen Pro today and - Intel (Multi Key Total Memory Encryption) likely on Xeon in the near future ... also do seem to have some OS dependant bits that would be needing configuration and awareness. You can search them both. This is one of Intel's papers on its version of memory encryption... https://software.intel.com/sites/default/files/managed/a5/16/Multi-Key-Total-Memory-Encryption-Spec.pdf
