[RFC v2 10/18] guest memory protection: Add guest memory protection interface

2020-05-20 Thread David Gibson
Several architectures have mechanisms which are designed to protect guest memory from interference or eavesdropping by a compromised hypervisor. AMD SEV does this with in-chip memory encryption and Intel has a similar mechanism. POWER's Protected Execution Framework (PEF) accomplishes a similar g
