Abstract
Systems and methods for encryption support for virtual machines. An example method may comprise initializing, by a firmware module associated with a virtual machine running on a host computer system, an exclusion range register associated with the virtual machine with a value specifying a first portion of guest memory. The first portion of the guest memory may include an exclusion range marked as reserved. The second portion of the guest memory may b e encrypted using an ephemeral encryption key. Virtual machine firmware may identify, in the second portion of the guest memory, an instruction to a virtual device associated with the virtual machine, copy data corresponding to the instruction to the first portion of guest memory, and alert the hypervisor of the data stored in the first portion of guest memory.
