Hi Tobin,
as mentioned in the reply to the QEMU patches posted by Tobin, I think the
firmware helper approach is very good, but there are some disadvantages in the
idea of auxiliary vCPUs. These are especially true in the VMM, where it's much
nicer to have a separate VM that goes through a spec

This is a demonstration of fast migration for encrypted virtual machines
using a Migration Handler that lives in OVMF. This demo uses AMD SEV,
but the ideas may generalize to other confidential computing platforms.
With AMD SEV, guest memory is encrypted and the hypervisor cannot access
or move it.
