Discussion on Live Migration of AMD SEV encrypted VMs.

Discussions on Guest APIs, specifically if the APIs can cover both
AMD SEV and Intel TDX platforms and exploring common interfaces
which can be re-used for both the above platforms, for example,
exploring a common hypercall API interface, with reference
to the posted KVM patch-set.

SEV Live Migration Acceleration uses an alternative migration
approach relying on a Migration Helper (MH) running in guest
context. The fast migration for encrypted virtual
machines typically use a Migration Handler that lives in OVMF.
As part of this microconference, we can have additional
discussions on the design and development of the MH, especially,
the suggested approach to use KVM/Qemu Mirror VM concept to
run the MH in a Mirror VM/vCPU which runs in parallel to the
primary encrypted VM in the same Qemu process context.
