2019 KVM Forum.
Introduced the process for LIVE MIGRATION of SEV.
Have to use SP to perform these tasks. But it is not so quick -> becomes a bottleneck.
SET UP a SEV MIGRATION HELPER.
Source Hypervisor uses a SEND API to migrate the MH.
Destination hypervisor uses RECEIVE API to receive the MH.
MH migrates the remainder of the guest
Uses CPU AES instruction, AMD SP not involved
Migration at multiple Gbps. (relatively quick.)
-> Prepare for SNP release.
