[PATCH v3 8/9] spapr: PEF: block migration |
Date: |
Fri, 19 Jun 2020 12:06:01 +1000 |
We haven't yet implemented the fairly involved handshaking that will be
needed to migrate PEF protected guests. For now, just use a migration
blocker so we get a meaningful error if someone attempts this (this is the
same approach used by AMD SEV).
