+Subject: [PATCH] vfio: Make migration support experimental
+
+Support for migration of vfio devices is still in flux.  Developers
+are attempting to add support for new devices and new architectures,
+but none are yet readily available for validation.  We have concerns
+whether we're transferring device resources at the right point in the
+migration, whether we're guaranteeing that updates during pre-copy are
+migrated, and whether we can provide bit-stream compatibility should
+any of this change.  Even the question of whether devices should
+participate in dirty page tracking during pre-copy seems contentious.
+In short, migration support has not had enough soak time and it feels
+premature to mark it as supported.
+
+Create an experimental option such that we can continue to develop.
+
+[Retaining previous acks/reviews for a previously identical code
+ change with different specifics in the commit log.]
