From 6ba996bb458f4620e62984f2561c270a636bb500 Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Wed, 16 Dec 2015 11:47:35 +0000 Subject: Postcopy: Send events/change state on incoming side I missed the calls to send migration events on the destination side as we enter postcopy. Take care when adding them not to do it after state has been freed.
