(since 2.2) How does this work with libvirt's current insistence that it manually resumes the guest on the destination in order to give feedback to the source on whether it was successful? I'm not sure if enabling this bool is the right thing to do, or if we just need more visibility (such as events rather than the current state of polling) for libvirt to know that it is time to resume the destination and start the post-copy phase. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
