Hi I have a different idea to get the migration tests faster. Namely, just stop letting enter the completation stage until we are ready to use it. I need that functionality also for vfio migration, so as I have to create the patches, can we put on hold the last two patches and give me a couple of days? Thomas, do you care if I get the whole sets of patches through the migration tree? Almost everything is migration related, and I am changing the same files that Daniel, so it is easier if I can get them into my tree. Later, Juan.
