Or do I need another patch on top? Hey sorry missed this comment.... It does seem to work for me, I've mostly tested pseries but I did test others too (that's how I saw the arm getchar limit). How are you observing it not waiting for migration? I put some sleeps in the migration script before echo'ing to the console input and it seems to be doing the right thing. Admittedly the test contains no way to programaticaly verify the machine was migrated the expected number of times, it would be nice to try to match that up somehow. Thanks, Nick
