Thanks. I applied patches 1-5, 10 and 11 to the block branch, i.e. leaving out the transfer rate stuff. I believe this is fairly independent so it makes sense to apply the rest of the series without it, but if you think I should dequeue all of the patches, let me know. The main reason for not applying 6-9 is that I think migration is broken, but I'll wait for Juan and/or Paolo to confirm. If a respin is required, you can also fix the three default machine types.
