Nope. In my case this does not help. I just get Booting a command list and hang. I've tried removing console=ttyS0 before and did it again now just for a test. The hang happens not only with cloud images, but with VMbuilder images and install ISOs too. What bothers me, actually, is that I can't find similar cases, reported by other people.
