What failures are you seeing? Those were just recently added, and if
they are failing for you, it's worth getting them fixed. But I'm not
seeing them fail on my end.

Since checkpoints are brand new, and also created always on a running
image, should they also gain an <inactiveDomain> entry?  And if we are
fast enough, would it be worth mandating that entry on a checkpoint
REDEFINE (even though we can't do it for a snapshot REDEFINE)?
