This turns out to be a known issue with resizing--resizes require a
second host to migrate the instance to, since both instances have to
exist for a period of time. So, if you're using a single dev box, like
I do, or if the simple scheduler picks the same host as the instance
you're trying to resize, you get this migration error.

(At least it says "Migration error" now; when I first saw this, the
error looked like an invalid entity...)
