Up 156.83 seconds This does not seem to be caused by ssh key generation (I tried to disable it, with no keytypes enabled there is still > 150 s delay), not does it seem to be related to the resizing operation. I suspect some other step requiring randomness to generate some kind of ID, but I don't know.
