Title:
  missing ssh_host keys in /etc/ssh/

Status in cloud-init:
  Expired

Bug description:
  I'm using cloud-init 0.7.5-0ubuntu1.7 on ubuntu 14.04 as a glance
  image in an OpenStack deployment. I randomly saw failure to ssh to VM
  booted with this image. When I checked the VM from console, I find all
  ssh_host keys are missing from /etc/ssh/

  I do see logs of ssh-keygen runs in cloud-init.log, cloud-init-
  output.log and boot.log.

  And I don't see any failure of ssh key generation in the logs.
