Are you doing any other first-boot initialization on the cloned VMs? Are
you (or could you) use cloud-init for this?
If so, you can run:
cloud-init clean [--seed] [--logs] [--machine-id]
before cloning - or inside the cloned image using guestfish etc. I'm not
sure if this actually removes the existing host keys, but if it doesn't,
you could manually rm them as well.
Then optionally you can provide cloud-init metadata when the clones boot
if you want to set different network parameters, or perform other
initialization like creating additional user accounts etc.
