I use an alias to select when to, and not to, use host keys;

alias ssht='ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no'

ssht floaty.vm # does not use host key checking

ssh my.bastion.host # validates host key

Really I ought to get SSHFP records populated when my vm's are created...
