If this is targeting KVM specifically then I'd look also at other 
1. leave swap out - I understand this is done already
2. wipe out the SSH keys, the random seed, optionally touch 
/.autorelabel to force a selinux relabel upon next boot (this takes a 
time and cpu)
3. install tuned with virtual-guest profile
4. disable tso and gso on the virtual nic and wipe out 
5. run ntp & ntpdate
6. enable serial tty for `virsh console` access if needed

Most of the above I do in the following ks for cloudstack
