Boot and run the bastion hosts from customized LiveCD or LiveDVD on real DVD-ROM read-only drives with no persistent storage (updating the LiveCD/DVD image periodically with updates and with additional authentication users/data as needed; DVD+RW works very well for this as long as the boot drive is a DVD-ROM and not an RW drive!);
How about using Stateless CentOS system with:
http://plone.lucidsolutions.co.nz/linux/io/using-centos-5.2-stateless-linux-support-on-a-flash-based-root-filesystem#section-13,
then mounting KVM guests system as read-only, shutting it down and then
setting KVM guests virtual drive file as read-only for KVM. That ways
change of read-only to write would have no effect on the HDD/image.
But I do not know if this is possible from KVM "read-only" point of view.
