Nova-compute relies on qemu (which itself relies on KSM) which is affected by a nasty kernel bug in the stock Trusty kernel on fresh installs. As a safety measure, it is probably worthwhile to insert a check that causses a puppet error() if the running kernel is one of the affected one since any VM running on such a host would be broken and can cause outages.
