Alternative idea, inspired by "Thus, if you hit any bugs, you are on your own" (http://libvirt.org/formatdomain.html#elementsCPU wrt 'host-passthrough'): A config option to determine if we use host-model or host-passthrough. Y.
I do not think the engine should go to this level. ie- it can ask for passthrough as a feature, and the actual implementation is handled by vdsm.
If vdsm decides over host-passthrough or host-model, then how will the engine user know what exactly his VM gets. I think vdsm must be told exactly what to do.
