Some of this dependency on the hypervisor is unavoidable but will keep
improving as the architecture allows it. OTOH, Zone-Wide primary storage
should be easy to add to the simulator, I'll look into that.

The original problem posed by David about the NPE comes because of a
config check from the `hypervisor_capabilities` table, if you include
a row for the simulator similar to the other hypervisors then you
should be able to get past the NPE.
