[Engine-devel] qemu machine type / datacenter machine version

[Andrew Cathrow]

It is only configured in the database today.
A good short term solution would be exposing this in the engine-config tool to save users having to hack the database, and potentially set this during setup.
But long term we need to incorporate the notion of per VM config versions, right now we take the config version from the cluster, which isn't the best approach. We need to merge the two concepts - host/cluster capabilities and VM config version.
