For our use case, I'm considering mimicking Openstack's implementation - [1] - and expose a knob that indicates what is the number of PCIe root ports to be used upon the domain definition.
I wonder how open would the community be to having a machine type alias that would provide a "better" default - in the sense that it would have more root port controllers.
The problem with this suggestion is that the definition of "better" varies depending on who you ask :) There is no one-size-fits-all solution. libvirt follows the "mechanism, not policy" principle: the mechanism is already available, as documented in the page you were quoting, and the policy is better implemented in your application. OpenStack is a good example to follow in this regard. -- Andrea Bolognani / Red Hat / Virtualization
