The Solaris approach seems to be fully hierarchical as far as I can work out.
That seems to argue for extending the capabilities XML to describe nodes, in as much as the XML can start off as a flat list of NUMA nodes (for IBM) but later be made hierarchical if necessary.
Yes that is correct. We should not change the default - let the OS appply whatever policy it sees fit by default, since over time OS are tending towards being able to automagically determine & apply NUMA policy.
Or add another domain creation call which allows passing an additional set of hints. One of the hints would be initial cpu pinning.
