Thanks Jay,
Does it require any admin rights to do a custom query on the Nova
database ? And if so do you know where to look for such a query ? Which
part of the nova code to include in the filter ?
I'm not talking about doing something via the public HTTP API... I'm
talking about making a direct database query for our cinder information
directly from your Nova scheduler filter class.

OK, so not a normal user, but instead a service user (service being
cinder itself).
If this is a custom filter, I'd just go ahead and have the Cinder filter
to a custom query on the Nova database instead of using the
os-hypervisors API extension. I know that sounds like it's just adding
technical debt to your solution, but honestly, the os-hypervisors API
extension uses some questionable "queries" to construct its output.
Specifically, it queries all the Service objects, and then outputs the
first compute node matching the service_id in the compute_nodes table.
If there's >1 compute node on the host, the behaviour is entirely
undefined in the API extension.
