When attaching a volume, if CONF.cinder.cross_az_attach=False, we attempt to lookup the AZ that the instance is in and compare that to the volume AZ. The instance AZ lookup involves getting host aggregates which are in the API database, and in superconductor mode the cell conductor can't access to the API database. For volume attach, we could remove this check from the compute service since we already check this in nova-api so the check in nova-compute is redundant. However, we still have a problem with checking this during boot from volume where nova-compute creates the volume and then attaches it. At that point it's too late and we'll fail. We should eventually create volumes during boot from volume in conductor, like we've talked about doing with neutron ports during server create, but that's not something we have today so we need to point out this limitation.
