it needs to be defined on the nova api server config and the nova compute config
due to how the numa afinity policies work. at least i think that is the reason.
stephen dug into this while trying to fix https://bugs.launchpad.net/nova/+bug/1805891
https://review.openstack.org/#/c/624444/2

its documented in the docs i linked in my previous reply 

https://docs.openstack.org/nova/latest/admin/pci-passthrough.html#configure-nova-api-controller
and https://docs.openstack.org/nova/latest/admin/pci-passthrough.html#configure-pci-devices-compute
stephen has another patch up to make it even more explicit https://review.openstack.org/#/c/624445/


the conductor should not need the alias defiend.
