When we designed the various "id" members, we ended up with:

    - system-id, which is the host-uuid from XAPI on XenServer.

    - iface-id, which defaults to xs-vif-uuid on XenServer but the
      administrator can override via XAPI with
      other-config:nicira-iface-id.

    - bridge-id, which defaults to xs-network-uuids on XenServer but
      the administrator can override via XAPI with nicira-bridge-id. 

    - xs-vif-uuid on XenServer.

This changes the latter to:

    - vif-uuid, which is xs-vif-uuid on XenServer.

So, for symmetry, should we:

    1. Use "vif-id" as the name (instead of "vif-uuid").

    2. Add a way to override the vif-(uu)id on XenServer via XAPI with
       other-config:nicira-vif-id?

Thanks,

Ben.
