We already read it to get the value of the ovn-bridge-mappings configuration. The OpenStack plugin needs to know which Chassis has connectivity to a given network name. There will probably be more ... there is an unresolved issue where our OpenStack plugin needs to know whether a given Chassis is using the DPDK or Linux datapath so it can tell the compute part of OpenStack (nova) what virtual interface type to use for VMs on that host. I've tried to find other ways to resolve this, but it seems the simplest solution overall is to expose a bit more data in external_ids of Chassis. -- Russell Bryant _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
