In this scenario Host Configuration is used -to specify the physical host type and other configurations for the host -system. This information is populated by the Cloud Operator is in OVSDB in -Open_vSwitch configuration data in the external_ids field as a key value pair. -This information is then read by ODL and made available to networking-odl -through REST API. Networking-odl populates this information in agent_db in -Neutron and is then used by Neutron scheduler. This information is required -for features like Port binding and Router scheduling. - -Refer to this link for detailed design for this feature. - -https://docs.google.com/presentation/d/1kq0elysCDEmIWs3omTi5RoXTSBbrewn11Je2d26cI4M/edit?pref=2&pli=1#slide=id.g108988d1e3_0_6 - -Related ODL changes: - -https://git.opendaylight.org/gerrit/#/c/36767/ - -https://git.opendaylight.org/gerrit/#/c/40143/ - -Host Configuration fields -------------------------- - -- host-id - -This represents host identification string. This string will be stored in -external_ids field with the key as odl_os_hostconfig_hostid. -Refer to Neutron config definition for host field for details on this field. - -http://docs.openstack.org/kilo/config-reference/content/section_neutron.conf.html - -- host-type - -The field is for type of the node. This value corresponds to agent_type in -agent_db. Example value are “ODL L2” and “ODL L3” for Compute and Network node -respectively. Same host can be configured to have multiple configurations and -can therefore can have both L2, L3 and other configurations at the same time. -This string will be populated by ODL based on the configurations available -on the host. See example in section below. - -- config - -This is the configuration data for the host type. Since same node can be -configured to store multiple configurations different external_ids key value -pair are used to store these configuration. The external_ids with keys as -odl_os_hostconfig_config_odl_XXXXXXXX store different configurations. -8 characters after the suffix odl_os_hostconfig_config_odl are host type. -ODL extracts these characters and store that as the host-type fields. For -example odl_os_hostconfig_config_odl_l2, odl_os_hostconfig_config_odl_l3 keys -are used to provide L2 and L3 configurations respectively. ODL will extract -"ODL L2" and "ODL L3" as host-type field from these keys and populate -host-type field. - -Config is a Json string.
