Hi, We are building a multi-node physical set-up of OpenStack Newton. The goal is to finally integrate the set-up with OVN. Lab details: 1 Controller, 2 computes
CentOS-7.3, OpenStack Newton, separate network for mgmt and tunnel OVS version: 2.6.1 I followed the following guide to deploy OpenStack Newton using the PackStack utility: http://networkop.co.uk/blog/2016/11/27/ovn-part1/ Before I started integrating with OVN, I made sure that the set-up(ML2 and OVS) was working by launching VMs. VMs on cross compute node were able to ping each other. Now, I followed the official guide for OVN integration: http://docs.openstack.org/developer/networking-ovn/install.html Error details : Neutron Server log shows : ERROR networking_ovn.ovsdb.impl_idl_ovn [-] OVS database connection to OVN_Northbound failed with error: '{u'error': u'unknown database', u'details': u'get_schema request specifies unknown database OVN_Northbound', u'syntax': u'["OVN_Northbound"]'}'. Verify that the OVS and OVN services are available and that the 'ovn_nb_connection' and 'ovn_sb_connection' configuration options are correct. The issue is ovsdb-server on the controller binds with the port 6641.instead of 6640. # netstat -putna | grep 6641 tcp 0 0 192.168.10.10:6641 0.0.0.0:* LISTEN 809/ovsdb-server # netstat -putna | grep 6640 (shows no output) Now, OVN NB DB tries to listen on port 6641, but since it is used by the ovsdb-server, it's unable to. PID of ovsdb-server is 809, while the pid of OVN NB DB is 4217. OVN NB DB logs shows this: 2017-05-23T12:58:09.444Z|01421|ovsdb_jsonrpc_server|ERR|ptcp:6641:0.0.0.0: listen failed: Address already in use 2017-05-23T12:58:11.946Z|01422|socket_util|ERR|6641:0.0.0.0: bind: Address already in use 2017-05-23T12:58:14.448Z|01423|socket_util|ERR|6641:0.0.0.0: bind: Address already in use Solutions I tried: 1) Completely fresh installing everything. 2) Tried with OVS 2.6.0 and 2.7, same issue on all. 3) Checked and verified : SB and NB configuration options in plugin.ini are exactly correct. Please help. Let me know. if additional details are required.
