[neutron][ovn] networking-ovn plugin support for multiple remote ovsdb-server


Hi All,

I have testing OpenStack (Queens Version) with OVN and works, but when I
want to cluster the ovsdb-server, OpenStack stuck to create neutron object.

based on my discussion in openvswitch mailing list (
https://mail.openvswitch.org/pipermail/ovs-discuss/2019-August/049175.html),
my ovsdb-server clustering databases are working. Is networking-ovn support
to connect to multiple ovsdb-server?

something like this in ml2_conf.ini
[ovn]
ovn_nb_connection = tcp:10.101.101.100:6641,tcp:10.101.101.101:6641,tcp:
10.101.101.102:6641
ovn_sb_connection = tcp:10.101.101.100:6642,tcp:10.101.101.101:6642,tcp:
10.101.101.102:6642

networking-ovn-metadata-agent.ini
[ovn]
ovn_sb_connection = tcp:10.101.101.100:6642,tcp:10.101.101.101:6642,tcp:
10.101.101.102:6642

Below is the full step to create ovsdb-server and neutron services.
- step 1: bootstrapping ovsdb-server cluster :
http://paste.openstack.org/show/766812/
- step 2: creating neutron service in controller :
http://paste.openstack.org/show/766464/
- step 3: creating neutron service in compute :
http://paste.openstack.org/show/766465/

But when I try to create neutron resource, Its always hang (only neutron
resource).

This is the full logs of all nodes, contain:
http://paste.openstack.org/show/766461/
- all openvswitch logs
- port (via netstat)
- step bootstraping ovsdb-server

Neutron logs in controller0: paste.openstack.org/show/766462/

Is networking-ovn support to connect to multiple ovsdb-server?
