Open Stack

Hello Lokendra:

Did you check the version of the ovn-controller service in the compute
nodes and the ovn services in the controller nodes? The services should be
in sync.

What is the "openstack network agent list" output? Do you see the OVN
controller, OVN gateways and OVN metadata entries corresponding to the
compute and controller nodes you have? And did you check the sanity of your
OVN SB database? What is the list of "Chassis" and "Chassis_Private"
registers? Each "Chassis_Private" register must have a "Chassis" register
associated.

Regards.
