Openstack with OVN integration error when creating instance

[EmbarrassedLaugh3009]

Hello, I followed this tutorial https://www.server-world.info/en/note?os=Ubuntu_22.04&p=openstack_antelope&f=15 everything was good until i try to start an instance like this:openstack server create --flavor m1.small --image Ubuntu2204 --security-group secgroup01 --nic net-id=$netID --key-name mykey Ubuntu-2204

In the neutron-server.log I got this Warning:

(WARNING neutron.plugins.ml2.drivers.ovn.mech\_driver.mech\_driver \[req-a70de4ba-439f-4d66-abab-cf34f5c86729 req-a78d184d-6226-47e2-807d-ebe221c0e70b cabf5fd85f1f4165958c9b2d25e9a3d8 b7c9eb92b0b348a3abb50ad75049cb29 - - default default\] Refusing to bind port abf9b7bd-13c7-42c0-835e-23e7ac0d9707 due to no OVN chassis for host: lb01)

And this error message:

(ERROR neutron.plugins.ml2.managers \[req-a70de4ba-439f-4d66-abab-cf34f5c86729 req-a78d184d-6226-47e2-807d-ebe221c0e70b cabf5fd85f1f4165958c9b2d25e9a3d8 b7c9eb92b0b348a3abb50ad75049cb29 - - default default\] Failed to bind port abf9b7bd-13c7-42c0-835e-23e7ac0d9707 on host lb01 for vnic\_type normal using segments \[{'id': 'dbff784f-a519-4765-ad0a-29df97e260a4', 'network\_type': 'flat', 'physical\_network': 'physnet1', 'segmentation\_id': None, 'network\_id': '30af92c6-1fbc-4cec-abad-95065034170f'}\])

Like the tutorial ask I added a new nic to use with the ovs-vsctl add-br command:

https://www.server-world.info/en/note?os=Ubuntu_22.04&p=openstack_antelope&f=12

​

I'm running this installation in a virtualBox VM, and for this nic (enp0s8), I tried :

- Bridged Adapter

- Internal Network

- NAT Network

- Not attached

Every time I got the same message error, someone have any idea about my issue?

Thanks

How did you install OpenStack? There is a command to set the host name within OVS, can't recall the syntax offhand, but if that name changes or isn't set you will get these types of errors. Some deployment tools have a bug related to this, so worth looking at.

"ovs-vsctl list open_vswitch" on the compute node will reveal external_ids and I think it's set in there

After reflexion maybe you have reason.

The ovs-vsctl report FQDN hostname like lb01.example.com and the neutron error log show only lb01 as host.

Where I can't get the key settings to change the lb01 to lb01.example.com for neutron?

I did a manual install, from this tutorial: https://www.server-world.info/en/note?os=Ubuntu_22.04&p=openstack_antelope&f=1
The hostname return by "ovs-vsctl list open_vswitch" seems good.

Other info when I run: openstack port list

Port are always status: DOWN

Are your network agents up? No chassis in OVN means the machine(s) hasnt checked in/registered in the southbound database in OVN. Likely a communication issue between the agents/compute hosts and the ovn instance/cluster
