Hello everyone,

The openstack-ansible deployment was all good. Turns out it was a network configuration problem for the external network. Aside from the below issues which have been addressed, everything runs as expected now.

-OVN deployments fail when the provider bridge is defined for gateway hosts and not for compute nodes.
-Add split(',') python list to supported_provider_types on templates/horizon_local_settings.py.j2

Thank you everyone for all the help. This cleared out a lot of doubts.

Best regards.

Thanks, Roger. Super helpful.

If you’re attempting to launch the VM on that network it will fail, since that network is only plumbed to the net nodes as an 'external' network. For the VM, you will want to create a non-provider (tenant) network, which would likely be geneve, and then create a neutron router that connects to the external network and the tenant network. Your VM traffic would then traverse that router from compute->net node and out over the geneve overlay.

Keep us posted.

Hello James,

I appreciate the prompt response. Please see the output for openstack network show <net> , pasted at https://paste.opendev.org/show/bIhYhu6fDWoMaIiyaRMJ/

Thanks you

Hi Roger,

That output looks as I would expect, thank you.

Can you please provide the output for ‘openstack network show’ for the network being attached to the VM?

Thanks,
James

Hello Satish,

I appreciate your feedback and any help will be greatly appreciated. Please find the requested outputs pasted here: https://paste.opendev.org/show/bHWvGMUYW35sU43zUxem/ 

I've included outputs for one compute and one network/gateway node.

As a recap, among other nodes, the environment includes:

-2x compute - 1x NIC ens1 with IPv4 (geneve) - no bridges
-2x network/gateway nodes - 2x NICs - ens1 with IPv4 (geneve), ens2 as external net interface, br-vlan connected to ens2 bridge.

Let me know if you need further information. Much appreciated.

Thank you.
