This is a big one, I’ll try to include the essential information needed.

OpenStack Instance Creation Problem

Setup

• Fresh OpenStack Yoga deployed using Kolla-Ansible on 4 servers Proxmox cluster
• OVS
• OPNsense VM for routing and firewall
• Two main networks (both through OPNsense):
  • vlan-interne (10.0.1.0/24): Internal OpenStack network (ens18 on the servers)
  • vlan-externe (10.1.1.0/24): External OpenStack network (ens19 on the servers, without ip)
• Multinode: 3 Controller, 4 Compute, 3 Network, 3 Storage, and 1 Monitoring nodes

Problem

Unable to create instances in OpenStack. Error message:

“Error waiting for instance to become ready: unexpected state ‘ERROR’, wanted target ‘ACTIVE'”

Nova Compute Logs

The Nova compute logs show the following error:

nova.exception.PortBindingFailed: Binding failed for port 59ab1ad8-4352-4d58-88b4-f8fb3d741f0d, please check neutron logs for more information.

Current Status

• The error suggests a port binding failure during instance creation.
• Neutron logs do not show any errors at all.
• All the services and containers are running without issue

Troubleshooting Steps Taken

1. Verified network and Kolla-Ansible configuration
2. Checked Nova compute logs
3. Reviewed OPNsense firewall rules
4. Completely redployed OpenStack from 0

Any insights or suggestions on resolving this port binding issue would be greatly appreciated.
