Operating System : Ubuntu 18.04.1 LTS

1 x controller and 1 x compute

Openstack installation : Rocky

Guide following:https://docs.openstack.org/install-guide/ (https://docs.openstack.org/install-gu...)

Each node has 2 NICs:-

NIC 1 (eth0) - https://imgur.com/a/7QbcU1E (gateway: 192.168.0.1)

NIC 2 (eth1) (Has internet connection) - https://imgur.com/a/tyddrjA (gateway: 192.168.10.1)

Too many log files, too little time.

Have you found any error messages in your logs?

what does "ip netns" return? Do you see qrouters or only qdhcp entries?
