Hi,
Yes, Michael is right. This error message is probably suspicious :) So, in ML2/OVS its neutron-ovs-agent who should create br-int during the start. It’s in [1]. So is neutron-openvswitch-agent running on Your node? Or maybe if You are using some other solution rather than ML2/OVS, maybe You should change to other than “openvswitch” interface driver in neutron-l3-agent’s config?

Hi Rony,
Based on this line:
BridgeDoesNotExist: Bridge br-int does not exist
...it looks as if your SDN-provider-of-choice (OVS ?) may need some attention. As a wild stab in the dark, is the bridge defined in bridge_mappings, for the default bridge, present, and available to be patched (hypothetically via OVS, or another provider) to br-int ?
Cheers, Michael.
