Hi,
is there anything in the linuxbridge-agent logs on control and/or
compute node(s)?
Which neutron services don't start? Can you paste "openstack network
agent list" output?
The important question is: what was the cause of "neutron stopped
working" and why did you delete the existing networks? It probably
would be helpful knowing the reaseon to be able to prevent such
problemes in the future. Or are the provided logs from before?
We experience network/neutron troubles from time to time, and
sometimes the only way to fix it is a reboot.
Regards,
Eugen
