Thanks for the help Eugen,
This log is from the linuxbridge of the controller node. Compute nodes
are not logging errors.
Follows the output of the "openstack network agent list"

I'm using this OpenStack cloud to run my master's experiment. I turned
off all nodes, and after a few days I called again and from that the VMs
were not remotely accessible.
So I delete existing networks and re-create. It was in an attempt to
solve the problem.
Here is an attached image. Neutron is creating multiple interfaces on
the 10.0.0.0 network on the router.

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
Zitat von Marcio Prado <marciopr...@marcioprado.eti.br>:
Good afternoon,
For no apparent reason my Neutron stopped working.
I deleted the networks, subnets and routers, created everything again.
But it does not work. The logs are:
