Brian,
Thanks so far - I seem to have forgotten to say that this is all on
CentOS 7.
My nova.conf and neutron.conf files both appear to be configured
correctly. I'm fairly certain that the problem lies in the ovs
configuration, but I don't know where. What other information do you need?
Regards,
Dan

I need more information in order to figure out where the network connection dropped on your systems. From your information it is hard to figure out what went wrong. Are you using CentOS or RHEL and which version?
