Agreed it is dangerous to restart neutron-ovs-cleanup. It's meant to run
once at system startup to cleanup ovs interfaces.
I like suggestion b) or at least something along those lines. Will have
to look into that some more to ensure it's a possibility.

Title:
neutron-ovs-cleanup can have unintended side effects
Status in neutron package in Ubuntu:
Triaged
Bug description:
neutron-ovs-cleanup is dangerous (i.e. breaks networking of random
instances) to run at random times but this is not at all obvious from
looking at the file. This is a problem because operators tend to
assume restarting ${service}* is safe (at least from unintended side
effects), but that's not the case with 'neutron*'.
Please:
a) add some obvious and visible documentation to the file that
neutron-ovs-cleanup should only be restarted after
openvswitch-switch has been and what might happen if it isn't.
and/or
b) add some sort of sanity check that the openvswitch-switch process'
start time is recent and becoming a noisy no-op if it's not.
and/or
c) consider renaming the init script(s) to something that doesn't
match 'neutron*'
