Open Stack

Hi Lokendra:

Please open a launchpad bug with all the system information, including the
chassis list. It could be useful to know why you are deploying DHCP agents
on a ML2/OVN deployment. If you upgraded/changed the chassis ID, please
report that too. If you are using ML2/OVN, you should also check what is
the status of the OVN agents (I don't see that in the agent list you
printed).

Regards.
