Open Stack

Hi Developers,

Let me explain my point of view on this topic and please share your thoughts
in order to merge this new feature ASAP.

My understanding is that multi-host is nova-network HA  and we are
implementing this bp
https://blueprints.launchpad.net/neutron/+spec/quantum-multihost for the
same reason.
So, If in neutron configuration admin enables multi-host:
etc/dhcp_agent.ini

# Support multi host networks
# enable_multihost = False

Why do tenants needs to be aware of this? They should just create networks
in the way they normally do and not by adding the "multihost" extension.
I could be totally wrong and crazy, so please provide some feedback.

Thanks,

Edgar

Subject:  Re: About multihost patch review

Hi,
Edgar Magana has commented to say:
'This is the part that for me is confusing and I will need some
clarification from the community. Do we expect to have the multi-host
feature as an extension or something that will natural work as long as the
deployment include more than one Network Node. In my opinion, Neutron
deployments with more than one Network Node by default should call DHCP
agents in all those nodes without the need to use an extension. If the
community has decided to do this by extensions, then I am fine' at

I have commented back, what is your opinion about it?
