I would like to setup quantum in folsom to provide a functionality similar to the nova-network multihost feature. Where can I read about this ?

The equivalent of Nova's multi-host networking mode has not been implemented in Quantum. I'm hoping that it will be implemented in the Havana release.

This was recently discussed on the openstack-dev list:

I recommend reading this newly released Mirantis blog that covers this topic: www.mirantis.com/blog/a-new-agent-management-approach-in-quantum-for-openstack-grizzly/

Unfortunately that post is a bit misleading IMO. The quantum-scheduler blueprint marked implemented in grizzly originally included multi-host l3 and dhcp in grizzly, but that part was not actually implemented. More here: http://lists.openstack.org/pipermail/openstack-dev/2013-March/006571.html

Russel, as the new PTL for Nova, I think your answer should be considered authoritative. I'm pretty disappointed though that this blueprint was not implemented in Grizzly as the way Quantum is designed today it breaks https://wiki.openstack.org/wiki/BasicDesignTenets.

Hmm, it seems that you and Roman Prykhodchenko from Mirantis have different info, check his answer: http://www.mirantis.com/blog/a-new-agent-management-approach-in-quantum-for-openstack-grizzly/ (www.mirantis.com/blog/a-new-agent-management-approach-in-quantum-for-openstack-grizzly/)

That's the official guide, so I guess is the best source!

Cheers!

I'm sorry, I missed the fact that there is no much information there about multihost support. If I'm not wrong, that feature is under deployment. Here you can see some details about that https://blueprints.launchpad.net/quantum/+spec/quantum-multihost.

You can also look at the High Availability guide to learn about making the Quantum Server highly available.

That's not the same as multi-host, but it does help make Quantum more reliable.

Something like this I think will be relevant when it lands: Change > 24771 I can't link because of missing Karma!
