    Bringing High Availability to Quantum Server

    Introduction Quantum is going to be a core project in OpenStack next release (Folsom). If we use Quantum as the Network Manager, we can’t configure nova-network in multi_host mode, that’s why we loose High Availability for nova-network. Quantum-Server can be a single-point-of-failure, that’s why I was thinking about how to fix that.

    Openstack Essex – Guide for Ubuntu 12.04
