Date: 2016-10-25

CERN has been running a production OpenStack Cloud for several years. It was based on Nova Network from the start, with a few changes on the upstream code to adapt to the specifics of our internal networking infrastructure. With more than 6000 hypervisors split in tens of cells, 20000 virtual machines and an heterogeneous setup (KVM and HyperV) moving to Neutron with minimal disruption to users posed a significant challenge. In this talk we'll describe the Neutron plugin we wrote to integrate wi
