Open vSwitch (OVS) is one of the more popular ways to provide VM connectivity in OpenStack. Rackspace has been using Open vSwitch in production since late 2011. In this session, we will detail the challenges faced with managing and upgrading Open vSwitch across a large heterogenous fleet. Finally, we will share some of the tools we have created to monitor OVS availability and performance.
Specific topics covered will include:
Why upgrade OVS?
Minimizing downtime with upgrades
Bridge fail modes
Kernel module gotchas
