By introducing a connection tracking feature in Open vSwitch, thanks to the latest Linux kernel, we greatly simplified the maze of virtual network interfaces on OpenStack compute nodes and improved its networking performance. This feature will appear soon in Red Hat OpenStack Platform.

Any non-trivial firewalling requires you keep track of the connections to and from the machine. This is called “stateful firewalling”. Indeed, even such basic rule as “don’t allow machines from the Internet to connect to the machine while allowing the machine itself to connect to servers on the Internet” requires stateful firewall. This applies also to virtual machines. And obviously, any serious cloud platform needs such protection.
