> Justin, then it's not a userspace vswitch, right? Correct, Open vSwitch requires a datapath (kernel module) to forward traffic, and a userspace daemon to configure the kernel module. There are userspace only implementations of the datapath, but they are only used for testing and are not supported in general.
