OVS seems great but it doesn't seem to garner much hype these days. Does it carry too much connotations from OpenStack, or why isn't it the defacto solution for all L2 bridging/virtual networking for containers/VMs/routers/etc?

Most people just need data to come out the NICs on certain tags. If you need L2 between guests (in a way you can't just do that from the network in the first place) you can either just do it in container or on the host without having to set up an entire virtual switch. The configuration manages fine outside an OpenStack environment it's just a ton of work for very little squeeze.
