Given these interfaces are probably slower than physical ones, is RX / TX from a single core a possibility? Distributor? What are people doing to get it to work? Is it better to use some other kind of interface like a fake virtual Intel NIC, where the RSS might be supported, instead? Thanks, Matthew.
