I was trying to look at the last status of all this. Few questions for you: - Was the spec ever posted to virtio-dev list ? I thought that's the very first step before we merge the code. - Any follow up on this patchset ? Thanks. I will be happy to help otherwise and have cycles to work on this if you need my help. -- viresh
