Hi Enrico,

We (Linaro's Project Stratos
https://linaro.atlassian.net/wiki/spaces/STR/overview)
are interested in this stuff. 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.
