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.

I had posted some spec quite some time ago, but it wasn't in the form
of patches against the .tex documentation files yet. It's been laying
aside for quite a while, since I've been busy w/ other things.

Will you be fine if I take that up and restart the thread ?

Yeah, we went past that and here is the last version I posted.

https://lists.oasis-open.org/archives/virtio-comment/202106/msg00033.html

which I took back later on to let Enrico do it, as he wanted to.

And here is the last version from Enrico:

https://lists.oasis-open.org/archives/virtio-comment/202106/msg00048.html

Lets see how this goes in coming days.
