I've missed your patch on the visualisation list - sorry, my bad. I'll
have a look at it tomorrow, stay tuned.

As to the changes in the standard, in order to have anything accepted,
you'll have to post it as "official" comments, which will involve
accepting licensing terms and other legal nuisances:

https://www.oasis-open.org/committees/comments/index.php?wg_abbrev=virtio

Note that Paul Mundt of Huawei is a member of the committee, so you may
try to rely his changes through him, if it's easier.

Either way, thanks for your feedback!
