Hi Hanna,
The next step is getting agreement on how the vhost-user device state
interface will work. Do you want to draft the new vhost-user protocol
messages and put together slides for discussion with Michael, Jason,
Juan, and David in the next KVM call? That might be the best way to
get agreement. Doing it via email is possible too but I guess it will
take longer.

If you don't want to design the vhost-user protocol changes yourself
then someone on this email thread can help with that.
