Hi Michal,

I'd say it would be good to revive the old blueprint about bhyve
support and push the patches. Also, probably freebsd_net itself
deserve a blueprint on its own. And I guess it could be tested
independently of bhyve driver because as you might now qemu driver is
also supported on FreeBSD.

As for the bhyve, I think it's ok to push it now and mark it WIP for
example. I'd think it's not a small piece of code and will take some
time to review anyway.

But I think it cannot be merged until libvirt supports all the required
features (otherwise it'd be troublesome to setup gate jobs for bhyve for
I think).

As for the modifications to libvirt, unfortunately, they'll not get it
into the upcoming 1.2.3 as the freeze started already.
