I believe it should be possible to plumb up arbitrary vm to vm network

vms in different vimage jails, and using netgraph as a linkage medium,
but I haven't tried them.
Is there any current support for vde2 aside from using
vde2_plug2tap? (Does that even work? I believe vde2 likes to open
the tap interface exclusively. I need to bring up a bhyve test
environment to check fully.)
How exactly does the bhyve network stack work through bridging? I'm
imaging it's tying in to bridging APIs?
I'm assuming bhyve-to-bhyve network communication is also possible?
I can't imagine it'd be too hard to implement vde2 support for
networking...it'd give me more control over my VMs and give easier
integration with SIMH VMs.
OpenVSwitch I know less about...but I'm aware it is another virtual
switch and it works on FreeBSD...not sure if it has a kernel module
or if it's in userspace. With vde2 I know for sure it can be
attached to a tap interface and therefore a bridge.
A virtual switch for bhyve would be a useful feature if there aren't
any plans for one. Get up there and have it in base. ;)
Unrelated: any plans for a special bhyve-to-bhyve communication
bus? Not too useful of a feature...I can't think of any use for it
off-hand aside from dedicating a VM to administrating VMs without
exposing much to the host beyond configurations.
