Bhyve supports SLIRP networking using the following syntax:
-s 12:0,e1000,slirp,mac=<macaddr>,open
Where "e1000" is a NIC model, "slirp" is the SLIRP backend and "open"
specifies open mode where external network is available to the guest.
The "open" mode is a recent addition in FreeBSD -CURRENT.
Unfortunately, bhyve does not provide a way to probe whether
the open mode is supported, so users will have to make sure
it's supported on their own.
For the reference, without the "open" mode, the guest will have no
outside network connectivity. To make this mode useful,
it is possible to configure forwarding from the host to the guest,
but it is not covered by this patch.
