OK, I deinstall the old port, took your port, built it, and installed it.

When I started libvirtd, I got this:

Trying to start bhyve did not work.

After some investigation, I did the following:

service local_unbound stop


Then I started libvirtd again:

At this point, I could see the virbr0 device:

virbr0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        ether 02:b8:18:5f:0f:00
        inet 192.168.122.1 netmask 0xffffff00 broadcast 192.168.122.255
        nd6 options=1<PERFORMNUD>
        id 00:00:00:00:00:00 priority 32768 hellotime 2 fwddelay 4
        maxage 20 holdcnt 6 proto rstp maxaddr 2000 timeout 1200
        root id 00:00:00:00:00:00 priority 32768 ifcost 0 port 0


I was then able to do:

virsh -c 'bhyve:///system'
    start bhyve

and start a VM.
This is good progress!

Once thing I observed is that if I killed the libvirtd process,
it did not clean up the dnsmasq process that it started:

/usr/local/sbin/dnsmasq
--conf-file=/usr/local/var/lib/libvirt/dnsmasq/default.conf

and a subsequent restart of libvirtd would fail.


The devel/libvirt port is looking a lot better with your changes.
Can you push these changes into the port?

I filed bugs 190767 and 190783, but did not get any response
from the port maintainer, jgh at .
