--- Comment #1 from Mark Johnston <markj@FreeBSD.org> ---
I think this was perhaps fixed by commit 9da9560c4dd35.
In particular, I can't reproduce the problem on main:
root@freebsd:~ # devctl detach vtnet0
Oct 30 15:51:13 freebsd dhclient[322]: receive_packet failed on vtnet0: Device
not configured
Oct 30 15:51:13 freebsd dhclient[322]: ioctl(SIOCGIFFLAGS) on vtnet0: Operation
not permitted
Oct 30 15:51:13 freebsd dhclient[322]: Interface vtnet0 no longer appears
valid.
Oct 30 15:51:13 freebsd dhclient[322]: No live interfaces to poll on - exiting.
Oct 30 15:51:13 freebsd dhclient[322]: exiting.
Oct 30 15:51:13 freebsd dhclient[322]: connection closed
Oct 30 15:51:13 freebsd dhclient[322]: exiting.
vtnet0: detached
root@freebsd:~ # devctl detach virtio_pci2
virtio_pci2: detached
