While I have nothing to offer on the bug, DragonFly BSD 3.4 doesn't
have guest drivers for virtio-net; you may want to use e1000 as your
paravirtualized NIC. (re: virtio-net -- I worked on Tim Bisson's port
of FreeBSD's vtnet driver, but when I last worked on it, it was slower
in both TCP_STREAM and TCP_RR than e1000, when connected to TAP; so
there was work left to do...)
