I use NAT (with virtio), as I have always done. According to the virt-
manager config widget, "macvtap does not work for host->guest
communication".

The Fedora guest is F28 Server. When I reported the problem yesterday
it hadn't been updated in months. I updated it last night but it still
isn't working (see my reply to Kai Bojens <kb@xxxxxxxxxx> in this
thread).
