systemd name network interfaces when Fedora is run on top of different
hypervisors? If xen or kvm is used how does systemd name network
interfaces?

> Systemd will name the device based on the bus/device/function of the
interfaces, so there could be some differences in the name chosen
depending on the hypervisor used (since each hypervisor may chose a
difference bus/dev/function for a given emulated interface.
It's important to note that the Fedora Cloud image, we disable this
feature (ln -s /dev/null /etc/udev/rules.d/80-net-name-slot.rules),
because systemd's priority is consistency of naming when there are
multiple interfaces on the same system. By and large, our concern is with
consistency of a *single* device name whereever the image boots, so the
network interface is traditional eth0 (or eth* if more than one).
