However, the name is abusrd: ens33.
Where is eth0?

By default systemd now names interfaces using firmware/BIOS provided
index numbers (e.g. eno1), but if that info is not available (possibly
because you're inside vmplayer) it falls back to naming after
firmware/BIOS provided PCI-E hotplug slot index numbers -- which is what
you're seeing here.

Why the change?

It's in order to ensure *predictable* NIC names across reboots.

How do I revert that change?

You could disable the udev rule with something like:
`ln -sv /dev/null /etc/udev/rules.d/80-net-name-slot.rules`
