Not sure what the problem is, but I would suggest running the dmesg | more and see if there is any messages about it starting the eth0?

You might also want to add the ifcfg eth0 command to the /etc/rc.local file so that it will try to bring the interface up as part of the boot process?

This pointed in the right direction: after upgrading fedora removed all networks from autostart leaving it up to NM to start them. This is OK for a desktop system, but not for a server no-one ever logs in at. After doing a

systemctl enable networking

all was again as expected! Thanks for the help!
