Renaming ethernet interfaces from “p1p1″ to “eth0″

Just edit /etc/default/grub and find these lines;

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

Add biosdevname=0 to them;

GRUB_CMDLINE_LINUX_DEFAULT="biosdevname=0 quiet splash"
GRUB_CMDLINE_LINUX="biosdevname=0"

Then run ‘sudo update-grub’ and reboot. Good to go!
