Network renaming (allowing you to have eth0 instead of en0s3..) was
broken in Beta2, this might explains why you were stuked.

This will be fixed in Beta3 and for Beta4, we will probably ship a
script to ease the creation of 70-persistent-net.rules based on MAC
address or bus address of the adapter.

For the documentation on the network precitable names, you can have a
look at
http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/ as a initial step.
