Not getting an IP via DHCP doesn't mean anything but there might be a
software fault. First, does it work at all? Assign it an IP address by
hand and then try pinging around.

Also you can do this:
hakan at jupiter:17:26:30:~$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp

More than once, esp. on my cloned VMs, Ubuntu decides to add a 2nd
card and then forgets all about it.
