'ifconfig eth0 up' just activates the interface, but it doesn't cause
the OS to run DHCP/BOOTP or assign an IP address, and possibly set up
proper routing.  Try 'ifup eth0'.

I've always set up virtual hosts to use static IPs, or use the internall
NAT, so I can't be much help here.  I would suggest checking with the
DHCP server to make sure: 1.) it is allowed to give the virtual host a
lease.  I don't know your environment, but we don't give out IPs unless
the hardware address is registered.  2.) Is the DHCP recieving packets
from the virtual host?
