Based on your previous emails to the list, it seems like you do not have
quantum/neutron configured.  If so, it would not be a surprise that DHCP
requests are not getting through.  What vSphere compatible Neutron plugin
are you using, and have you tested to make sure basic L2 connectivity
exists?  If it does, you should be able to manually configure IPs on two
VMs on the same network and have them ping each other.
