It's most common for the hosting to look like a bridge/network switch as far as the networking goes. Thus each guest has it's own virtual NICs, each with it's own (hopefully) unique MAC address, and DHCP should "just work" to the guests.

You can run with NAT on the host - but then you need to make DHCP work through the NAT. Or you can use a routed setup where the guests are in a different subnet - in which case you'd need a relay agent as you would in any other routed network.

I'd suggest you take a look at the networking side of you proposed setup and see what you will actually be using - I'd expect it top be one of the above. If not, then come back with more details.
