This is an attractively elegant idea, but in many real clouds the 
minimum cost of a VM is quite high and thus it would be a waste to use a 
VM for something like DHCP.

Also, if the cloud doesn't support DHCP, how can you create multiple VMs 
from a single disk image? You can't configure the image with a static IP 
address because then you'd have multiple VMs with the same address, and 
you can't configure the image with no address at all because then you 
wouldn't be able to log in to set the IP address.
