That should not happen (not saying it doesn't, just saying it
shouldn't - there is a disconnect between DHCP proper and CloudStack
allocation.) Virtually all DHCP servers check to ensure that no
conflict exists (via ping and/or arp) before handing out an address
and should remove a potential address from the pool if it is already
in use. I am not sure a feedback loop exists back to CloudStack from
that, but DHCP certainly has provisions for dealing with it.
