No problem. That means the router will reserve the address, so you can
simply use that address as a static address in the VM. The MAC address
won't matter, and you won't have to run around changing anything.

It was going to be DHCP-assigned fixed addresses, but I made a typo entering

somewhere in the (IP, MAC) pair, and the crappy router software won't let
you fix or delete a mapping until it is active, which it'll never be because

there's a typo on it. $%*^. But I'd rather have a centralized location
from which I can employ a new NIC -> IP mapping than have to run around to
all the computers. Never mind that there are several transient computers
which may not get the word.
