As with most questions regarding virtualization you can ask "what do I
do if the virtual machine is a physical machine?".
The answer invariably is the same for both.
In this case, if one host is already running and its guest is also
running and is attached to the same network as the second host then
the first host and its guest look just like two computers on the
network to the second host. If one of these is the DC of the domain
the second host is a member of, then fine, the second host will be
able to talk to its DC over the network.
