Message:Hi Bo
That's why I'm installing a second one on the other machine. Machine A is
up and running and it VM DC is running. Machine B is rebooted and allowed to
attach to that DC. Once up Machine A is rebooted and allowed to attach via
the VM on Machine B.
I guess the real question is will the connections survive the reboots as
long as one of the VMs is up?

Message:You can actually run with only one domain controller in a child partition
and the parent is joined to the domain. On start up the parent will use
cached credentials. You need to set the child DC to start up before any
other children. There are other considerations as well. See Option 4 and
some of the comments in the following blog.
http://blogs.msdn.com/virtual_pc_guy/archive/2008/11/24/the-domain-controller-dilemma.aspx
It's obviously not an optimum situation and may not be something you want to
put into production. I have done this a few times while testing and for
demos. I've had a child DC with the parent joined to the domain and managed
by SCVVM also running as a child. You have to play with the timing that the
children start up with. You have to do a bit of testing to see how long it
takes the DC to start up then set the children to delay for at least this
long. Depending on your hardware it may take ten minutes or so to get
everything up and running from a cold boot. Updates can be a problem as this
may delay the startup of the DC. I've found it best to update in this
order - child DC first, parent, then the rest of the children.

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.
