I would make the AD its own VM. On the off chance that you need to do
something with AD that requires a reboot you don't have to reboot everything
(also makes life easier in the future) The one caveat to this is you want
to set the priority so AD boots before Exchange (I assume hyper-v gives you
this ability).

Subject: Virtualisation structural question
Hi chaps.
Can I kick some thoughts around here and look for some comments?
We have a few old servers that we need to upgrade to new versions. Basically
we will be upgrading several Windows 2003 servers running file services, AD
and Exchange 2003. We will be replacing these with 2008 64bit R2 servers
running Exchange 2010.
As running Exchange 2010 on a DC isn't recommended (though it appears that
it isn't not-supported as such) we are looking at having two servers; one
for AD and file roles and one for Exchange roles. Clearly this lends itself
to virtualisation quite nicely with both 'servers' running on a parent host.
The question is really this: Should the AD/File roles run in a VM or on the
parent host itself, with Exchange being a child VM on the parent host ?
So this;
Physical Host: VM-HOST1
Roles: Hyper-V Host
Domain: Workgroup
VM Name: AD-1
Role: DC/GC/FILE
Host: VM-HOST1
Domain: MYDOMAIN
VM Name: EX-1
Roles: Exchange 2010
Host: VM-HOST1
Domain: MYDOMAIN
Or this;
Physical Host: VM-HOST1
Roles: Hyper-V Host, DC/GC/FILE
Domain: MYDOMAIN
VM Name: EX-1
Roles: Exchange 2010
Host: VM-HOST1
Domain: MYDOMAIN
My feeling is that the former is neater, that is with both the AD server and
the Exchange server being VMs on a parent host, than the latter.
Any suggestions? How are you chaps structuring things ?
Olly
