64-bit Confusion

I'm currently using Virtual PC 2007 and Virtual Server 2005 and want to run a
64-bit O/S in a virtual environment. Isn't a 64-bit hardware architecture
required to run a 64-bit O/S, real or virtual? Could someone help me out her
or direct me to a source for questions?

The only Microsoft product that allows a 64bit environment is Hyper-V.
VPC and VS will run on a 64bit host, but only allow 32bit VMs.

You could try VirtualBox, the new version supports x64 VMs. VMWare
does also.

But, for any of these, you need to have 64bit hardware underneath.

You still need a CPU that is 64bit capable.

no problem, I wasn't clear in my original response either!!

So, to recap:

You can run a 64bit guest OS (VM) on a 32bit host OS, provided that
your underlying hardware is 64bit capable (x64, not ia64).

Yeah, the Mac Minis are artificially limited. Heaven forbid Apple has a
powerful, reasonably priced machine.

Neither VPC2007 nor VS2005 supports 64-bit guests, regardless of the CPU(s)
on the host machine...

For that, you'll need a different virtualisation technology such as Hyper-V
or VMWare...

Not possible to do with VPC2007 or VS2005. None of these can run 64

You need to look at Microsoft Hyper-V or VMWare products instead.

So long as you're using VMWare... :-) I'm not aware of any other

And, just to add to the confusion, VMWare Fusion claims to be able to run
64-bit guests so long as the Mac host has a Core 2 Duo or Xeon processor:
http://www.vmware.com/products/fusion/faqs.html. However, this appears not
