1. If I run an XP virtual machine under Windows 7 Pro what hardware id will that virtual machine have?
2. Will it have a different hardware id every time I bring up the xp virtual machine.
3. If not, is there a way to change or specify what hardware id that machine will have?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

It will have as per below:

1.  CPU same as what you have on the computer
2.  IDE H/D controller
3.  Video card will be using drivers provided by your hypervisor
Gary CaseRetiredCommented:
The answer depends on which hypervisor you're using to create the VM.

For example, Microsoft's original Virtual PC emulates a 440BX chipset, S3 Trio Video card, a DEC 21140 NIC, and a SoundBlaster 16 ISA PNP sound card.

VMware uses a couple different chipsets, depending on the specific product; emulates a Create AudioPCI sound card, and has their own "VMWARE SVGA II" card and drivers for video.

If you're referring to the HAL, it will be either an ACPI Uniprocessor PC or an ACPI Multiprocessor PC, depending on how many CPU's you expose to the OS when you install it [The hypervisor allows you to set this].

The ID will be the same every time you start the VM, although there will be changes in the basic system ID info [Mac address, etc.] if you COPY the VM to another location and run multiple instances [MOVING the VM will not result in these changes].

It will have a virtual id. It will have very different hardware to the Host PC, but the CPU will be the same, because the Virtual Machine dectects and uses the CPU of the host.

But once you create the Virtual Machine, it will remain the same through reboots, power-ups, unless you delete it, and create a new one.

HOW TO: Select the right answer to "I Moved It" or "I Copied It" in VMware vSphere (ESXi)
Gary CaseRetiredCommented:
Andrew's article gives more detail on exactly what changes when you COPY rather than MOVE a VM.    The key difference is that if you COPY it, you can use both instances at once.    Note a side effect of this is that a COPY will require re-activation of Windows; whereas a MOVE does not, since the basic elements of the system haven't changed.
