Virtual Server Guest OS Isolation / OEM-license problem

Source: microsoft.public.virtualserver

Message:

Hello all,

I was wondering to which extent the different virtual machines and the host
operating system are isolated from one another?

To give an example, let's say I want to configure the host operating system
to act as a gateway for the guest operating systems and the other computers
I have attached to my network.

The host computer has 2 NIC's available, one of those is connected to the
WAN (internet), the other one is connected to my LAN. I want the guest O/S
to belong to my LAN, so they need to be forced to pass through the
WAN-interface on my host computer.

It is my intention to install Virtual Server onto my existing Windows XP
Professional (OEM), and host one or two Ubuntu Linux as guest operating
systems.
These guest operating servers would then serve as internal LAN-servers, and
by means of Internet Connection Forwarding, they would also act as limited
(experimental) webserver to the internet.

The most important thing about virtualisation for me is to have the host
computer as internet connection gateway / firewall.

Can this be done?

Therefore another option was to reinstall my computer with a Ubuntu Linux
Server O/S, with VMWare Server installed as well. I would then install
Windows XP Professional into a virtual machine. The problem with this is I
don't know my OEM-license key will work during the installation...

(But here the same question remains, can traffic be forced through the Host
OS before getting to the Guest OS'es?)

Thanks,

Jan

Hi Zeon,

Provided that you have sufficient ip adresses for the three machines, they
can work fine together in one network. If you want to set the host as
gateway, that is no problem.

To see whether your OEM license works on a normal Windows XP installation
(which it should). Why not first try to create a new virtual machine on
wndows xp, type in your key and see whether things are fne.

After that you can always decide which machines to virtualize and which to
'physicalize'.
Regards,

Niels

To make sure my OEM-key doesn't work, I made another attempt in contacting
Microsoft, and they replied with the same answer... too bad, because you
don't change machines/equipment... It sounds like a "flaw" in their
licensing however.

If it would have been on other equipment, i'd fully agree with them, but for
cases like mine, i don't think they fully caught that. It's like buying a
system with Windows XP preinstalled on it from a vendor like HP (or even
your local pc shop that assembled a computer for you). It is my choice to do
whatever I want with that system (install Linux/Solaris/...), as long is i
can go back and install my OEM-key again on the same hardware...

ThSo they told me to buy a full license of Windows XP, but it occurs to me
that that type of license doesn't give you the right to endlessly install
again and again (speaking in words of system crashes), as you have to
reactivate your key by calling them (and by providing a valid reason for the
reinstall). The only thing about it is that you can take your license with
you to another computer (given that your previous installation is
"erased")...

Anyway, thanks a lot for your comments, it made the other things i asked for
very clear!

Zeon,

I doubt that you would be able to get this running smoothly using ICS
(Internet Connection Sharing). It works with RRAS, but that needs a Server
OS. You could probably get it working on XP with third party NAT software
like Sygate.

There is no isolation provided just because you are using virtual
machines. You need to regard each vm as if it was a "real" machine. But it
is possible to run the vms on a private virtual LAN isolated from the WAN
(just as you can with "real" machines and a "real" hub/switch).

An OEM licence is tied to a particular piece of equipment (ie your host
machine). It is not valid for any other machine, real or virtual.
