Vista - Supported OS guests

Hi everyone,

After reading the
http://support.microsoft.com/kb/954958/en-us and
http://www.microsoft.com/windowsserv...-guest-os.aspx e noitice that Windows 2003 can ony run on 2 virtual CPUs?

Why not 4 CPUs? Will I have performance issues with this? The funny thing is
that I never noitice that in the lab environment, and I actually can define 4
virtual CPUs for windows 2003!!! Why MS is saying that isn't possible?

What SPM stands for?

Thank you all.

It is possible, they are saying it's not supported. You can assign
4CPUs if you like, but you will not get technical support in that
configuration.
They have not fully tested 4 CPU configurations, so it's not
supported. There are no hard-coded limits, so theoretically you could
run 8 or 16 CPUs in a VM also, if you have the hardware, but it's
still an unsupported configuration.

Ok, thank you for the response, but this is really stupid... Not to say
worse... so if MS decides to not give support for 2003 with 4 virtual CPUs
they have that right because they didn't have time to to test with 4 virtual
CPUs. funny thing because looking at the competitors in Virtual world we
don't see think like this one...

No, it is not stupid. What Microsoft is saying is that we have not tested
this configuration so we cannot offer full support for it, but it will
probably work.

What are you running on Server 2003 in a vm that you think will require
more than 2 cores? Is it showing any sign of being processor bound?

That´s your opinion. But think again, when your client has to decide between
HV and other available Virtual Server solutions in the market that don't have
these limitations. I know that will work with 4 virtual cores, I already
tested, but when the client asks you why? An when the is aware that MS may
not (although I think that MS would never refuse support because of this)
provide support, this may impact in the client decision.

As for the question: what will the client will run that requires 4 virtual
CPUs, the answer is everything, and this will be a platform with lots of
physical servers that will run all Microsoft and Non-Microsoft technologies.

Then you are free to use other vendors software! What also might
impact them is the cost of the hypervisor also. So?
Everything requires 4 CPUs? If the work is so processor intensive
then why even bother with virtualization?
