(Ugh, another post not showing up)

Maybe I'm being too simplistic with my thought process here.

Currently I have a handful of SBS2003 boxes where I have either
Virtual Server running or VMware. I use the virtual machines to host
legacy operating systems that are required by third party
applications or test environments. So I am already very familiar with
quite a few of the benefits of virtual computing. I also have for my
own use Server 2008 w/ Hyper V that I also use for test environments.

Only in the later case is the real Virtualization technology making the most
of the hardware. By using a very thin and minimal resource Hypervisor
technology you can acheive the most with the least and "waste" the least on
the Virtualization software.

Put up Hyper-V in Server 2008 core or HyperV server for the slimest layer
pressently possible.



In both of these scenarios one thing has remained constant, the more
operating systems you are running, the less resources you have.

So, I was really hoping that SBS2008 would support being a virtual
host so that I could continue doing exactly what I had been doing
with either Virtual Server or Vmware. One example I had in mind for
my first SBS2008 roll out would be one machine running SBS2008 and a
virtual copy of Server 2003 that is used for their third party
application. TWO instances, one actual and one virtual.

Now, if I want to go the "supported scenario" route, I will have to
run Server 2008, and virtually run SBS2008 and Server 2003. Going
back to what I said, there have to be less resources left for each OS
since we have THREE running.

What I will instead do is run SBS2008 and Vmware. This way I can have
just TWO operating systems going, and not take that performance hit
of having yet another OS running.

YES, I know Hyper-V does some fantastic work in virtualization and
making system resources available to the operating systems that need
it. Vmware does a very good job of this as well. From here only doing
a direct benchmark and doing a full TCO comparison will really tell
us much of anything. But until someone shows me different with real
numbers, my experience and basic reasoning tells me that I will get
better performance from running two operating systems than I will if
I run three.

Again, supported solution non withstanding.

The better performance statement is yet to be seen.

Server 2008 running a virtual instance of SBS2008 and a virtual
instance of Server 2003 versus a hypothetic sbs2008 with a virtual
instance of Server 2003. On paper at least it looks like the one
machine running one virtual machine would see better performance
than the one machine running two virtual machines.

"Supported scenario" non withstanding, the choice to not let SBS2008
be a host will drive me to VMware.


Not withstanding the unsupported (currently) nature, how is a VMware
choice any better?

You'll get better performance and be in a 'supported scenario' if
you run the hardware as Windows Hyper-V Server and virtualise SBS.

I can not stress how much I love the MVP support around these
parts.

However, writing this off as a "non-issue" is a little flippant.
It is an issue for those of us that wanted to use SBS2008 has a
virtualization host as
well.

This idea that SBS is not good for being a virtualization host is
one of the
most frustrating things I've experienced over the years here. The
beauty of
SBS since the early days is that you could get big boy toys down
to one server. Virtualization is one of those big boy toys that
needs to come home
to the small office, and it is a shame that MS is not supporting
it in SBS2008. If my machine has the resources and the ability, I
should be able to
run it.

And I will run it, but unfortunately it will be with third party
software.

MS have released 'Windows Hyper-V Server' as a free download.
This is a base
installation which only allows features relating to
virtualisation. SBS08 is
fully supported in a virtual environment.

Either you need one Windows Server license (SBS) and you run it
physically
on the box (OK, people discuss virtualisation as a DR strategy,
validly) or
you need at least one additional server license and in Server 08
you get '1+1 rights' so that the one license can be used as both
host (only roles supporting virtualisation) and a full
implementation, or you use WHVS for the host.

SBS has never been a desirable virtualisation host, it's doing
enough already.

Thank you Cris.

I suspect that in the cases where we are going to have just one
server and
not wanting to purchases SBS2008 premium we will simply use
vmware :(

I was really hoping that SBS2008 would support being the Host OS
w/ Hyper-V.

Thank you Cris.

So I won't be able to use Hyper-V on my SBS2008 machine so
that I could
have
one SBS2008 server and have other virtual servers running on
it. I have
to
start with Server 2008 and virtualize the sbs2008 session.
