Excellent. Thanks Sorin/Angus.
 
I've gone for MS VS as a starter.

Dual-cores and dual-cpus are great for virtualisation! I have a amd
x2/4400. It's awesome when running the virtual machines. I also have 2GB
ram installed, would need another 2... Runs fine/ok now though with
about 3-4 VMs. Bigger experimental setups would need more ram.
 
In my environment and my opinions:
 
Xen: Demon on speed in a rush. Runs all OSes I know of. Never tried this
though, but hear it's good.
 
MS VS: Speed demon. Runs all windows-versions. Doesn't do anything *nix
AFAIK.
 
VMWare VS: Slightly slower than MS's VS. Better interface though
(tabbed). Doesn't run Win2k (at least mine doesn't, refuses install for
some reason). Does everything *nix.
 
I have both MS and VMW VMs installed.
 
HTH.

I have an old citrix server which has a couple of gbs of RAM but only a
few p3 1.8's in. I was thinking of using that, would that do? When
talking software which is the best I know MS do virtual server and then
there's VMWARE. Any recommendations?

If you can rake together the hardware (it doesn't have to be high spec
for testing but lots of memory is a good idea) it's worth doing,
especially now that decent virtualisation software is available for
free.

        The way I see it is that it's kind of going back to how it was
when hardware was really expensive, so you had to have one server
running multiple apps/roles. Then when hardware got cheaper, esp discs
and memory, all the roles were split up to single machines, at least in
my experience.
         
        I guess I still have a slight fear about running a lot on one
machine, (I know the machines are hardly comparable with then and have
redundant discs/power/nics etc), but I really could do with getting one
running as I said for a lab machine with a citrix box and a few other
bits and bobs like WSUS etc.
         
        Thanks for the info.

        We run a couple of low-use Citrix servers (<5 users but a very
fussy app), a PDC and BDC for a legacy NT4 domain, pairs of servers (on
different physical hosts) supporting various in-house developed systems
and a variety of similar machines. I would be happy to run
mission-critical servers on VMWare now that I have more experience and
confidence in it but all of our critcal systems are heavy-use.
         
        On the desktop I use VirtualPC to run all sorts of legacy
machines for software testing and development.

                So you're running non mission critical servers, I like
the idea of virtual servers but most of ours have mission critical apps
on. I like the idea for lab machines though! 
                 
                Cool.

                The physical servers have lots of built-in redundancy
and I wouldn't class any of thevirtual servers as enterprise-critical.
In the event of a physical failure I can copy the important ones back
from tape (each server is only a handful of files) to another server (I
have a lower-spec server for development) and bring them back within a
few minutes.

                        What happens though if a server fails? Haven't
you put all your eggs in a few baskets?

                        I've got a couple of beefy Quad-Xeon, 12GB RAM
machines running about 30 servers in total.
                         
                        The main benefits are I can provision low-use
servers without wasting hardware and I can provision them quickly,
typically less than 10 minutes from deciding it's needed to having it
available on the domain for use. They are also easy to backup and move
to another host in the event of a hardware failure, although I've yet to
have one.
                         
                        Running VMWare GSX 3.

                                How many of you are now using either
server virtualization or storage virtualization (or both)?
