I'm working on 24 server Virtualized GroupWise solution right now.   Here are the hardware specs:

6 3950 M2 IBM X Series servers (high end)
128 Gigs of memory in each Host server
4 CPUs, 24 Cores per server
SAN: IBM XIV, Tier 2 storage
CISCO 9516 SAN Switches 
4 Gig for SAN connectivity
NetWare 6.5 SP8
Running this all on a 6 node, VSphere 4 Update 1 Cluster

Supposedly, each of the X Series Hosts can handle up to 128 servers each.  

I'll let you know how it goes.

I would caution anyone against Virtualize NetWare.  It can be done and I have a few small utility type servers virtualized, but I tried virtualizing a full server with shared folder and users home directories and nearly had a mutiny because of performance.  I also tried virtualizing a server that was nothing more than the Symantec parent server for several hundred workstations.  All that they would do is get signature updates from it, nothing else.  That didn't go well either.  It had been moved back to a physical server and it working well.  We haven't gone to EPP yet we are still at Corporate Edition for SAV.

OES2SP1/SLES10SP2 has been fine virtualized with several hundred users hitting an NSS volume.

If you are worried about VMWARE perfomance on older hardware, possibly
do some testing and monitor memory, CPU and NIC utiiliztion.  Should be
present in the local VM client install.

Not sure on the novell end, (I do have a couple of OES2 in virtual,
including GW8 1000 user server) but  I have plenty of production WINDOZE
W2K8 64 bit guest VMs running on HP DL380 G5 ESX 3.5 cluster on SAN with
no major performance problems.
NIC utilization has not been an issue at my site with the onboard HP

However, if you do have the chance, "VMWARE 4"  would be the preferred
option to move to.

Hope this helps.
Thank you

I of course can use whatever I want because I'm not a big company, so I
ESXi 3.5 on a my 32 bit server, and it works very well.  On my 64bit
I'm worried that ESXi 4.0 will not work, but I need 64 bit VMs (thanks
Novell <heehee>), so I'm running Server 2.0 on that for the 64 bit VMs.
my take is that unless you need to actually have 64 bit VMs for
3.5 has been perfectly fine for my needs, which aren't as great as
large companies, but greater than most of my small company clients.
