We have a couple of customers with ARS ITSM 7.6.04 under VM's, using VMWare
VCenter Server and ESX Server. As far as now we haven't faced issues regarding
performance due to using VM's.
BMC supports VMWare and Hyper-V environments.
If your Vm's have all virtual resources (Disk, RAM, CPU) dedicated, there
should be no problem in deploying ARS ITSM. But if you have several VM's
using same resource pool, you may need to consult to VM's Admin in order to
ensure overall performance. If you're using VMWare Workstation you can
reserve resources i.e minimum 2 GB and 3600 MHz (sum of frecuency for all
processors dedicated to VM)
There´s a concept in Virtualization named Memory Balloon which refers to
real time assigned Memory vs. declared assigned Memory per VM. Your VM
could have 8 GB assigned but meanwhile it's not using all memory assigned,
host's memory will be assigned to another VM. In simple words, memory is
assigned On Demand regardless declared assigned memory. If you have not
configured Memory Baloon in a well manner you would face disk pagination which
makes VM slower.
Here´s a white paper
http://www.usenix.org/events/osdi02/tech/full_papers/waldspurger/waldspurger_html/node6.html
for understanding Memory Baloon.
Also your VM's admin may consider using Virtual Switchs for grouping all VM's
related (ARS, DB, MidTier) in order to ensure network performance.
Finally you may want to consult your DBA in order to ensure Database
Performance in VM's (assuming your DB is virtualized too)

Might want to check the compatibility guide. Different VM's are fully or
partially supported. Also
Known incompatibilities for virtual environments
BMC recommends against running server components of BMC Atrium technologies or
BMC Remedy
IT Service Management applications within VMware Workstation in a production
environment.
FYI

I would also be interested to hear from others running production systems on
VMs. My company is pushing hard for all new systems to be on VMs; but something
about sharing resources and bandwidth I do not like.
I am running a 7.6.04 64bit POC setup on VMs and it is as fast as molasses
(with a user load of 1).

Subject: 7.6.04 sp1 server specs
I just upgraded my dev server to ITSM 7.6.04 sp1 on a VM box with 2
processors and 8 gb of ram.
We are running SQL 2008 on it's own server.
This setup is really slow so it concerns me what would happen if I move
to a VM for production.
I'm curious what others are using that are running a production version
of ITSM 7.6.04 on a VM.
Are you experiencing any response issues?
What type of hardware setup are you using?
Thanks for your input.
Larry B.
