Virtualized Servers for Performance Testing

We have to do benchmark testing as well as stress testing. Already high performance system was purchased and virtual machines are created for performance testing setup. I can see few limitations for this approach, since production boxes all are in physical servers. Earlier I've used virtual machines for automation regression execution.

  2. Increasing the risk of deployment failure

Did a google search and found following links, which give all the details, including Vmware claims.
