individual conguration. For example on the A1010

congured with 3 GB of memory, with ve VMs, each

user’s simulated performance was ne. But when

the sixth VM was added to this memory congura-

tion, the system was unable to support the load.

4. Standards for Virtualization Performance Testing

Currently, there is no industry standard for perfor-

mance measurement. While at least three proposed

standards exist, none have been ratied as a formal

industry-wide specication.

The Standard Performance Evaluation Corpora-

tion (SPEC) has formed a working group to study

the virtualization performance testing and to de-

velop a measurement technique. The SPEC work-

ing group is young, created in October 2006, and

has not produced the standard or the methodol-

ogy. View SPEC’s most recent information at:

VMware has conducted some research and has pro-

posed the VMware Benchmark. The benchmark, cre-

ated by VMware employees, is not VMware specic

and is targeted to become an industry benchmark.

VMware is working with SPEC and SPEC-member

companies to standardize this effort. As of Febru-

ary 2007, the VMware benchmark was in beta. See

www.vmware.com for more details.

IBM and Intel have also proposed a performance

benchmark christened as Vconsolidate for SPEC.

In the past, performance benchmarking from these

two companies has typically targeted very high-end

“ultimate” server congurations.
