It is available from the Standard Performance Evaluation Corporation (SPEC).
[1] The SPECvirt_sc2010 benchmark measures the maximum number of workloads that a platform can simultaneously run while maintaining specific quality of service metrics.
Each workload, called a tile, consists of a specific set of virtual machines.
[2] In addition to generating results that show performance, the benchmark can also be used to generate performance per watt results.
The SPECvirt_sc2010 was not supported by SPEC from February 26, 2014 [3] and its successor is SPECvirt_sc2013.
