System test frameworks for scale testing on physical and virtual systems

I'm searching for a framework for running system tests. The requirement are:

• Able to manage provisioning to multiple physical machine
• Able to manage provisioning to multiple virtual environments (AWS, Azure, etc)
• Able to run tests on a given machine be it physical or virtual.
• Not bound to a single language or platform. (The product(s) is cross platform)

Is there anything that meets those requirements?

Thank you!
