VM Bus Traffic Test

Child partitions do not have direct access to hardware resources, but instead have a virtual view of the resources, in terms of virtual devices. Any request to the virtual devices is redirected via the VMBus to the devices in the parent partition, which will manage the requests. The VMBus is a logical channel which enables inter-partition communication. The response is also redirected via the VMBus.

Using this test, you can measure the level of activity on the VMBus.

Target of the test : A Hyper-V / Hyper-V VDI server
