I'm fairly new to Hyper-V, and can't seem to find the answer to this question:
Do two virtual machines on a single Hyper-V host use the NIC when communicating with each other?
For example, take this diagram:
Does the communication between the web and DB VMs go through the physical NIC, or is it able to communicate through the virtual switch without going over the physical NIC?
Also, does SR-IOV have anything to do with this, or is this more to do with going over the NIC directly without going through the host (as in the diagram on this article)?
Ideally, I'd like to see references to actual documentation explaining this, as I've searched, and can't find anything one way or the other.
