Does Hyper-V Handle Network Traffic Efficiently Between VMs?

  • 772

If I have network traffic between two VMs on the same Hyper-V host does the traffic actually ever leave the host server? How can I tell?

    Yes, and in fact it is very efficient between parent OS and the VM's too.

    The reason is that it setups up a virtual switch which all use and pass traffic that way without needing to go via the network cards/interfaces.
