    Is there anyway that I can create a virtual switch but without interfering with the physical network?

    network adapter fails to connect after virtual switch setup.


    If you use both Hyper-V and VPN, you should always first create the Hyper-V switches and only thereafter set up the VPN connection. Setting up a new Windows PC, this is the order to do stuff:
    • Install Windows
    • Set up Hyper-V
    • Set up the external Hyper-V virtual switch(es)
    • Set up VPN connection
    This way the VPN will start using the correct network adapter (an external virtual switch instead of a physical adapter).
     
  3. Hyper-v virtual switch breaks my network


    Glad to find this, and surprised an issue of this nature is still not fixed. I notice one work-around is missing from this thread, so thought I would add it:

    The problem: Creation of a new external virtual switch in HyperV Manager causes Host file sharing to be disrupted. Specifically, it appears that the services associated with physical adapters get set correctly, but something below the hood for File and Print Sharing gets broken.

    Solutions:
    As said in earlier posts, if the new "Default Switch" works for you, it is the least problematic option. Delete any manually created external virtual switches and set the network adapter for each VM to "Default Switch" to take this option.

    Unfortunately, you cannot assign a distinct IP address to the Default Switch. So this may not work for all users.

    Another option not discussed yet works for users with multiple physical network connections. You can use one physical adapter for the host machine, and a different one for the virtual switch. When creating the virtual switch, uncheck the box to allow the host machine to share the connection.

    You'll notice that even though this setup has the virtual switch completely separated from the host machine's networking, the host machine's file sharing still gets broken. However, simply get properties of the physical network adapter for the host machine, remove all protocols and apply. Then add them back and apply. This will restore functionality.

    Some have noted that they had to redo this every time they restarted their machine. I haven't confirmed this yet, but it is likely. Ugh.

    This solution will did not work for me with a single physical network shared with the host machine. It required adding an Ethernet port. I think if I had only one port, I would use Kari's suggestion from post #18 above.

    Creating a Virtual switch without interfering Physical network

    not able to create virtual switch


    First, here's some help with screenshots and how to post them:

    In this case now a screenshot is no longer needed. The information you posted clearly shows that you already have an external virtual switch created and assigned to your Ethernet LAN network adapter.

    In Hyper-V, you can only create one external switch per a network adapter, in other words the maximum number of external virtual switches is 1 if you only have one Ethernet adapter, two if you have one Ethernet adapter and one wireless adapter, and so on.

    As you already have the external virtual switch assigned to your Ethernet adapter, you cannot create another one.
