Orphaned Virtual Switch / Need to reset hyper-v??? RRS feed

  • Question

  • Hi, I am using hyper-v to remotely debug some kernel drivers inside a VM as described here https://msdn.microsoft.com/en-us/library/windows/hardware/jj200334(v=vs.85).aspx

    I created a Windows 10 Pro VM and also created a virtual switch attached to a Network interface. The virtual machine could connect to the internet/Local LAN with no problems and kernel mode debugging of my driver worked without any issues.

    This all works fine, however due to incompatibilities with other software I sometimes need to disable Hyper-V, upon re-enabling Hyper-V my virtual switch was shown as disconnected, as if the interface was physically unplugged from the network, if I disabled the virtual switch and reverted back to the Host interface the internet works fine. In an attempt to fix this I probably made the problem worse, at one point the Virtual Switch Manager could not be opened saying that it was unable to enumerate the list of virtual devices.

    I have two questions

    1) How can I remove the virtual switch from my computer? attempting to use the switch manager resulted in the following error

    Switch delete failed, switch = {GUID of Switch}: The device does not recognize the command (0x80070016).

    At this point I would just like to be able to reset Hyper-V back to its default configuration and start over, if I try to disable hyper-v at this point windows reports that it is unable to make the changes and turns hyper-v back on.

    2) Is their any thing I can do to avoid these problems in the future other than just leaving hyper-v enabled all the time? When I reactivated hyper-v the first time the virtual machine was fine just the virtual switch had issues

  • Hi Ohduck,

    >>This all works fine, however due to incompatibilities with other software I sometimes need to disable Hyper-V

    Do you mean uninstall the Hyper-v role?

    >>if I disabled the virtual switch

    What do you mean by disable?

    Before disabling Hyper-V, I suppose you should remove the virtual switch in advance.

    Best Regards,
