    Hyper-v guest internet connection lost after booting as VHDX.


    Hello,

    I am running Windows 10 Pro (10240) and have a guest Windows 10 VM (10528) which were working fine. Both were activated and connected to internet correctly.

    Today I booted the VM as native boot VHDX. This installed some drivers, connected to internet and activated. When I boot back into host and run the VM as a guest however internet access is limited.

    I am connected in the guest to the Ethernet Microsoft Hyper-V network adapter but have no internet and so the license has switched back from activated to Notification mode. I can connect to internet through the external switch on the host and connect through RDP to the guest fine.

    Any ideas?

    :)

    th2_release Enterprise 10586 fails

    The only workaround really is to create a Hyper-V VM, attach your vhdx and then upgrade it.

    You can't upgrade native boot vhdx.

    th2_release Enterprise 10586 fails

    It is the intended behavior according to here
    Frequently Asked Questions: Virtual Hard Disks
    "Upgrading the operating system booted from a VHD. If you boot from a VHD, you cannot upgrade the Windows version in the VHD to a newer version."

    You can both native boot and run the same vhdx in hyper-v (I do). If you have 2 installs on vhdx you can use each one to update the other... Otherwise with a normal install (not vhdx) on the same hardware you can install hyper-v, create a VM using the
    existing vhdx and then upgrade it.

    No idea the reason for the restriction but it has always been like that as far as I know.

    Hyper-v guest internet connection lost after booting as VHDX.

    Problem was DNS had been lost on IP4 properties of Hyper-V adapter for some reason (I use static IP). Added it back and it is OK now. Can switch back and forward from native boot to VM and both work fine and are activated.
