    Hyper-v fails to import VM


    My Hyper-V storage drive broke down, have backups for that drive, so I have files for VMs. Replaced drive copied files from backup but Hyper-v manager doesn't see any VMs. Trying to import VMs from those files gets me error Unspecified error (0x8004005).
    Both Restore and Register Import options fail Copy succeeds but it says that it will create new ID is that bad? If windows license is tied to that VM will it require reactivation?
    Any ideas why import fails, maybe because it was disk failure Hyper-v still somehow remembers VMs that was on failed drive and dont let me import same IDs? Get-VM doesn't show any VMs also Hyper-v Manager shows up empty.

    Hyper-V Broken after Feature Update

    Hello,

    Last night the "Feature Update" for Windows 10 installed on my workstation (while I was asleep) and this morning after the reboot, most of my Hyper-V VMs are no longer appearing in Hyper-V manager.

    I've done some research and tried a number of different thing suggested on various forum posts and I can't seem to get even a fraction of my VM's back up and running again.

    It looks like a reboot was forced without shutting down the VM's first which has somehow corrupted my environment. I'm seeing unusual behaviour such as:

    a) I can re-import some VMs back into Hyper-V and they run fine.

    b) Other VMs fail to import.

    c) Some VMs import successfully but fail to start.

    d) Most unusually, some VMs import successfully but after importing they are not shown in the list and they cause other completely separate VMs being removed from the list.

    Has this update not only destroyed my machine but half of the virtual machines I've got running on it? Any advice on what I can do to recover?

    Regards,

    Keith

    Hyper-v fails to import VM

    Exporting VM with hyper-v


    Exporting a Hyper-V vm keeps everything, GUID always remains the same, original. It's the importing that determines if old GUID and for instance activation will be kept or not.

    If imported registering vm in-place or restoring vm, GUID is kept (green highlight in screenshot below). If importing copying vm a new GUID will be created (red highlight). See tutorial Method One Step 6 for explanation for these three import methods: Hyper-V Virtual Machine - Import in Windows 10 - Windows 10 Forums
