    Unable to start Virtual Machine, Error message: "Validation" Failed to start.


    Hi,

    This errors started when a windows10 update was pushed to my windows7 laptop. I had two vms working great in windows7 now both generate the same error. yesterday i downloaded a win10 vm and it starts with the same error. i notice when any of the vms try to start they get to a status of 10% started and fail. I have tried all the suggestions in other posts; dvd, memory, network adapter, nothing clears this error. starting vmconnect in power shell started as administrator results in the same error. this seems like a permission problem but hard to figure out.

    Machines Fail to Start and Initialize


    I have already done this, many time, including restarting the PC. However, the error persists.
    These are the two errors I am now receiving:

    Unable to start Virtual Machine, Error message: "Validation" Failed to start. [​IMG]


    Unable to start Virtual Machine, Error message: "Validation" Failed to start. [​IMG]

    For public consumption, this is what I said in a PM to you. It summarizes everything, including fixing the virtualization errors. The two errors are the images above:
    My Windows 8.1 Hyper-V virtual machines worked fine. I just upgraded to Windows 10 (with the CPU virtualization turned off) and after turning virtualization back on when I attempted to start the machines (after enabling the hypervisor) I get errors hypervisor errors and "'(machine name)' failed to start." and "'(machine name)' could not initialize." errors. The same thing happened when I created a new virtual machine (which created successfully) and then start it. Initial event log errors for the Hypervisor errors have been solved. I was able to eliminate the Hypervisor issues by changing the boot configuration data store file for the "hypervisorlaunchtype" to "Auto" from "Off." Now when attempting to start a new Virtual Machine in Hyper-V Manager and start it I only get the event ID 3040 errors that the VM could not initialize and the event ID 15130 errors that the VM failed to start. All other event log entries look normal. Again, these error occur both with virtual machines that ran fine under Windows 8.1 and new ones created after the upgrade to Windows 10.

    I posted about this issue on the Windows 10 Community Forum and four other people indicated they had the same issue.

    Try this, tell what if anything happens:

    Stop the Hyper-V service, then restart it:

    Unable to start Virtual Machine, Error message: "Validation" Failed to start. [​IMG]


    When done, create a new vm and try to start it. If it does not start but gives an error message instead, post the screenshot of the expanded error message with all details, or post the full text of said error message.

    OK in this case the additional info in the error message really does not reveal anything.

    Do you store the virtual hard disks and configuration files on default places? VHD files in C:\Users\Public\Documents\Hyper-V\Virtual Hard Disks, and the configuration files in C:\ProgramData\Microsoft\Windows\Hyper-V? If so you could try this and tell if you could create and run a vm:

    • Create a folder Hyper-V on root of any drive than C:
    • On that folder create a subfolder, name it as VHD, and another with a name VM
    • Create a new VM
    • In New Virtual Machine Wizard, step Specify name and location, select Store the virtual machine in a different location, browse to the Hyper-V\VM folder you created and select it as the location
    • In New Virtual Machine Wizard, step Connect Virtual Hard Disk, click the Browse button next to Location, browse to the Hyper-V\VHD folder you created and select it
    • Finish the setup, launch the vm
