Hyper-V / Server 2016 host is crashing when VMs start for first time RRS feed

  • Question

  • Like the title says, We are having an issue with our hyper-v host servers crashing on the initial startup of guest vm's. 

    Everything works fine during the creation of the guest vm, then when we go to power up the guest vm about 10-20 seconds later the host crashes. Doesn't happen on every vm setup, but quite a few (say 1/3). 

    I have found examples of others having the same issue or similar. See https://www.youtube.com/watch?v=ytP-RfhdBWY  (not my video, but same sort of issue).

    I haven't seen anything in event viewer that would indicate a problem with the host. no crash logs are saved when it does crash, just a hard black screen (no BSOD). 

    Any thing you guys can point me to look for here? I am at a total loss on this. 

    Thanks,

  • Hi,

    Thanks for posting in our forum!

    Before we move on, would you please help me clarify the following information?

    1.What the version of your problematic VM?

    2.Are there any differences in settings between the problematic virtual machine and the normal virtual machine? Can you provide a screenshot of both settings?

    3. Has the problematic VM changed recently? Updates and so on.

    Thanks for your time.

    Best Regards,

    Daniel

  • To answer your questions.

    1. Windows Server 2016 Standard

    2. No differences, all servers are created from syspreped templates using a powershell script. we have 1000's of vm's created from these templates. Some crash the host server on initial startup while setting up drivers, and some don't.

     3. No, updates are done quarterly on all templates and this issue has been ongoing for a long time. Again, it's not the VM crashing but the HOST SERVER that is crashing. 

    Thanks,

  • No issue hasn't been resolved. No change in current situation. Still when creating vm's from templates the host has a about a 1/3 chance of crashing. 

    Happens on all of our host systems, so not isolated to one server.

  • What is the host configuration?  Is the hardware supported for whichever version of Windows Server you are using?  www.windowsservercatalog.com

    Does the problem occur if you manually create a VM from the template instead of using your PowerShell script?

    Does the problem occur if you create VMs without using the sysprepped template?

  • Hi,

    Thanks for your reply!

    Is it possible to do a test, shut down all VMs, and then only start a problematic virtual machine to see if the host will crash.

    In addition, you can also check it out from Tim's suggestion.
