VMs on Hyper-V host sometimes get freeze (stunned) and become inaccessible RRS feed

  • Question

  • Hello,

    We have been having this issue for years and have no clue how to solve. 

    We have several Hyper-V hosts (Physical HP servers running Windows server 2012 R2 ) on premises and have around 20 VMs sitting on the hosts in total. One of the Hyper-V hosts has our file server (VM Windows 2012 server R2) and sometimes the VM stops responding.

    the issue is the following:

    The VM suddenly stops responding (unable to access shared folder, RDP)

    The VM is still pingable

    We still can see "Press Ctrl+Alt+Delete to sign in" screen from the Hyper-V console but unable to log in

    When this happens, we cannot do anything so we turn the VM off from Hyper-V console (if we shut it down  from Hyper-V console, it will stuck for 10-20 mins and give us an error).

    This issue actually happens to other VMs on other Hyper-V hosts we have also.

    any help or information would be really appreciated. Thank you in advance.
