  • Hi,

    Assuming the operating system to be windows 2012 R2 there is a hotfix for the same

    Install hotfix KB3031598

    This problem occurs because the VmSwitch assumes that the default processor for VMQ is zero (0) when it performs VMQ allocation. This causes some network adapter drivers to reject the allocation and generate Error 113.

  • Hi, Thanks and I also found this on previously. Unfortunately the HyperV I am using is HyperV 2016.

  • Hi,

    Then you can disable the VMQ for the less critical VMs or less network intense VMs. Because, the VMQ queue is exhausted.

    you can check the number of VMQs offered by the NIC by running the following powershell cmdlt

    gwmi –Namespace “root\virtualization\v2” –Class Msvm_VirtualEthernetSwitch | selectelementname, MaxVMQOffloads

    you can also check the number of queues using the following cmdlt

    Get-NetAdapterVMQQueue

    you can compare and get the difference in the queues

    Accordingly you can disable the VMQs in the VMs

  • Hi Bala,

    I think the VMQ is not exhausted because I have only ONE virtual machine in this test environment.

  • Hi,

    Still you can check the number of VMQs supported by the physical NIC from OEM and compare with the used VMQ queue. If you are using multiple vNICs in single VM and if you have vNICs used by the host operating system will also be counted

  • Hello Alexander,

    Where did you retrieve this event log? It looks like that the event log was got from a remote computer, not the Hyper-V host.

    Could you please get the event log for Event ID 113, and check out the detailed description for this event?

    Based on the current event log, it said clearly that 'The description for Event ID 113 from source Microsoft-Windows-Hyper-V-VmSwitch cannot be found', not the Vmswtich can't be found.

    Best regards,

    Andy Liu

  • Hi,

    Did you ever resolve the issue of the 113 events being logged please?

    I am getting the same errors on a newly built windows server 2016 hyper-v cluster with only 1 x VM.

    Thanks,

    Emma
