    Exactly the same issue after 24H2 update, there are no actual resource problems, got plenty of free ram and any other resources, worked fine prior to update.

    I've suddenly started hitting this issue as of yesterday. I have never seen this before in my life. None of my VM's will start. They say:

    'VM Name' failed to start worker process: The target device has insufficient resources to complete the operation. (0x80070142).

    My system has TONS of resources and never had this issue. This isn't a resource issue for sure.

    We have the exact same issue after update 24H2. Analyzing it further, it turns out that multiple VMs cannot share assigned CPU cores anymore. Giving two VMs each max 50% of the cores works. Giving one VM just one core more prevents starting it with "insufficient resources".

    This restriction can't be intentional, can it? It's a very hard breaking change and can cause entire usage scenarios to become impossible.

    System runs: Windows 11; plenty of RAM, sufficient for multiple VMs.
    Same configuration started yesterday just fine, before the update.

    Hi Mike,

    Hope you're doing well.

    The error message "the target device has insufficient resources to complete the operation" in Hyper-V version 12 often indicates that the host machine or the target device does not have enough resources to perform the requested operation. Here are several steps you can take to troubleshoot and resolve this issue:

    1. Ensure that your host machine has enough CPU, memory, and disk space available. You can check this using Task Manager or Resource Monitor.
    2. Make sure that the virtual machine is not allocated more resources than the host can provide. Adjust the VM's memory, CPU, and other resource settings to ensure they are within the host's capabilities.
    3. If you are using GPU partitioning or pass-through, ensure that the GPU has enough resources to be shared among the host and the VMs. This can involve adjusting the settings in the Hyper-V Manager or checking the GPU's usage in the host system.
    4. Close unnecessary applications or services running on the host machine to free up resources. Ensure that there are no other VMs consuming excessive resources.
    5. Check the configuration of the virtual machine for any misconfigurations or settings that might be demanding too many resources.
    6. Ensure that the storage subsystem (e.g., disk or SAN) has sufficient I/O capacity and that there is no disk contention. High I/O demands can also lead to resource insufficiency errors.
    7. Check if there are any network-related resource constraints, especially if the VM operation involves significant network traffic.

    Best Regards,
