Hello Team,

We are planning to perform the live migration Hyper-V virtual machines from one host to another host (shared nothing migration) and we have followed the prerequires below.

ü Configure constrained delegation:

ü Set up the source and destination computers for live migration:

After that when we started the migration Use Hyper-V Manager to move a running virtual machine, we are getting the below error.

The virtual machine cannot be moved to the destination computer. The hardware on the destination computer. The hardware on the destination computer is not compatible with the hardware requirement of this virtual machine.

The operation failed with error code '32784'.

Note: While we perform the migration with Trun off vm it is working fine,

Windows for business | Windows Server | Storage high availability | Virtualization and Hyper-V

    Hi Obulesu,

    Hope you're doing well.

    1. Please open PowerShell as an administrator and run the following commands and provide us the screenshots:

    Compare-VM -Name VMname -DestinationHost xxx

    (Compare-VM -Name VMname -DestinationHost xxx).Incompatibilities | fl *

    1. Create a new test virtual machine (located in the CSV of the cluster) to see if it can be migrated in real time normally.
    2. Open Hyper-V Manager, right-click the virtual machine and select "Settings", expand "Processor", check "Compatibility", try to check it and perform live migration to see if it can be successfully performed.
    3. Create a new test virtual machine (located locally, not in the cluster), see if it can be migrated in real time normally (Move).
    4. Check whether the CPU and patch levels are consistent across nodes.
    5. Try to disable 3rd-party anti-virus software. (if exist)

    Best Regards

    HI thank you for your response,

    Could you please let me know where I have to run the below commands. (I have tried to run below command inside source VM as well as destination host server but getting the error)

    Compare-VM -Name VMname -DestinationHost xxx

    (Compare-VM -Name VMname -Destination Host xxx). Incompatibilities | fl *

    We removed VM from cluster and try to move to destination Host getting an error "The operation failed with error code '32784'"

    But when we turn off the VM and tried to move it to destination host it's working without any issues.

    I checked CPU and Patch levels are good on Source and destination We will try to disabled antivirus and let you know the status
