Does Microsoft support using the Extended Security Updates Azure Benefit for Azure Stack HCI on generation 1 virtual machines? Cause I have several gen1 VMs that are all failing with the following error:

 Add-AzStackHCIVMAttestation -VMName SRV -Force
	Unable to configure IMDS Service on VM. 'SRV' failed to add resources to 'SRV'.
	
	Cannot add device 'Synthetic Ethernet Port' while the virtual machine is running.
	
	'SRV' failed to add resources. (Virtual machine ID )
	
	'SRV' cannot add device 'Synthetic Ethernet Port' while the virtual machine is running. ()

    Hi,

    The error above indicates that the adapter cannot be added to the VM when it is in a running state. I confirmed within my lab that attempting to add an adapter to a running Gen1 VM using the Add-VMNetworkAdapter cmdlet fails with the same error. 

    PS C:\> Add-VMNetworkAdapter -VMName Test -SwitchName "TestVSwitch" -Name Adapter1 

Add-VMNetworkAdapter : 'Test' failed to add resources to 'Test'. Cannot add device 'Synthetic Ethernet Port' while the virtual machine is running. 'Test' failed to add resources. (Virtual machine ID XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX) 'Test' cannot add device 'Synthetic Ethernet Port' while the virtual machine is running. (Virtual machine ID 1E58DFC5-4F56-47FD-A6F5-7E8165EF0435) At line:1 char:1 + Add-VMNetworkAdapter -VMName Test -SwitchName "TestVSwitch" -Name Adapt ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~     + CategoryInfo          : InvalidOperation: (:) [Add-VMNetworkAdapter], VirtualizationException     + FullyQualifiedErrorId : NotSupported,Microsoft.HyperV.PowerShell.Commands.AddVMNetworkAdapter

    I was able to successfully add an adapter using the exact same method to a running Gen2 VM.

    Based on this result, please attempt to power off the VM and try re-enabling attestation.

    Hope this helps!

    Thank you for the responses. Added the Gen1 VM to Azure benefits was successful while the VM was shutdown.

    @Jim Gandy

    If you are running Azure Stack HCI, versions 22H2 or 21H2, it should be supported, I am not aware of a generation 1 limitation. See Free Extended Security Updates (ESU) through Azure Stack HCI. See here for more details on enabling the Azure Benefit.

    Please double check that you have followed the steps there. If you are still facing issues please let me know and we can work with you directly to further troubleshoot.
