I can launch VM using New-AzVM cmdlets from a SharedGallery, a legacy image or from the marketplace, however I can't figure how to launch a VM from a Community Gallery.

Fort instance this image: /CommunityGalleries/rocky-dc1c6aa6-905b-4d9c-9577-63ccc28c482a/Images/Rocky-9-x86_64/Versions/9.4.20240509

I am getting the following stack trace:

Microsoft.Azure.Commands.Compute.Common.ComputeCloudException: Property id '/CommunityGalleries/rocky-dc1c6aa6-905b-4d9c-9577-63ccc28c482a/Images/Rocky-9-x86_64/Versions/9.4.20240509' at path 'properties.storageProfile.imageReference.id' is invalid.

I tried with:

$VmConfig = New-AzVMConfig -VMName "${ImageName}" -VMSize "${InstanceType}" -ImageReferenceId ${ImageId}

and I also tried

Set-AzVMSourceImage -VM $VmConfig -Id ${ImageId}
```

What am I doing wrong ?

Using pwsh 7.5.2, Az 14.3.0, Az.Compute 10.2.0</div>

The author also tried -SharedGalleryImageId but got this error

Microsoft.Azure.Commands.Compute.Common.ComputeCloudException: The shared gallery image reference id provided, '/CommunityGalleries/rocky-dc1c6aa6-905b-4d9c-9577-63ccc28c482a/Images/Rocky-9-x86_64/Versions/9.4.20240509', is invalid.

Hi @isra-fel - Is this only happening in PS? Does the CLI work fine? Also, can you try reproducing the issue in CloudShell in Azure Portal.

Can you use the ImageReference.CommunityGalleryImageId property ?
