Unable to create Windows B2s nodepool in AKS-CodePudding

I need to add a Windows B2s nodepool to AKS. I am getting the folowwing error:

Error: Code="VMSizeIsNotPermittedToEnableAcceleratedNetworkingForVmss" Message="Virtual machine at index 0 of VM scale set /removed id of VMSS/ has size Standard_B2s, which is not compatible with enabling accelerated networking in the network profile on the scale set. Allowed sizes: Standard_D2_v4, Standard_D2s_v4, Standard_D2ds_v4, etc.

I am sure before this was allowed because I had created B2s and B2ms Windows nodepools before. I see it is related to accelerated networking, but how can I influence accelerated netoworking for VMSS that is yet to be created and is controlled by Azure?

CodePudding user response：

I have tested to add B2s in my environment with Linux nodepool and it was successful.

If your instance supports then it should be deployed with Accelerated Networking. If it does not, it should be deployed without AN. Please issue a support ticket if you can. And you can give these steps a try.

Create nodepool with AN supported instance type.
Scale nodepool to zero.
Change instance type to B2s.
Scale nodepool to one.

I shared a link below. Not the same thing but it also can give an idea.

Would suggest you to select the node pool which is recommended one.

You can refer this MS Document for the same information.
