[wanglijun378617]

Hi team,

When create AKS cluster on the portal by enable virtual node, it will show validation failed with below error msg:

{"code":"InvalidTemplateDeployment","message":"The template deployment 'microsoft.aks-20201118142343' is not valid according to the validation procedure. The tracking id is 'd3522973-f6c2-434d-824c-147092f997f7'. See inner errors for details.","details":[{"code":"GetSubnetError","message":"Provisioning of resource(s) for container service testvirtualnode in resource group akstest failed. Message: {\n \"code\": \"GetSubnetError\",\n \"message\": \"Could not find subnet virtual-node-aci in vnet akstestvnet128 from resource group akstest of subscription .\"\n }. Details: "}]}

I use the default configuration of new Vnet and subnets as below, it should create the subnet automatically, right? Could you please help check?
