title: Unable to create AKS cluster in westeurope location
body: <p>Trying to setup an AKS cluster using this guide in the westeurope location but it keeps failing at this step.</p>
  
  <p>When executing this command <code>az aks create --location westeurope --resource-group &lt;myResourceGroup&gt; --name &lt;myAKSCluster&gt; --node-count 1 --generate-ssh-keys</code></p>
  
  <p>I continuously get the following error message:</p>
  
  <p><code>Operation failed with status: 'Bad Request'. Details: The VM size of Agent is not allowed in your subscription in location 'westeurope'. Agent VM size 'Standard_DS1_v2' is available in locations: australiaeast,australiasoutheast,brazilsouth,canadacentral,canadaeast,centralindia,centralus,centraluseuap,eastasia,eastus,eastus2euap,japaneast,japanwest,koreacentral,koreasouth,northcentralus,northeurope,southcentralus,southindia,uksouth,ukwest,westcentralus,westindia,westus,westus2.</code></p>
  
  <p>Even when I explicitly set the VM size to a different type of VM I still get a similar error. For example:
  <code>az aks create --location westeurope --resource-group &lt;myResourceGroup&gt; --name &lt;myAKSCluster&gt; --node-vm-size Standard_B1s --node-count 1 --generate-ssh-keys</code></p>
  
  <p>results in:</p>
  
  <p><code>Operation failed with status: 'Bad Request'. Details: The VM size of Agent is not allowed in your subscription in location 'westeurope'. Agent VM size 'Standard_B1s' is available in locations: australiaeast,australiasoutheast,brazilsouth,canadacentral,canadaeast,centralindia,centralus,centraluseuap,eastasia,eastus,eastus2euap,japaneast,japanwest,koreacentral,koreasouth,northcentralus,northeurope,southcentralus,southindia,uksouth,ukwest,westcentralus,westindia,westus,westus2.</code></p>
  
  <p>It looks likes creating an AKS cluster in westeurope is forbidden / not possible at all. Anybody created a cluster in this location succesfully? </p>
