title: Failed to use the confidential computing VM deployment service in Azure
body: <p>I created an Azure account which is promised to be able to use all the services in Azure for free for a month. However, I always failed to create a confidential computing VM in the verification phase. The error report I got is:   </p>
  
  <blockquote>
    <p>InvalidTemplateDeploymentThe template deployment failed with error:

  <p>It seems no available resources exists to deploy the confidential computing VM (so strange since it contradicts to what they promise for free accounts). Changing configuration (limited configuration options) didn't work. I think it is related to configuration. According to the link provided by the Azure, this creation failure may be due to the error called 'SKUNotAvailable' and users can determin their available resources using command <code>'Get-AzComputeResourceSku | where {$_.Locations -icontains "centralus"}'</code>. Strangely, I've found that I have the resources available to deploy the confidentials for computing VM. In this case, it is not associated with the resources the Azure provided for free accounts.</p>
  
  <p>I've found another guy posted a similar problem (<a href="https://stackoverflow.com/questions/60578520/unable-to-create-a-vm-on-azure-confidential-computing-acc">Unable to create a VM on Azure Confidential Computing (ACC)</a>) which is still unsovled. He succeed to create a normal VM but failed when tried to deploy the confidential computing.</p>
  
  <p>Could anyone create the Azure confidential computing VM or provide any hints about a possible solution? Thanks so much!</p>
