Creating Azure Virtual Desktop session host VMs
Session host VMs can be created in several ways, but the Azure Virtual Desktop team only supports VM provisioning issues related to the Azure Marketplace offering. For more information, see Issues using Azure Virtual Desktop - Provision a host pool Azure Marketplace offering.
Issues using Azure Virtual Desktop – Provision a host pool Azure Marketplace offering
The Azure Virtual Desktop – Provision a host pool template is available from the Azure Marketplace.
Error: When using the link from GitHub, the message "Create a free account" appears
Cause 1: There aren't active subscriptions in the account used to sign in to Azure or the account used doesn't have permissions to view the subscriptions.
Fix 1: Sign in with an account that has contributor access (at a minimum) to the subscription where session host VMs are going to be deployed.
Cause 2: The subscription being used is part of a Microsoft Cloud Service Provider (CSP) tenant.
Fix 2: Go to the GitHub location for Create and provision new Azure Virtual Desktop host pool and follow these instructions:
Right-click on Deploy to Azure and select Copy link address.
Open Notepad and paste the link.
Before the # character, insert the CSP end customer tenant name.
Open the new link in a browser and the Azure portal will load the template.
Example: https://portal.azure.com/<CSP end customer tenant name> #create/Microsoft.Template/uri/https%3A%2F%2Fraw.githubusercontent.com%2FAzure% 2FRDS-Templates%2Fmaster%2Fwvd-templates%2FCreate%20and%20provision%20WVD%20host%20pool%2FmainTemplate.json
Error: You receive "template deployment is not valid" error
Before taking specific action, you'll need to check the activity log to see the detailed error for the failed deployment validation.
To view the error in the activity log:
Exit the current Azure Marketplace deployment offering.
In the top search bar, search for and select Activity Log.
Find an activity named Validate Deployment that has a status of Failed and select the activity.
Select JSON, then scroll down to the bottom of the screen until you see the "statusMessage" field.
If your operation template goes over the quota limit, you can do one of the following things to fix it:
- Run the Azure Marketplace with the parameters you used the first time, but this time use fewer VMs and VM cores.
- Open the link you see in the statusMessage field in a browser to submit a request to increase the quota for your Azure subscription for the specified VM SKU.
Azure Resource Manager template and PowerShell Desired State Configuration (DSC) errors
Follow these instructions to troubleshoot unsuccessful deployments of Azure Resource Manager templates and PowerShell DSC.
- Review errors in the deployment using View deployment operations with Azure Resource Manager.
- If there are no errors in the deployment, review errors in the activity log using View activity logs to audit actions on resources.
- Once the error is identified, use the error message and the resources in Troubleshoot common Azure deployment errors with Azure Resource Manager to address the issue.
- Delete any resources created during the previous deployment and retry deploying the template again.

Cause 1: Credentials provided for joining VMs to the domain are incorrect.
Fix 1: See the "Incorrect credentials" error for VMs are not joined to the domain in Session host VM configuration.
Cause 2: Domain name doesn't resolve.
Fix 2: See Error: Domain name doesn't resolve in Session host VM configuration.
Cause 3: Your virtual network (VNET) DNS configuration is set to Default.
To fix this, do the following things:
- Open the Azure portal and go to the Virtual networks tab.
- Find your VNET, then select DNS servers.
- The DNS servers menu should appear on the right side of your screen. On that menu, select Custom.
- Make sure the DNS servers listed under Custom match your domain controller or Active Directory domain. If you don't see your DNS server, you can add it by entering its value into the Add DNS server field.

Cause: The specified Azure Virtual Desktop tenant admin requires Microsoft Entra multifactor authentication (MFA) to sign in.
Fix: Create a service principal and assign it a role for your Azure Virtual Desktop tenant by following the steps in Tutorial: Create service principals and role assignments with PowerShell. After verifying that you can sign in to Azure Virtual Desktop with the service principal, rerun the Azure Marketplace offering or the GitHub Azure Resource Manager template, depending on which method you're using. Follow the instructions below to enter the correct parameters for your method.
If you're running the Azure Marketplace offering, provide values for the following parameters to properly authenticate to Azure Virtual Desktop:
- Azure Virtual Desktop tenant RDS Owner: Service principal
- Application ID: The application identification of the new service principal you created
- Password/Confirm Password: The password secret you generated for the service principal
- Microsoft Entra tenant ID: The Microsoft Entra tenant ID of the service principal you created
If you're running the GitHub Azure Resource Manager template, provide values for the following parameters to properly authenticate to Azure Virtual Desktop:
- Tenant Admin user principal name (UPN) or Application ID: The application identification of the new service principal you created
- Tenant Admin Password: The password secret you generated for the service principal
- IsServicePrincipal: true
- AadTenantId: The Microsoft Entra tenant ID of the service principal you created
Error: vmSubnet not available when configuring virtual networks
Cause: In the Azure Virtual Desktop Marketplace template, the UI only displays subnets that have at least as many IP addresses available as the total number of VMs specified in the template. The actual number of available IP addresses in the subnet only needs to be equal to the number of new VMs being deployed but this cannot be calculated by the current UI.
Fix: You can specify a subnet with at least as many IP addresses available as the number of VMs being added by not using the Marketplace UI, this can be done by specifying the subnet name in the "existingSubnetName" parameter when you redeploy an existing deployment or deploy using the underlying ARM template from GitHub.
