"No virtual network found" error when you configure Azure deployment settings
This article explains how to resolve the "no virtual network found" error that occurs when you configure Azure deployment settings in HPC Pack Cluster Manager.
Symptoms
You deploy an HPC Pack cluster purely in Azure or in a Hybrid (burst to Azure IaaS nodes) environment. After you manually input the service principal application ID in the Azure Deployment Settings section of the Azure Service Principal webpage, you receive the following error message:
No virtual network found in this Azure subscription, select another subscription.
Cause
This error might occur if you use Azure Service Principal instead of Managed Identity to enable the head node to manage the Azure IaaS compute nodes.
If you use a service principal, and if the Contributor role for the subscription isn't assigned, you have to manually input the application ID in the GUI. This error occurs because the subscription-level Contributor role isn't assigned to the service principal. (For example, you might have configured the service principal without assigning the Contributor role because you want to limit access to only certain resource groups.)
In this situation, the service principal is listed on the HPC Pack deployment wizard menu. (You don't have to manually input the application ID in the GUI.)
Solution 1: If you don't want to limit permissions to specific resource groups
Unless you want to limit permissions to specific resource groups, you must assign the Contributor role for the service principal. See Assign Azure roles using the portal and Steps to assign an Azure role.
Solution 2: If you want to limit permissions to specific resource groups
If you want to limit permissions to specific resource groups, you must grant the following roles before you manually input the service principal application ID.
| Role | Description |
|---|---|
| Virtual Machine Contributor | For the resource groups in which you want to create compute nodes |
| Network Contributor | For the virtual network in which the Azure virtual machine (VM) compute nodes join |
| Key Vault Contributor | For the Azure Key Vault in which the Azure Key Vault certificate was created |
