Windows Azure Pack – Failed to Register Virtual Machine Cloud Provider
I was installing Windows Azure Pack to a different lab environment (having not had a problem on previous occasions) and everything was fine until connecting to Virtual Machine Manager. Every time I tried, I got the error “Failed to register virtual machine cloud provider”:
Clicking on ‘Details’ only gave “An error occurred while processing this request.” I did some troubleshooting, including following the great blog article from Microsoft Troubleshooting Windows Azure Pack, SPF & VMM, all of which didn’t point to the problem.
I went to the Event Viewer on the server running Windows Azure Pack (only an express installation in this lab) and navigated to ‘Applications and Services Logs > Microsoft > WindowAzurePack > MgmtSvc-AdminAPI > Operational‘ and there were several long errors in there. They were all slightly different in content, but all started the same way:
- Resource provider unexpected exception for proxy request with verb ‘GET’, operation name ‘Outgoing admin proxy call’
Sounds like a PowerShell issue…
Reading further into each error, I spotted the following:
- Invoking method GetSupportedQueryOptions of type Microsoft.SystemCenter.Foundation.Psws.Spf.SpfOperationManager failed. Cause of the problem: Windows PowerShell updated your execution policy successfully, but the setting is overridden by a policy defined at a more specific scope. Due to the override, your shell will retain its current effective execution policy of Unrestricted.
Having a look at the Execution Policy, it was indeed set to Unrestricted. I found in Group Policy that the setting ‘Turn on Script Execution’ was enabled. I removed this, ran a gpupdate and checked the Execution Policy again, which had now reverted to Restricted. I also ran update on the Service Provider Foundation server and check it was now set to Restricted.
Connecting to Virtual Machine Manager now worked as expected.
