Hi,
It seems that the deployment process of the virtual machine on Hyper-V is stuck at the "Creating virtual machine" stage.
Have you checked the event log for Hyper-V and VMM?
This issue can occur when deploying services from the service templates that are configured to install Windows Server Roles and Features that require a double reboot. The VMM job fails with some or all of the following errors: Error (22042) and Error (22011). To resolve this issue, you can restart the deployment by retrying the job. If the issue persists, check error messages and retry the operation if needed.
