"Microsoft.Rest.Azure.CloudException: 'Long running operation failed with status 'Failed'. Additional Info:'OS Provisioning for VM 'Test-3' did not finish in the allotted time. However, the VM guest agent was detected running. This suggests the guest OS has not been properly prepared to be used as a VM image (with CreateOption=FromImage). To resolve this issue, either use the VHD as is with CreateOption=Attach or prepare it properly for use as an image:
