I had just installed two new Hyper-V hosts (non-clustered) and installed SC 2012 Virtual Machine Manager and was testing functionality. Whenever I tried to move a VM from one host to the other, I received error 2927 – A Hardware Management error has occurred trying to contact server LABHOST01.lab.local. Unknown error (0x8033811e). The recommended action was to check if WinRM is installed and running on the server.
After unsuccessfully trying to troubleshoot a WinRM issue, I came across a MS Fast Publish Article ID 2405062 – Transfers between the System Center Virtual Machine Manager server, the Library Server and the Virtualization Hosts may fail with error 12700, 2927, or 2912.
The issue turned out to be the default port (443 decimal) that BITS was using. To correct, in the registry of the VMM Server I went to HKLM\SOFTWARE\Microsoft\Microsoft System Center Virtual Machine Manager Server\Settings and changed the value for BITScpPort from 443 to 8500 (decimal) per the article after verifying this port was not being used and restarted the VMM Server Service. Afterwards I was then able to transfers VMs between hosts without any issues.
