The SBS and SQL servers we restored to our newly created 2 node Hyper-V cluster were originally installed on HP hardware.
Once the P2V process using the native Windows Server Backup to restore to Hyper-V completed the restore process automatically rebooted the VMs.
One of the first things we noticed was that that vCPUs were running at a constant 100%. The Task Manager Processes tab showed a series of HP/CPQ services causing the problem.
So, we went in and disabled all of the services then shut them down.
Once we rebooted the VMs the HP services were no longer an issue.
