If you ask through the management interface, to remove a CPU from a partition, the HV will communicate with a daemon inside the partition that will then unplug the CPU via the right call. I don't really understand your objections to be honest. And I fail to see why it would be a layering violation to have the ability for the OS to indicate in what state it wishes to relinguish a CPU to the hypervisor, which more or less defines what is the expected latency for getting it back later on.
