      Description of problem:
      A VM with enabled CPU pinning will pin it's CPUs to (likely) the wrong CPU set after a migration.

      When the VM is started it is getting set (A) of cores to pin to and will do so.
      After migration the VM will get a different set (B), the pinning would need to be re-done, but this is not the case today.

      Version-Release number of selected component (if applicable):
      2.6

      How reproducible:
      always

      Steps to Reproduce:
      1. VM with pinning enabled
      2. Live migrated
      3. Check if VM is pinend to the new CPU set

      Actual results:
      It is not pinned to the new CPU set, it is pinned to the old

      Expected results:
      It is pinend to the new CPU set
