| 19 | help |
| 20 | Say Y here to use the hypervisor-provided Virtual Machine Generation ID |
| 21 | to reseed the RNG when the VM is cloned. This is highly recommended if |
| 22 | you intend to do any rollback / cloning / snapshotting of VMs. |

| 31 | The Freescale hypervisor management driver provides several services |
| 32 | to drivers and applications related to the Freescale hypervisor: |
| 33 | |
| 34 | 1) An ioctl interface for querying and managing partitions. |
| 35 | |
| 36 | 2) A file interface to reading incoming doorbells. |
| 37 | |
| 38 | 3) An interrupt handler for shutting down the partition upon |
| 39 | receiving the shutdown doorbell from a manager partition. |
| 40 | |
| 41 | 4) A kernel interface for receiving callbacks when a managed |
| 42 | partition shuts down. |
