6 | The balloon driver allows the Xen domain to request more memory from | |
7 | the system to expand the domain's memory allocation, or alternatively | |

15 | Scrub pages before returning them to the system for reuse by | |
16 | other domains. This makes sure that any confidential data | |
17 | is not accidentally visible to other domains. Is it more | |
18 | secure, but slightly less efficient. | |
19 | If in doubt, say yes. |
