|  | 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. |
