| Date: May 2011 |
| KernelVersion: 2.6.39 |
| Contact: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> |
| Description: |
| The maximum number of times the balloon driver will |
| attempt to increase the balloon before giving up. See |
| also 'retry_count' below. |
| A value of zero means retry forever and is the default one. |

| Date: May 2011 |
| KernelVersion: 2.6.39 |
| Contact: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> |
| Description: |
| The limit that 'schedule_delay' (see below) will be |
| increased to. The default value is 32 seconds. |

| Date: May 2011 |
| KernelVersion: 2.6.39 |
| Contact: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> |
| Description: |
| The current number of times that the balloon driver |
| has attempted to increase the size of the balloon. |
| The default value is one. With max_retry_count being |
| zero (unlimited), this means that the driver will attempt |
| to retry with a 'schedule_delay' delay. |

| Date: May 2011 |
| KernelVersion: 2.6.39 |
| Contact: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> |
| Description: |
| The time (in seconds) to wait between attempts to |
| increase the balloon. Each time the balloon cannot be |
| increased, 'schedule_delay' is increased (until |
| 'max_schedule_delay' is reached at which point it |
| will use the max value). |
