   4 Contact:        Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
   5 Description:
   6                 The maximum number of times the balloon driver will
   7                 attempt to increase the balloon before giving up.  See
   8                 also 'retry_count' below.
   9                 A value of zero means retry forever and is the default one.

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

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

  33 Contact:        Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
  34 Description:
  35                 The time (in seconds) to wait between attempts to
  36                 increase the balloon.  Each time the balloon cannot be
  37                 increased, 'schedule_delay' is increased (until
  38                 'max_schedule_delay' is reached at which point it
  39                 will use the max value).
