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.

Description:
  The limit that 'schedule_delay' (see below) will be

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.

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).
