The maximum number of times the balloon driver will

attempt to increase the balloon before giving up. See

also 'retry_count' below.

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.

|

|
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
