What: /sys/devices/system/xen_memory/xen_memory0/max_retry_count
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.
What: /sys/devices/system/xen_memory/xen_memory0/max_schedule_delay
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.
What: /sys/devices/system/xen_memory/xen_memory0/retry_count
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).
