#
# [*update_resources_interval*]
# (optional) Interval for updating compute resources.
# This option specifies how often the update_available_resources periodic
# task should run. A number less than 0 means to disable the task completely
# Leaving this at the default of 0 will cause this to run at the default
# periodic interval. Setting it to any positive value will cause it to run
# at approximately that number of seconds.

# server status from resized to active. Setting this option to a time
# period (in seconds) will automatically confirm the resize if the
# server is in resized state longer than that time.
# Defaults to $facts['os_service_default']
#
# [*shutdown_timeout*]
# (optional) Total time to wait in seconds for an instance to perform a clean
# shutdown. It determines the overall period (in seconds) a VM is allowed to
# perform a clean shutdown. While performing stop, rescue and shelve, rebuild
# operations, configuring this option gives the VM a chance to perform a
# controlled shutdown before the instance is powered off.
# Defaults to $facts['os_service_default']

# and attach volume.
# Defaults to $facts['os_service_default']
