#*******************************************************************************
# Daemon configuration attributes
#-------------------------------------------------------------------------------
#  MESSAGE_SIZE: Buffer size in bytes for XML-RPC responses.
#
#  XMLRPC_TIMEOUT: Seconds to timeout XML-RPC calls to oned
#
#  ONE_XMLRPC: URL to connect to the OpenNebula daemon (oned)
#
#  SCHED_INTERVAL: Seconds between two scheduling actions
#
#  MAX_VM: Maximum number of Virtual Machines scheduled in each scheduling
#          action. Use 0 to schedule all pending VMs each time.
#
#  MAX_DISPATCH: Maximum number of Virtual Machines actually dispatched to a
#                host in each scheduling action
#
#  MAX_HOST: Maximum number of Virtual Machines dispatched to a given host in
#            each scheduling action
#
#  LIVE_RESCHEDS: Perform live (1) or cold migrations (0) when rescheduling a VM
#
#  DEFAULT_SCHED: Definition of the default scheduling algorithm
#    - policy:
#      0 = Packing. Heuristic that minimizes the number of hosts in use by
#          packing the VMs in the hosts to reduce VM fragmentation
#      1 = Striping. Heuristic that tries to maximize resources available for
#          the VMs by spreading the VMs in the hosts
#      2 = Load-aware. Heuristic that tries to maximize resources available for
#          the VMs by using those nodes with less load
#      3 = Custom.
#    - rank: Custom arithmetic expression to rank suitable hosts based in their
#            attributes
#      4 = Fixed. Hosts will be ranked according to the PRIORITY attribute found
#          in the Host or Cluster template.
#
#  DEFAULT_DS_SCHED: Definition of the default storage scheduling algorithm
#    - policy:
#      0 = Packing. Tries to optimize storage usage by selecting the DS with
#          less free space
#      1 = Striping. Tries to optimize I/O by distributing the VMs across
#          datastores.
#      2 = Custom.
#    - rank: Custom arithmetic exprission to rank suitable datastores based on
#          their attributes
#      3 = Fixed. Datastores will be ranked according to the PRIORITY attribute
#          found in the Datastore template.
#
#
#  LOG: Configuration for the logging system
#    - system: defines the logging system:
#          file      to log in the sched.log file
#          syslog    to use the syslog facilities
#    - debug_level:
#           0 = ERROR
#           1 = WARNING
#           2 = INFO
#           3 = DEBUG   Includes general scheduling information (default)
#           4 = DDEBUG  Includes time taken for each step
#           5 = DDDEBUG Includes detailed information about the scheduling
#                       decision, such as VM requirements, Host ranking for
#                       each VM, etc. This will impact the performance
#
#  MEMORY_SYSTEM_DS_SCALE: This factor scales the VM usage of the system DS with
#  the memory size. This factor can be use to make the scheduler consider the
#  overhead of checkpoint files:
#       system_ds_usage = system_ds_usage + memory_system_ds_scale * memory
