NAME

       nova-compute - Server for the OpenStack Compute compute service.

SYNOPSIS

          nova-compute [<options>...]

DESCRIPTION

       nova-compute is a server daemon that serves the Nova Compute service, which is responsible
       for building a disk image, launching an instance via the underlying virtualization driver,
       responding  to  calls  to  check  the  instance's state, attaching persistent storage, and
       terminating the instance.

OPTIONS

       General options

       --config-dir DIR
              Path to a config directory to pull *.conf files from. This file set is  sorted,  so
              as  to provide a predictable parse order if individual options are over-ridden. The
              set is parsed after the file(s) specified  via  previous  --config-file,  arguments
              hence  over-ridden  options  in the directory take precedence.  This option must be
              set from the command-line.

       --config-file PATH
              Path to a config file to use. Multiple config files can be specified,  with  values
              in  later  files  taking precedence. Defaults to None. This option must be set from
              the command-line.

       --debug, -d
              Set the logging level to DEBUG instead of the default INFO level.

       --log-config-append PATH, --log-config PATH, --log_config PATH
              The name of a logging configuration file. This file is  appended  to  any  existing
              logging  configuration  files.   For details about logging configuration files, see
              the Python logging module documentation. Note that when logging configuration files
              are  used then all logging configuration is set in the configuration file and other
              logging configuration options are ignored (for example, log-date-format).

       --log-date-format DATE_FORMAT
              Defines the format string for %(asctime)s in log records.  Default:  None  .   This
              option is ignored if log_config_append is set.

       --log-dir LOG_DIR, --logdir LOG_DIR
              (Optional)  The  base  directory  used  for relative log_file paths. This option is
              ignored if log_config_append is set.

       --log-file PATH, --logfile PATH
              (Optional) Name of log file to send logging output  to.   If  no  default  is  set,
              logging  will  go  to  stderr  as  defined by use_stderr. This option is ignored if
              log_config_append is set.

       --nodebug
              The inverse of --debug.

       --nouse-journal
              The inverse of --use-journal.

       --nouse-json
              The inverse of --use-json.

       --nouse-syslog
              The inverse of --use-syslog.

       --nowatch-log-file
              The inverse of --watch-log-file.

       --syslog-log-facility SYSLOG_LOG_FACILITY
              Syslog facility to receive log lines. This option is ignored  if  log_config_append
              is set.

       --use-journal
              Enable  journald  for  logging. If running in a systemd environment you may wish to
              enable journal support.  Doing so  will  use  the  journal  native  protocol  which
              includes  structured metadata in addition to log messages.This option is ignored if
              log_config_append is set.

       --use-json
              Use JSON formatting for logging. This option is  ignored  if  log_config_append  is
              set.

       --use-syslog
              Use  syslog  for  logging. Existing syslog format is DEPRECATED and will be changed
              later to honor RFC5424.  This option is ignored if log_config_append is set.

       --version
              Show program's version number and exit

       --watch-log-file
              Uses logging handler designed to watch file system.  When  log  file  is  moved  or
              removed  this handler will open a new log file with specified path instantaneously.
              It makes sense only if log_file option is specified and  Linux  platform  is  used.
              This option is ignored if log_config_append is set.

       Debugger options

       --remote_debug-host REMOTE_DEBUG_HOST
              Debug host (IP or name) to connect to. This command line parameter is used when you
              want to connect to a nova service via a debugger running on a different host.  Note
              that  using  the  remote debug option changes how Nova uses the eventlet library to
              support async IO. This could result in failures that  do  not  occur  under  normal
              operation. Use at your own risk.

       --remote_debug-port REMOTE_DEBUG_PORT
              Debug  port  to  connect  to. This command line parameter allows you to specify the
              port you want to use to connect to  a  nova  service  via  a  debugger  running  on
              different  host.  Note that using the remote debug option changes how Nova uses the
              eventlet library to support async IO. This could result in  failures  that  do  not
              occur under normal operation. Use at your own risk.
