BMD(8) System Manager's Manual BMD(8) NAME bmd -- bhyve management daemon SYNOPSIS bmd [-F] [-f config_file] [-P pid_file] [-p plugin_directory] [-m unix_domain_socket_permission] [-v] DESCRIPTION The bmd utility spawns bhyve processes according to the configuration file, and waits for them to terminate. If a bhyve process terminates with exit code 0 (rebooted), bmd spawns the bhyve process again. The bmd receives control commands from bmdctl(8) to manage bhyve processes via unix domain socket. See bmdctl(8) for detail. OPTIONS -F Run in foreground. -f config_file Specify the pathname of an alternate configuration file. The de- fault is /usr/local/etc/bmd.conf. -P pid_file Specify an alternative file in which to store the process ID. The default is /var/run/bmd.pid. -p plugin_directory Specify the directory path of an alternate plugin store. The de- fault is /usr/local/libexec/bmd. -m unix_domain_socket_permission Specify the unix domain socket permission in octal number. The de- fault is 0660. Please note that the unix domain socket path cannot be changed in command line options. See bmd.conf(5) to change the path. -v Show version number. The bmd waits for control commands from bmdctl(8) via unix domain socket. When bmd receives a boot request from bmdctl(8), bmd reloads the configura- tion file to check updates for boot target. If any updates are found, the bmd adopts the updated configuration. LOGGING bmd writes log messages to LOG_DAEMON facility. Usually it is written in the '/var/log/daemon.log' file by the syslogd(8). You can see error mes- sages of BMD and informational messages such as starting a VM or stopping a VM with or without an error. SIGNAL HANDLING bmd deals with the following signals: SIGTERM Send SIGTERM to all bhyve processes and wait for them to termi- nate, then quit the daemon. SIGHUP Reload the configuration file. PLUGINS bmd loads plugins on start up. Plugins extend the functionality of bmd. And also add configuration parameters for extended functionality if neces- sary.
