NAME
virtlockd - libvirt lock management daemon SYNOPSIS
virtlockd [ -dv ] [ -f config_file ] [ -p pid_file ] virtlockd --version DESCRIPTION
The virtlockd program is a server side daemon component of the libvirt virtualization management system that is used to manage locks held against virtual machine resources, such as their disks. This daemon is not used directly by libvirt client applications, rather it is called on their behalf by libvirtd. By maintaining the locks in a standalone daemon, the main libvirtd daemon can be restarted without risk of losing locks. The virtlockd daemon has the ability to re-exec() itself upon receiving SIGUSR1, to allow live upgrades without downtime. The virtlockd daemon listens for requests on a local Unix domain socket. OPTIONS
-h, --help Display command line help usage then exit. -d, --daemon Run as a daemon and write PID file. -f, --config FILE Use this configuration file, overriding the default value. -p, --pid-file FILE Use this name for the PID file, overriding the default value. -v, --verbose Enable output of verbose messages. -V, --version Display version information then exit. SIGNALS
On receipt of SIGUSR1 virtlockd will re-exec() its binary, while maintaining all current locks and clients. This allows for live upgrades of the virtlockd service. FILES
When run as root. SYSCONFDIR/virtlockd.conf The default configuration file used by virtlockd, unless overridden on the command line using the -f|--config option. LOCALSTATEDIR/run/libvirt/virtlockd-sock The sockets libvirtd will use. LOCALSTATEDIR/run/virtlockd.pid The PID file to use, unless overridden by the -p|--pid-file option. When run as non-root. $XDG_CONFIG_HOME/virtlockd.conf The default configuration file used by libvirtd, unless overridden on the command line using the -f|--config option. $XDG_RUNTIME_DIR/libvirt/virtlockd-sock The socket libvirtd will use. $XDG_RUNTIME_DIR/libvirt/virtlockd.pid The PID file to use, unless overridden by the -p|--pid-file option. If $XDG_CONFIG_HOME is not set in your environment, libvirtd will use $HOME/.config If $XDG_RUNTIME_DIR is not set in your environment, libvirtd will use $HOME/.cache EXAMPLES
To retrieve the version of virtlockd: # virtlockd --version virtlockd (libvirt) 1.1.1 # To start virtlockd, instructing it to daemonize and create a PID file: # virtlockd -d # ls -la LOCALSTATEDIR/run/virtlockd.pid -rw-r--r-- 1 root root 6 Jul 9 02:40 LOCALSTATEDIR/run/virtlockd.pid # BUGS

LIBVIRTMIB_SUBAGENT(1)					      Virtualization Support					    LIBVIRTMIB_SUBAGENT(1)

NAME
libvirtMib_subagent - SNMP subagent for libvirt SYNOPSIS
libvirtMib_subagent [OPTIONS] [LISTENING ADDRESSES] DESCRIPTION
The libvirtMib_subagent provides SNMP functionality for libvirt. Therefore it is now possible to gather and set domain status over SNMP from one place. This allows to create views of entire platforms end to end. It communicates with SNMP agent over AgentX protocol (RFC 2741) and extends agent's set of infomation provided. Therefore, we need a running SNMP agent. This behaviour can be avoided using -M option. The libvirtMib_subagent understands these OPTIONS: -f Don't fork. Run in foreground. -D[token[,...]] Turn on debugging output for the given TOKEN(s). Without any tokens specified, it defaults to printing all the tokens (which is equivalent to the keyword '"ALL"'). You might want to try ALL for extremely verbose output. Note: You can't put a space between the -D and the tokens. -H Display a list of configuration file directives understood by the agent and then exit. -M Run as a normal SNMP Agent instead of an AgentX sub-agent. -xADDRESS Connect to master agent at ADDRESS (default "/var/agentx/master"). The address can either be a Unix domain socket path, or the address of a network interface. The format is the same as the format of listening addresses described below. -L Do not open a log file; print all messages to stderr. The last optional LISTENING ADDRESSES specify on which addresses should subagent running in normal SNMP Agent mode listen for incoming requests. See snmpd for further information. BUGS
Report any bugs discovered to the libvirt community via the mailing list "http://libvirt.org/contact.html" or bug tracker "http://libvirt.org/bugs.html". Alternatively report bugs to your software distributor / vendor. AUTHORS
