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.

libvirtd - libvirtd management daemon
SYNOPSIS
libvirtd [ -dlv ] [ -f config_file ] [ -p pid_file ] [ -t timeout_seconds ]
libvirtd --version
DESCRIPTION
The libvirtd program is the server side daemon component of the libvirt virtualization management system.
This daemon runs on host servers and performs required management tasks for virtualized guests. This includes activities such as starting,
stopping and migrating guests between host servers, configuring and manipulating networking, and managing storage for use by guests.
The libvirt client libraries and utilities connect to this daemon to issue tasks and collect information about the configuration and
resources of the host system and guests.
By default, the libvirtd daemon listens for requests on a local Unix domain socket. Using the -l|--listen command line option, the
libvirtd daemon can be instructed to additionally listen on a TCP/IP socket. The TCP/IP socket to use is defined in the libvirtd
configuration file.
Restarting libvirtd does not impact running guests. Guests continue to operate and will be picked up automatically if their XML
configuration has been defined. Any guests whose XML configuration has not been defined will be lost from the configuration.
OPTIONS -d, --daemon
Run as a daemon & write PID file.
-f, --config FILE
Use this configuration file, overriding the default value.
-l, --listen
Listen for TCP/IP connections.
-p, --pid-file FILE
Use this name for the PID file, overriding the default value.
-t, --timeout SECONDS
Exit after timeout period (in seconds) expires.
-v, --verbose
Enable output of verbose messages.
--version
Display version information then exit.
SIGNALS
On receipt of SIGHUP libvirtd will reload its configuration.
FILES
@sysconfdir@/libvirtd.conf
The default configuration file used by libvirtd, unless overridden on the command line using the -f|--config option.
@localstatedir@/run/libvirt/libvirt-sock
@localstatedir@/run/libvirt/libvirt-sock-ro
The sockets libvirtd will use when run as root.
$HOME/.libvirt/libvirt-sock
The socket libvirtd will use when run as a non-root user.
@sysconfdir@/pki/CA/cacert.pem
The TLS Certificate Authority certificate libvirtd will use.
@sysconfdir@/pki/libvirt/servercert.pem
The TLS Server certificate libvirtd will use.
@sysconfdir@/pki/libvirt/private/serverkey.pem
The TLS Server private key libvirtd will use.
@remote_pid_file@
The PID file to use, unless overridden by the -p|--pid-file option.
EXAMPLES
To retrieve the version of libvirtd:
# libvirtd --version
libvirtd (libvirt) 0.8.2
#
To start libvirtd, instructing it to daemonize and create a PID file:
# libvirtd -d
# ls -la
-rw-r--r-- 1 root root 6 Jul 9 02:40
