=encoding utf-8 =head1 NAME libvirtd - libvirtd management daemon =head1 SYNOPSIS B [ -dlv ] [ -f config_file ] [ -p pid_file ] [ -t timeout_seconds ] B --version =head1 DESCRIPTION The B 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 B<-l>|B<--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. =head1 OPTIONS =over =item B<-d, --daemon> Run as a daemon & write PID file. =item B<-f, --config> I Use this configuration file, overriding the default value. =item B<-l, --listen> Listen for TCP/IP connections. =item B<-p, --pid-file> I Use this name for the PID file, overriding the default value. =item B<-t, --timeout> I Exit after timeout period (in seconds) expires. =item B<-v, --verbose> Enable output of verbose messages. =item B< --version> Display version information then exit. =back =head1 SIGNALS On receipt of B libvirtd will reload its configuration. =head1 FILES =over =item F<@sysconfdir@/libvirtd.conf> The default configuration file used by libvirtd, unless overridden on the command line using the B<-f>|B<--config> option. =item F<@localstatedir@/run/libvirt/libvirt-sock> =item F<@localstatedir@/run/libvirt/libvirt-sock-ro> The sockets libvirtd will use when B. =item F<$HOME/.libvirt/libvirt-sock> The socket libvirtd will use when run as a B user. =item F<@sysconfdir@/pki/CA/cacert.pem> The TLS B certificate libvirtd will use. =item F<@sysconfdir@/pki/libvirt/servercert.pem> The TLS B certificate libvirtd will use. =item F<@sysconfdir@/pki/libvirt/private/serverkey.pem> The TLS B private key libvirtd will use. =item F<@remote_pid_file@> The PID file to use, unless overridden by the B<-p>|B<--pid-file> option. =back =head1 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 @remote_pid_file@ -rw-r--r-- 1 root root 6 Jul 9 02:40 @remote_pid_file@ # =head1 BUGS Please report all bugs you discover.
