NAME
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.
