LIBVIRTD(8) Virtualization Support LIBVIRTD(8)NAMElibvirtd - libvirtd management daemon
SYNOPSISlibvirtd [ -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) elapse with no client
connections or registered resources. Be aware that resources such
as autostart networks will result in never reaching the timeout,
even when there are no client connections.
-v, --verbose
Enable output of verbose messages.
--version
Display version information then exit.
SIGNALS
On receipt of SIGHUP libvirtd will reload its configuration.
FILES
When run as root.
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.

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.
LOCALSTATEDIR/run/libvirtd.pid
The PID file to use, unless overridden by the -p|--pid-file option.
When run as non-root.
$XDG_CONFIG_HOME/libvirtd.conf
The default configuration file used by libvirtd, unless overridden
on the command line using the -f|--config option.
$XDG_RUNTIME_DIR/libvirt/libvirt-sock
The socket libvirtd will use.
$HOME/.pki/libvirt/cacert.pem

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
