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.
OPTIONS¶
- -h, --help
- Display command line help usage then exit.
- -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.

- 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
