SYNOPSIS
virtvzd
[OPTION]...
DESCRIPTION
The virtvzd
program is a server side daemon component of the libvirt virtualization management system.
It is one of a collection of modular daemons that replace functionality previously provided by the monolithic libvirtd
daemon.
This daemon runs on virtualization hosts to provide management for Virtuozzo virtual machines.
The virtvzd
daemon only listens for requests on a local Unix domain socket. Remote off-host access and backwards compatibility with legacy clients expecting libvirtd
is provided by the virtproxy
daemon.
Restarting virtvzd
does not interrupt running guests. Guests continue to operate and changes in their state will generally be picked up automatically during startup. None the less it is recommended to avoid restarting with running guests whenever practical.
SYSTEM SOCKET ACTIVATION
The virtvzd
daemon is capable of starting in two modes.
In the traditional mode, it will create and listen on UNIX sockets itself.
In socket activation mode, it will rely on systemd to create and listen on the UNIX sockets and pass them as pre-opened file descriptors. In this mode most of the socket related config options in /etc/libvirt/virtvzd.conf
will no longer have any effect.
Socket activation mode is generally the default when running on a host OS that uses systemd. To revert to the traditional mode, all the socket unit files must be masked:
$ systemctl mask virtvzd.socket virtvzd-ro.socket \
virtvzd-admin.socket
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.
-p
, --pid-file *FILE*
Use this name for the PID file, overriding the default value.
-t
, --timeout *SECONDS*
Exit after timeout period (in seconds), provided there are neither any client connections nor any running domains.
-v
, --verbose
Enable output of verbose messages.
--version
Display version information then exit.
SIGNALS
On receipt of SIGHUP
virtvzd
will reload its configuration.
FILES
When run as root
@SYSCONFDIR@/libvirt/virtvzd.conf
The default configuration file used by virtvzd
, unless overridden on the command line using the -f
| --config
option.
@RUNSTATEDIR@/libvirt/virtvzd-sock
@RUNSTATEDIR@/libvirt/virtvzd-sock-ro
@RUNSTATEDIR@/libvirt/virtvzd-admin-sock
The sockets virtvzd
will use.
The TLS Server private key virtvzd
will use.
@RUNSTATEDIR@/virtvzd.pid
The PID file to use, unless overridden by the -p
| --pid-file
option.
When run as non-root
$XDG_CONFIG_HOME/libvirt/virtvzd.conf
The default configuration file used by virtvzd
, unless overridden on the command line using the -f
|--config
option.
$XDG_RUNTIME_DIR/libvirt/virtvzd-sock
$XDG_RUNTIME_DIR/libvirt/virtvzd-admin-sock
The sockets virtvzd
will use.
$XDG_RUNTIME_DIR/libvirt/virtvzd.pid
The PID file to use, unless overridden by the -p
|--pid-file
option.
If $XDG_CONFIG_HOME
is not set in your environment, virtvzd
will use $HOME/.config
If $XDG_RUNTIME_DIR
is not set in your environment, virtvzd
will use $HOME/.cache
EXAMPLES
To retrieve the version of virtvzd
:
# virtvzd --version
virtvzd (libvirt) @VERSION@
To start virtvzd
, instructing it to daemonize and create a PID file:
# virtvzd -d
# ls -la @RUNSTATEDIR@/virtvzd.pid
-rw-r--r-- 1 root root 6 Jul 9 02:40 @RUNSTATEDIR@/virtvzd.pid
