SYNOPSIS
|
|
========
|
|
|
|
``virtproxyd`` [*OPTION*]...
|
|
|
|
|
|
DESCRIPTION
|
|
===========
|
|
|
|
The ``virtproxyd`` 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 and
|
|
|
|
* Listens on a UNIX socket to provide backwards compatibility for clients
|
|
that previously connected to the ``libvirtd`` socket.
|
|
|
|
* Optionally listens on TCP ports for connections from off-node clients
|
|
|
|
Upon receiving RPC messages from a client ``virtproxyd`` will transparently
|
|
forward them on to the appropriate modular daemon, and similarly relay back
|
|
any asynchronous events.
|
|
|
|
By default, the ``virtproxyd`` daemon listens for requests on a local Unix
|
|
domain socket with the same path previously used by ``libvirtd``. The
|
|
configuration file can be used to instruct it to also listen on TCP socket(s).
|
|
Systemd socket activation is also supported to allow it to receive pre-opened
|
|
listener sockets on startup.
|
|
|
|
Since ``virtproxyd`` merely forwards RPC messages, it has no important state,
|
|
and can be restarted at any time. Clients should expect to reconnect after
|
|
the restart.
|
|
|
|
|
|
DAEMON STARTUP MODES
|
|
====================
|
|
|
|
The ``virtproxyd`` daemon is capable of starting in two modes.
|
|
|
|
|
|
Socket activation mode
|
|
----------------------
|
|
|
|
On hosts with systemd it is started in socket activation mode and it will rely
|
|
on systemd to create and listen on the UNIX, and optionally TCP/IP, sockets and
|
|
pass them as pre-opened file descriptors. In this mode most of the socket
|
|
related config options in ``/etc/libvirt/virtproxyd.conf`` will no longer have
|
|
any effect. To enable TCP or TLS sockets use either
|
|
|
|
::
|
|
|
|
$ systemctl start virtproxyd-tls.socket
|
|
|
|
Or
|
|
|
|
::
|
|
|
|
$ systemctl start virtproxyd-tcp.socket
|
|
|
|
**Note**: The TCP socket uses plain unencrypted TCP connection and thus is
|
|
insecure and should not be used.
|
|
|
|
|
|
Traditional service mode
|
|
------------------------
|
|
|
|
On hosts without systemd, it will create and listen on UNIX sockets itself.
|
|
It will also listen on TCP/IP socket(s), according to the ``listen_tcp``
|
|
and ``listen_tls`` options in ``/etc/libvirt/virtproxyd.conf``
|
|
|
|
|
|
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 no client
|
|
connections.
|
|
|
|
``-v``, ``--verbose``
|
|
|
|
Enable output of verbose messages.
|
|
|
|
``--version``
|
|
|
|

|
|
|
|
|
|
SIGNALS
|
|
=======
|
|
|
|
On receipt of ``SIGHUP`` ``virtproxyd`` will reload its configuration.
