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.

the restart.
docs: Do not support non-socket activated modular daemons with systemd Due to the setup of the modular daemon service files the reverting to non-socket activated daemons could have never worked. The reason is that masking the socket files prevents starting the daemons since they require (as in Requires= rather than Wants= in the service file) the sockets. On top of that it creates issues with some libvirt-guests setups and needlessly increases our support matrix. Nothing prevents users to modify their setup in a way that will still work without socket activation, but supporting such setup only creates burden on our part. This technically reverts most of commit 59d30adacd1d except the change made to the libvirtd manpage since the monolithic daemon still supports traditional mode of starting even on systemd.

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

**Note**: The TCP socket uses plain unencrypted TCP connection and thus is
insecure and should not be used.
