This is similar to my earlier commit which documented lxc.conf location. Just like LXC, the libxl driver has only the system connection and thus only few places need changing. Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Andrea Bolognani <abologna@redhat.com>

libvirt Xen management daemon

SYNOPSIS
virtxend [OPTION]...
DESCRIPTION
The virtxend 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 Xen virtual machines.
The virtxend 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 virtxend 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 virtxend 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/virtxend.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 virtxend.socket virtxend-ro.socket \
virtxend-admin.socketOPTIONS
-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 virtxend will reload its configuration.
FILES
The virtxend program must be ran as root. Trying to start the program under a different user results in error.
@SYSCONFDIR@/libvirt/virtxend.conf
The default configuration file used by virtxend, unless overridden on the command line using the -f | --config option.
In addition to the default configuration file, virtxend reads configuration for the libxl driver from:
@SYSCONFDIR@/libvirt/libxl.conf
This file contains various knobs and default values for virtual machines created within libxl driver, and offers a way to override the built in defaults, Location of this file can't be overridden by any command line switch.
@RUNSTATEDIR@/libvirt/virtxend-sock@RUNSTATEDIR@/libvirt/virtxend-sock-ro@RUNSTATEDIR@/libvirt/virtxend-admin-sock
The sockets virtxend will use.
The TLS Server private key virtxend will use.
@RUNSTATEDIR@/virtxend.pid
The PID file to use, unless overridden by the -p | --pid-file option.
EXAMPLES
To retrieve the version of virtxend:
# virtxend --version
virtxend (libvirt) @VERSION@To start virtxend, instructing it to daemonize and create a PID file:
# virtxend -d
# ls -la @RUNSTATEDIR@/virtxend.pid
-rw-r--r-- 1 root root 6 Jul 9 02:40 @RUNSTATEDIR@/virtxend.pidBUGS
