Spell out that TCP and TLS needs virtproxyd as 'off-host' might mean that also ssh transport requires it. Also fix the name of the 'virtproxyd' daemon. Signed-off-by: Peter Krempa <pkrempa@redhat.com> Reviewed-by: Michal Privoznik <mprivozn@redhat.com>

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 access via TLS/TCP and backwards
compatibility with legacy clients expecting libvirtd is
provided by the virtproxyd 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.
DAEMON STARTUP MODES
The virtxend 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 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.
Traditional service mode
On hosts without systemd, it will create and listen on UNIX sockets itself.
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 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
