As defined in: http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html This offers a number of advantages: * Allows sharing a home directory between different machines, or sessions (eg. using NFS) * Cleanly separates cache, runtime (eg. sockets), or app data from user settings * Supports performing smart or selective migration of settings between different OS versions * Supports reseting settings without breaking things * Makes it possible to clear cache data to make room when the disk is filling up * Allows us to write a robust and efficient backup solution * Allows an admin flexibility to change where data and settings are stored * Dramatically reduces the complexity and incoherence of the system for administrators

libvirtd - libvirtd management daemon
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<libvirtd> [ -dlv ] [ -f config_file ] [ -p pid_file ] [ -t timeout_seconds ]
|
|
|
|
B<libvirtd> --version
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The B<libvirtd> program is the server side daemon component of the libvirt
|
|
virtualization management system.
|
|
|
|
This daemon runs on host servers and performs required management tasks for
|
|
virtualized guests. This includes activities such as starting, stopping
|
|
and migrating guests between host servers, configuring and manipulating
|
|
networking, and managing storage for use by guests.
|
|
|
|
The libvirt client libraries and utilities connect to this daemon to issue
|
|
tasks and collect information about the configuration and resources of the host
|
|
system and guests.
|
|
|
|
By default, the libvirtd daemon listens for requests on a local Unix domain
|
|
socket. Using the B<-l>|B<--listen> command line option, the libvirtd daemon
|
|
can be instructed to additionally listen on a TCP/IP socket. The TCP/IP socket
|
|
to use is defined in the libvirtd configuration file.
|
|
|
|
Restarting libvirtd does not impact running guests. Guests continue to operate
|
|
and will be picked up automatically if their XML configuration has been
|
|
defined. Any guests whose XML configuration has not been defined will be lost
|
|
from the configuration.
