The default conf files, for example libvirtd.conf, virtlockd.conf, and virtlogd.conf, should be located under the directory "/etc/libvirt" when root as root, rather than "/etc". When run as non-root, the configuration files should be located under "$XDG_CONFIG_HOME/libvirt/", rather than "XDG_CONFIG_HOME".

=head1 NAME

|
|
virtlogd - libvirt log management daemon
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<virtlogd> [I<OPTION>]...
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The B<virtlogd> program is a server side daemon component of the libvirt
|
|
virtualization management system that is used to manage logs from virtual
|
|
machine consoles.
|
|
|
|
This daemon is not used directly by libvirt client applications, rather it
|
|
is called on their behalf by B<libvirtd>. By maintaining the logs in a
|
|
standalone daemon, the main libvirtd daemon can be restarted without risk
|
|
of losing logs. The B<virtlogd> daemon has the ability to re-exec()
|
|
itself upon receiving SIGUSR1, to allow live upgrades without downtime.
|
|
|
|
The virtlogd daemon listens for requests on a local Unix domain socket.

|
|
=item B<-h, --help>
|
|
|
|
Display command line help usage then exit.
|
|
|
|
=item B<-d, --daemon>

|
|
no active console log.
|
|
|
|
=item B<-p, --pid-file> I<FILE>
|

|
=head1 SIGNALS
|
|
|
|
On receipt of B<SIGUSR1> virtlogd will re-exec() its binary, while
|
|
maintaining all current logs and clients. This allows for live
|
|
upgrades of the virtlogd service.
