NAME

6       virtnwfilterd - libvirt network filter management daemon
7

SYNOPSIS

9       virtnwfilterd [OPTION]...
10

DESCRIPTION

12       The virtnwfilterd program is a server side daemon component of the lib‐
13       virt virtualization management system.
14
15       It is one of a collection of modular daemons that replace functionality
16       previously provided by the monolithic libvirtd daemon.
17
18       This daemon runs on virtualization hosts to provide management for net‐
19       work filters.
20
21       The virtnwfilterd daemon only listens for requests on a local Unix  do‐
22       main socket. Remote access via TLS/TCP and backwards compatibility with
23       legacy clients expecting libvirtd is provided by the virtproxyd daemon.
24
25       Restarting virtnwfilterd does not interrupt running guests. Guests con‐
26       tinue to operate and changes in their state will generally be picked up
27       automatically during startup. None the less it is recommended to  avoid
28       restarting with running guests whenever practical.
29

DAEMON STARTUP MODES

31       The virtnwfilterd daemon is capable of starting in two modes.
32
33   Socket activation mode
34       On  hosts  with  systemd it is started in socket activation mode and it
35       will rely on systemd to create and listen on the UNIX sockets and  pass
36       them  as  pre-opened  file descriptors. In this mode most of the socket
37       related  config  options  in  /etc/libvirt/virtnwfilterd.conf  will  no
38       longer have any effect.
39
40   Traditional service mode
41       On hosts without systemd, it will create and listen on UNIX sockets it‐
42       self.
43

OPTIONS

45       -h, --help
46
47       Display command line help usage then exit.
48
49       -d, --daemon
50
51       Run as a daemon & write PID file.
52
53       -f, --config *FILE*
54
55       Use this configuration file, overriding the default value.
56
57       -p, --pid-file *FILE*
58
59       Use this name for the PID file, overriding the default value.
60
61       -t, --timeout *SECONDS*
62
63       Exit after timeout period (in seconds), provided there  are  no  client
64       connections.
65
66       -v, --verbose
67
68       Enable output of verbose messages.

87
88/run/libvirt/virtnwfilterd-admin-sock
89
90       The sockets virtnwfilterd will use.
91
92       The TLS Server private key virtnwfilterd will use.
93
94/run/virtnwfilterd.pid
95
96       The PID file to use, unless overridden by the -p | --pid-file option.
97
98   When run as non-root
99$XDG_CONFIG_HOME/libvirt/virtnwfilterd.conf
100
101       The default configuration file used by virtnwfilterd, unless overridden
102       on the command line using the -f``|--config`` option.
103
104$XDG_RUNTIME_DIR/libvirt/virtnwfilterd-sock
105
106$XDG_RUNTIME_DIR/libvirt/virtnwfilterd-admin-sock
107
108       The sockets virtnwfilterd will use.
109
110$XDG_RUNTIME_DIR/libvirt/virtnwfilterd.pid
111
112       The PID file to use, unless overridden by the -p``|--pid-file`` option.
113
114       If  $XDG_CONFIG_HOME is not set in your environment, virtnwfilterd will
115       use $HOME/.config
116
117       If $XDG_RUNTIME_DIR is not set in your environment, virtnwfilterd  will
118       use $HOME/.cache

EXAMPLES

121       To retrieve the version of virtnwfilterd:
122
123          # virtnwfilterd --version
124          virtnwfilterd (libvirt) 9.7.0
125
126       To  start  virtnwfilterd,  instructing it to daemonize and create a PID
127       file:
128
129          # virtnwfilterd -d
130          # ls -la /run/virtnwfilterd.pid
131          -rw-r--r-- 1 root root 6 Jul  9 02:40 /run/virtnwfilterd.pid
