NAME

6       virtinterfaced - libvirt host network interface management daemon
7

SYNOPSIS

9       virtinterfaced [OPTION]...
10

DESCRIPTION

12       The  virtinterfaced  program  is  a server side daemon component of the
13       libvirt 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 host
19       network interfaces.
20
21       The virtinterfaced daemon only listens for requests on a local Unix do‐
22       main  socket.  Remote  off-host access and backwards compatibility with
23       legacy clients expecting libvirtd is provided by the virtproxy daemon.
24
25       Restarting virtinterfaced does not  interrupt  running  guests.  Guests
26       continue to operate and changes in their state will generally be picked
27       up automatically during startup. None the less  it  is  recommended  to
28       avoid restarting with running guests whenever practical.
29

SYSTEM SOCKET ACTIVATION

31       The virtinterfaced daemon is capable of starting in two modes.
32
33       In  the traditional mode, it will create and listen on UNIX sockets it‐
34       self.
35
36       In socket activation mode, it will rely on systemd to create and listen
37       on  the  UNIX  sockets and pass them as pre-opened file descriptors. In
38       this mode most of  the  socket  related  config  options  in  /etc/lib‐
39       virt/virtinterfaced.conf will no longer have any effect.
40
41       Socket  activation mode is generally the default when running on a host
42       OS that uses systemd. To revert to the traditional mode, all the socket
43       unit files must be masked:
44
45          $ systemctl mask virtinterfaced.socket virtinterfaced-ro.socket \
46             virtinterfaced-admin.socket
47

OPTIONS

49       -h, --help
50
51       Display command line help usage then exit.
52
53       -d, --daemon
54
55       Run as a daemon & write PID file.
56
57       -f, --config *FILE*
58
59       Use this configuration file, overriding the default value.
60
61       -p, --pid-file *FILE*
62
63       Use this name for the PID file, overriding the default value.
64
65       -t, --timeout *SECONDS*
66
67       Exit  after timeout period (in seconds), provided there are neither any
68       client connections nor any running domains.
69
70       -v, --verbose
71
72       Enable output of verbose messages.
73
74       --version
75
76       Display version information then exit.
77

SIGNALS

79       On receipt of SIGHUP virtinterfaced will reload its configuration.
80

FILES

82   When run as root
83/etc/libvirt/virtinterfaced.conf
84
85       The default configuration file used by virtinterfaced, unless  overrid‐
86       den on the command line using the -f | --config option.
87
88/run/libvirt/virtinterfaced-sock
89
90/run/libvirt/virtinterfaced-sock-ro
91
92/run/libvirt/virtinterfaced-admin-sock
93
94       The sockets virtinterfaced will use.
95
96       The TLS Server private key virtinterfaced will use.
97
98/run/virtinterfaced.pid
99
100       The PID file to use, unless overridden by the -p | --pid-file option.
101
102   When run as non-root
103$XDG_CONFIG_HOME/libvirt/virtinterfaced.conf
104
105       The  default configuration file used by virtinterfaced, unless overrid‐
106       den on the command line using the -f``|--config`` option.
107
108$XDG_RUNTIME_DIR/libvirt/virtinterfaced-sock
109
110$XDG_RUNTIME_DIR/libvirt/virtinterfaced-admin-sock
111
112       The sockets virtinterfaced will use.
113
114$XDG_RUNTIME_DIR/libvirt/virtinterfaced.pid
115
116       The PID file to use, unless overridden by the -p``|--pid-file`` option.
117
118       If $XDG_CONFIG_HOME is not set in your environment, virtinterfaced will
119       use $HOME/.config
120
121       If $XDG_RUNTIME_DIR is not set in your environment, virtinterfaced will
122       use $HOME/.cache
123

EXAMPLES

125       To retrieve the version of virtinterfaced:
126
127          # virtinterfaced --version
128          virtinterfaced (libvirt) 7.6.0
129
130       To start virtinterfaced, instructing it to daemonize and create  a  PID
131       file:
132
133          # virtinterfaced -d
134          # ls -la /run/virtinterfaced.pid
135          -rw-r--r-- 1 root root 6 Jul  9 02:40 /run/virtinterfaced.pid
