virtstoraged - libvirt storage pool management daemon

virtstoraged [/OPTION/]…

The virtstoraged 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 storage pools.

The virtstoraged daemon only listens for requests on a local Unix domain socket. Remote off-host access and backwards compatibility with legacy clients expecting libvirtd is provided by the virtproxy daemon.

Restarting virtstoraged 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.

The virtstoraged daemon is capable of starting in two modes.

In the traditional mode, it will create and listen on UNIX sockets itself.

In socket activation mode, 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/virtstoraged.conf will no longer have any effect.

Socket activation mode is generally the default when running on a host OS that uses systemd. To revert to the traditional mode, all the socket unit files must be masked:

#+begin_quote

      $ systemctl mask virtstoraged.socket virtstoraged-ro.socket \
         virtstoraged-admin.socket

#+end_quote

-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.

On receipt of SIGHUP virtstoraged will reload its configuration.

To retrieve the version of virtstoraged:

#+begin_quote

      # virtstoraged --version
      virtstoraged (libvirt) 7.10.0

#+end_quote

To start virtstoraged, instructing it to daemonize and create a PID file:

#+begin_quote

      # virtstoraged -d
      # ls -la /run/virtstoraged.pid
      -rw-r--r-- 1 root root 6 Jul  9 02:40 /run/virtstoraged.pid

#+end_quote
