NAME

       guestfsd - guestfs daemon

SYNOPSIS

        guestfsd [-r] [-v|--verbose]

DESCRIPTION

       "guestfsd" is the libguestfs daemon.  Normal users never need to run
       this program explicitly.  This man page discusses what "guestfsd" does
       in both the libguestfs appliance and when using libguestfs live.

   LIBGUESTFS APPLIANCE
       For the architecture of the libguestfs appliance, see "ARCHITECTURE" in
       guestfs(3).

       After the appliance boots, the /init script in the appliance starts
       "guestfsd" with no arguments.  "guestfsd" opens the virtio-serial port
       on a known path (see "FILES").  It initiates the protocol (see
       "COMMUNICATION PROTOCOL" in guestfs(3)) and processes requests one at a
       time from the library until the appliance is destroyed.

       Filesystems are mounted under /sysroot and all filesystem operations
       happen relative to this directory.

   LIBGUESTFS LIVE
       In the libguestfs live case, "guestfsd -r" is started from the rc-
       scripts, systemd, etc.

       The "-r" option causes the daemon to operate on the root filesystem
       instead of /sysroot.

       Currently (because of limitations in virtio-serial) only one client can
       connect at a time, and "guestfsd" must be restarted after each client
       disconnects.  If libguestfs live were changed to use a different
       transport such as TCP/IP then this limitation could be removed.

OPTIONS

       -?
       --help
           Display brief help.

       -c CHANNEL
       --channel CHANNEL
       --channel fd:N
           Pass the name of the virtio-serial channel, serial port, etc.  over
           which guestfsd will communicate with the library.  If this
           parameter is not given, then an internal default port is used.

           The "fd:N" form causes guestfsd to use the file descriptor "N"
           directly.

       -l
       --listen
           Instead of opening the "guestfs_channel" and thus expecting that it
           already exists, create the channel as a Unix domain socket, listen
           on it, and accept a single connection.  This is mainly used for
           testing the daemon.

       -n
       --network
           Enable network features in the daemon.

       -r  Set the root filesystem to be / (instead of the default which is
           /sysroot).  Also do not unmount filesystems when the daemon exits.

           This option is used to enable libguestfs live.

       -v
       --verbose
           Enable verbose messages for debugging.

           The verbose flag is also set if the Linux command line contains the
           substring "guestfs_verbose=1".

EXIT STATUS

       This program returns 0 if successful, or non-zero if there was an
       error.

FILES

       /dev/virtio-ports/org.libguestfs.channel.0
           The virtio serial port which "guestfsd" connects to.

       /proc/cmdline
           The Linux command line is parsed to discover "guestfs_*" flags.
           The following flags are understood:

           guestfs_verbose=1
               Enable verbose messages.  This flag is passed by the libguestfs
               library to the appliance to make the daemon more verbose (it
               acts like the -v flag on the command line).  Unrelated to the
               daemon, it also causes the appliance init script to print out a
               lot more debugging information.

           guestfs_channel=PATH
               Set the path to the virtio-serial channel to something other
               than the default (which is
               /dev/virtio-ports/org.libguestfs.channel.0).  This is used by
               the User-Mode Linux backend to use a regular emulated serial
               port instead of virtio-serial.

           guestfs_network=1
               This is set if the appliance network is enabled (see
               "guestfs_set_network").
