gnt-network - Ganeti network administration

       The  hail  iallocator  hasn't  been updated to take networks into account in Ganeti 2.7.  The only way to
       guarantee that it works correctly is having your networks connected to  all  nodegroups.   This  will  be
       fixed in a future version.

ADDadd
       --network=*network*
       [--gateway=*gateway*]
       [--add-reserved-ips=*reserved-ips*]
       [--network6=*network6*]
       [--gateway6=*gateway6*]
       [--mac-prefix=*macprefix*]
       [--submit] [--print-jobid]
       [--no-conflicts-check]
       {network-name}

       Creates  a  new  network  with the given name.  The network will be unused initially.  To connect it to a
       node group, use gnt-network connect.  --network option is mandatory.  All other are optional.

       The --network option allows you to specify the network in a CIDR notation.

       The --gateway option allows you to specify the default gateway for this network.

       IPv6 semantics can be assigned to the network via the --network6 and  --gateway6  options.   IP  pool  is
       meaningless for IPV6 so those two values can be used for EUI64 generation from a NIC's MAC address.

       The --no-conflicts-check option can be used to skip the check for conflicting IP addresses.

       Note  that  a when connecting a network to a node group (see below) you can specify also the NIC mode and
       link that will be used by instances on that group to physically connect to this network.  This allows the
       system to work even if the parameters (eg.  the VLAN number) change between groups.

       See ganeti(7) for a description of --submit and other common options.

   MODIFYmodify
       [--gateway=*gateway*]
       [--add-reserved-ips=*reserved-ips*]
       [--remove-reserved-ips=*reserved-ips*]
       [--network6=*network6*]
       [--gateway6=*gateway6*]
       [--mac-prefix=*macprefix*]
       [--submit] [--print-jobid]
       {network}

       Modifies parameters from the network.

       Unable to modify network (IP address range).  Create a new network if you  want  to  do  so.   All  other
       options are documented in the add command above.

       See ganeti(7) for a description of --submit and other common options.

   REMOVEremove [--submit] [--print-jobid] {network}

       Deletes the indicated network, which must be not connected to any node group.

       See ganeti(7) for a description of --submit and other common options.

   LISTlist [--no-headers] [--separator=*separator*] [-v]
       [-o [+]field,...] [network-name...]

       Lists  all  existing networks in the cluster.  If no group names are given, then all groups are included.
       Otherwise, only the named groups will be listed.

       The --no-headers option will skip the initial header line.  The  --separator  option  takes  an  argument
       which denotes what will be used between the output fields.  Both these options are to help scripting.

       The -v option activates verbose mode, which changes the display of special field states (see ganeti(7)).

       The  -o option takes a comma-separated list of output fields.  If the value of the option starts with the
       character +, the new fields will be added to the default list.  This allows to quickly  see  the  default
       list plus a few other fields, instead of retyping the entire list of fields.

       The available fields and their meaning are:

       ctime  Creation timestamp

       external_reservations
              External reservations

       free_count
              Number of available addresses

       gateway
              IPv4 gateway

       gateway6
              IPv6 gateway

       group_cnt
              Number of nodegroups

       group_list
              List of nodegroups (group name, NIC mode, NIC link)

       inst_cnt
              Number of instances

       inst_list
              List of instances

       mac_prefix
              MAC address prefix

       map    Actual mapping

       mtime  Modification timestamp

       name   Name

       network
              IPv4 subnet

       network6
              IPv6 subnet

       reserved_count
              Number of reserved addresses

       serial_no
              Network object serial number, incremented on each modification

       tags   Tags

       uuid   Network UUID

   LIST-FIELDSlist-fields [field...]

       List available fields for networks.

   RENAMErename [--submit] [--print-jobid] {oldname} {newname}

       Renames a given network from oldname to newname.

       See ganeti(7) for a description of --submit and other common options.

   INFOinfo [network...]

       Displays information about a given network.

   CONNECTconnect
       [--no-conflicts-check]
       [{-N|--nic-parameters} nic-param=*value*[,*nic-param*=*value*...]]
       {network} [groups...]

       Connect a network to given node groups (all if not specified) with the network parameters defined via the
       --nic-parameters option.  Every network interface will inherit those parameters if assigned to a network.

       The --no-conflicts-check option can be used to skip the check for conflicting IP addresses.

       Passing  mode  and  link  as  positional  arguments  along  with network and groups is deprecated and not
       supported any more.

   DISCONNECTdisconnect {network} [groups...]

       Disconnect a network from given node groups (all if not specified).  This is possible only if no instance
       is using the network.

   TagsADD-TAGSadd-tags [--from file] {network} {tag...}

       Add tags to the given network.  If any of the tags contains invalid characters, the entire operation will
       abort.

       If the --from option is given, the list of tags will be extended with the contents  of  that  file  (each
       line  becomes  a tag).  In this case, there is not need to pass tags on the command line (if you do, both
       sources will be used).  A file name of - will be interpreted as stdin.

   LIST-TAGSlist-tags {network}

       List the tags of the given network.

   REMOVE-TAGSremove-tags [--from file] {network} {tag...}

       Remove tags from the given network.  If any of the tags are not  existing  on  the  network,  the  entire
       operation will abort.

       If  the --from option is given, the list of tags to be removed will be extended with the contents of that
       file (each line becomes a tag).  In this case, there is not need to pass tags on the command line (if you
       do, tags from both sources will be removed).  A file name of - will be interpreted as stdin.

       The  gnt-network  command  is  used for network definition and administration in the Ganeti system.  Each
       instance NIC can be connected to a network via the network NIC parameter.  See gnt-instance(8)  for  more
       details.
