       lxc-create - creates a container


       lxc-create {-n name} [-f config_file] {-t template} [-B backingstore] [-- template-


       lxc-create creates a system object where is stored the configuration information and where
       can be stored user information. The identifier name is used to specify the container to be
       used with the different lxc commands.

       The object is a directory created in /var/lib/lxc and identified by its name.

       The object is the definition of the different resources an application can use or can see.
       The  more  the configuration file contains information, the more the container is isolated
       and the more the application is jailed.

       If the configuration file config_file is not specified, the container will be created with
       the default isolation: processes, sysv ipc and mount points.


       -f, --config config_file
              Specify  the  configuration  file  to  configure  the  virtualization and isolation
              functionalities for the container.

       -t, --template template
              'template' is the short name of an existing 'lxc-template' script that is called by
              lxc-create,  eg. busybox, debian, fedora, ubuntu or sshd.  Refer to the examples in
              /usr/share/lxc/templates  for   details   of   the   expected   script   structure.
              Alternatively, the full path to an executable template script can also be passed as
              a parameter.  "none" can be used to force lxc-create to skip rootfs creation.

       -B, --bdev backingstore
              'backingstore' is one of 'dir', 'lvm', 'loop', 'btrfs', 'zfs',  'rbd',  or  'best'.
              The  default  is  'dir',  meaning  that  the  container  root  filesystem will be a
              directory under /var/lib/lxc/container/rootfs.  This backing store type allows  the
              optional  --dir ROOTFS to be specified, meaning that the container rootfs should be
              placed under the specified path, rather than the default. (The 'none'  backingstore
              type  is  an  alias for 'dir'.) If 'btrfs' is specified, then the target filesystem
              must be btrfs, and the container rootfs will be created as a  new  subvolume.  This
              allows  snapshotted clones to be created, but also causes rsync --one-filesystem to
              treat it as a separate filesystem.  If backingstore is 'lvm',  then  an  lvm  block
              device  will  be  used  and  the  following further options are available: --lvname
              lvname1 will create an LV named lvname1 rather  than  the  default,  which  is  the
              container  name. --vgname vgname1 will create the LV in volume group vgname1 rather
              than the default, lxc.   --thinpool  thinpool1  will  create  the  LV  as  a  thin-
              provisioned  volume  in  the  pool  named  thinpool1  rather than the default, lxc.
              --fstype FSTYPE will create an  FSTYPE  filesystem  on  the  LV,  rather  than  the
              default,  which  is  ext4.  --fssize SIZE will create a LV (and filesystem) of size
              SIZE rather than the default, which is 1G.

              If backingstore is 'loop', you can use --fstype FSTYPE and --fssize SIZE as  'lvm'.
              The default values for these options are the same as 'lvm'.

              If  backingstore  is  'rbd',  then  you  will need to have a valid configuration in
              ceph.conf and a ceph.client.admin.keyring defined.  You can specify  the  following
              options : --rbdname RBDNAME will create a blockdevice named RBDNAME rather than the
              default, which is the container name.  --rbdpool POOL will create  the  blockdevice
              in the pool named POOL, rather than the default, which is 'lxc'.

              If  backingstore  is  'best',  then  lxc  will  try, in order, btrfs, zfs, lvm, and
              finally a directory backing store.

       -- template-options
              This will pass template-options to the template as arguments. To see  the  list  of
              options supported by the template, you can run lxc-create -t TEMPLATE -h.


       These options are common to most of lxc commands.

       -?, -h, --help
              Print a longer usage message than normal.

              Give the usage message

       -q, --quiet
              mute on

       -P, --lxcpath=PATH
              Use an alternate container path. The default is /var/lib/lxc.

       -o, --logfile=FILE
              Output to an alternate log FILE. The default is no log.

       -l, --logpriority=LEVEL
              Set log priority to LEVEL. The default log priority is ERROR. Possible values are :

              Note that this option is setting the priority of the events log  in  the  alternate
              log file. It do not have effect on the ERROR events log on stderr.

       -n, --name=NAME
              Use  container identifier NAME.  The container identifier format is an alphanumeric

              Specify the configuration  file  to  configure  the  virtualization  and  isolation
              functionalities for the container.

              This  configuration  file  if  present  will  be  used  even  if there is already a
              configuration file present in the previously created container (via lxc-create).

              Show the version number.


       The container already exists
              As the message mention it, you try to create a container but there is  a  container
              with the same name. You can use the lxc-ls command to list the available containers
              on the system.
