 +===== Transfer image and checksum to new LXD host =====
 +<code>

 +
 +Transferring image: 100%
 +
 +<code>lxc launch image_name container_name </code>
 +Creating container_name
 +Starting container_name
 +
 +In some instances the publish command may lead to a split xz tar-ball --- but both formats are supported. Simply import the meta-data and rootfs components with
 +
 +    lxc image import <metadata tarball> <rootfs tarball> --alias image_name
 +=== Edit LXD default profile: networking ===
 +
 +Put lxc network interface to host network
 +
 +<code>
 +lxc stop lxc-docuwiki 
 +lxc profile device set default eth0 parent ens3
 +lxc profile device set  default eth0 nictype macvlan
 +service lxd restart
 +service lxd-containers restart </code>
 +
 +launch your container
 +<code>
 +lxc start lxc-docuwiki 
 +lxc exec lxc-docuwiki /bin/bash
 +
 +</code>
