It's easy to make your own images\n  too, either using our `distrobuilder` tool or by assembling your own image\n  tarball by hand.\n\n\n  **Containers at scale**\n\n  LXD is network aware and all interactions go through a simple REST API,\n  making it possible to remotely interact with containers on remote\n  systems, copying and moving them as you wish.\n\n  Want to go big? LXD also has built-in clustering support,\n  letting you turn dozens of servers into one big LXD server.\n\n\n  **Configuration options**\n\n  Supported options for the LXD snap (`snap set lxd KEY=VALUE`):\n   - criu.enable: Enable experimental live-migration support [default=false]\n   - daemon.debug: Increases logging to debug level [default=false]\n   - daemon.group: Group of users that can interact with LXD [default=lxd]\n   - ceph.builtin: Use snap-specific ceph configuration [default=false]\n   - openvswitch.builtin: Run a snap-specific OVS daemon [default=false]\n\n  [Documentation](https:\/\/lxd.readthedocs.io)\nsnap-id: J60k4JY0HppjwOjW8dZdYc8obXKxujRu\nchannels:\n  stable:        3.12        2019-04-16 (10601) 56MB -\n  candidate:     3.12        2019-04-26 (10655) 56MB -\n  beta:          \u2191\n  edge:          git-570aaa1 2019-04-27 (10674) 56MB -\n  3.0\/stable:    3.0.3       2018-11-26  (9663) 53MB -\n  3.0\/candidate: 3.0.3       2019-01-19  (9942) 53MB -\n  3.0\/beta:      \u2191\n  3.0\/edge:      git-eaa62ce 2019-02-19 (10212) 53MB -\n  2.0\/stable:    2.0.11      2018-07-30  (8023) 28MB -\n  2.0\/candidate: 2.0.11      2018-07-27  (8023) 28MB -\n  2.0\/beta:      \u2191\n  2.0\/edge:      git-c7c4cc8 2018-10-19  (9257) 26MB -\n<\/code><\/pre>\n
