Questions tagged [lxd]

The LXD tag is for questions relating to the LXD daemon based on liblxc, providing REST API, command line tool and OpenStack integration plugin for LXC.

From the Linux Containers LXD Introduction page:

LXD is a container "hypervisor" and a new user experience for LXC.

Specifically, it's made of three components:

  • A system-wide daemon (lxd)
  • A command line client (lxc)
  • An OpenStack Nova plugin (nova-compute-lxd)
