LXD is a management layer for LXC containers, which lets you do things like move/copy containers (to another host), start/stop them, create/attach/detach profiles (network settings), attach/manage various kinds of storage, etc. LXD also can manage libvirt/KVM/QEMU virtual machines in an almost identical way, so you can mix LXC containers and full VMs and manage them in the same way.
