From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I suggest anyone considering LXD also give nspawn a look. May or may not suit your needs better.
LXD can manage VMs and can manage clusters with live migration for both containers and VMs. I don't know if nspawn can.
No software is capable of doing live migration/high availability for pet type containers and virtual machines except lxd.
But nspawn isn't really a management software like lxd is, it's more of a container runtime like lxc is.
Ninja edit: Did some googling and I'm technically wrong. Hashicorp's nomad supports lxc as a driver, but according to the doc it only supports host networking...

But nomad also supports managing nspawn containers which is interesting.
Afaik Lxd doesn't do live migration of lxc, only vms
Same as proxmox
Damn you're right:
https://documentation.ubuntu.com/lxd/en/latest/howto/move_instances/#live-migration-containers
It can live migrate cattle type containers if you enable some options, but not pet type (systemd) containers.
