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…
LXD can manage VMs and can manage clusters with live migration for both containers and VMs. I don’t know if nspawn can.

But nomad also supports managing nspawn containers which is interesting.
