With LXC too, and you can run LXC containers inside LXC container => 
"nested" containers.

There is no diffence beetween LXC and LXD in terms of functionalities. 
It's just the same thing !!

LXC is based on a flat configuration file, it's very simple to use, 
especially on a single host.

LXD is "cluster" oriented, based on a deamon, and containers's 
configuruations are in a database (SQLite if i rememmber).

LXD is the default on Ubuntu Server. It's a good choice fot beginers.

But I prefers "old school flat files", so i remove LXD and use "old 
style" LXC. It is more simple with complex configurations !

I was a fan of Linux-Vserver, i have wroted some scripts to play with 
VLANs, conditional routing and netfilter (this was a long time ago, 
before "veth" ...) but finally i choose LXC when it was good enough for 
"production". I use it for years (mostly over ZFS), it works like a charms.
