Try LXC. Ubuntu also have some extension of that, which they call LXD.
(Confusingly, the commands for managing LXC are all one word beginning
with the “lxc-” prefix, while LXD is managed via a single command
called “lxc”.)

For something even lower-level, try systemd-nspawn.

I have made a lot of use of LXC myself. It comes with templates so you
can, for example, easily install an Ubuntu userland inside a container
under Debian, or even a 32-bit container on a 64-bit OS.
