What Linux container systems do you know?

Question

linux

I heard earlier that there are software solutions based on chroot and virtualization that allow you to run an application in a limited secure environment. So, which ones exist?

Answer 1

virtualbox, docker e.g.
kvm could be attributed even though it's not an
openvz container

Answer 2

LXC, enough about settings here: LXC containers

Answer 3

In fact, only three are alive - LXC, openvz / Virtuozzo, porto. (Docker is based on LXC a little more than completely).
The rest are no longer being developed and/or are not compatible with more or less up-to-date kernels (even RH ones).
