Linux Containers (LXC) is a toolset in Linux that creates an isolated environment in a single host. Specifically, the LXC creates environments isolated from each other regarding computing resources and root filesystems using the Linux kernel’s namespaces and cgroups function.

vs. VM | One distinction between the LXC and the virtual machines (VMs) is that different LXC instance shares the same operating system (OS) kernel. On the other hand, the VMs share only the physical hardware they each run their own OS stack, including the kernel.

vs. Docker | We can consider the distinction between the two different container solutions from how they are used. Specifically, the Docker container is designed to run a single process per container. This paradigm is also commonly known as application-level isolation. On the other hand, the LXC is meant for running a full-fledged OS in isolation. The community typically uses LXC as a lightweight alternative to the VM where the container is created as a base from which modification is made on top of it. In contrast, the Docker container is not intended to be modified after it has been created.
