LXC

 LXC, expanded as Linux Container, is a operational system level virtual machine method which can be used to host many isolated Linux containers in a single host. Though it doesn’t provide any Virtual Machine, it offers a virtual environment with its own memory, CPU, I/O, network, space and the resource control mechanism. LXC has a comprehensive process and has resource isolation. LXC is mostly written in C and has a stable and mature codebase.
