Questions tagged [lxc]
Linux Containers (LXC) is a userspace interface for operating system-level virtualization features in the mainline Linux kernel, such as kernel namespaces and control groups (cgroups). These allow multiple distinct user space instances to be run on a single kernel. Note: the 3 letters "lxc" command is part of LXD, not LXC. Please use the LXD tag if your question is about LXD rather than only about LXC.
