Simple definition
A Proxmox LXC container runs an isolated Linux userspace sharing its host's kernel.
Purpose and use
A Proxmox LXC container hosts a Proxmox VE-managed Linux environment using the host kernel.
How does it work?
Configuration defines resources, networking, storage and privilege options; additional mounts may receive different treatment.
Example and verification
Check backup volume coverage and identity mappings before restoration.
Points to watch
A bind mount or privileged setting does not necessarily have the same guarantees as an unprivileged container’s root volume.
In short
Mount and privilege configuration are part of container protection.
