LXCFS is a small FUSE filesystem written in C that makes Linux containers feel more like virtual machines. It bind-mounts container-aware versions of crucial procfs files (cpuinfo, meminfo, uptime, etc.) so values reflect the container rather than the host.
Use cases
- make containers report correct /proc/uptime and /proc/meminfo
- show cgroup-aware cpu and memory values inside containers
- run systemd in unprivileged LXC containers with cgroup access
- mask host procfs entries for container isolation
- make container resource limits visible to tools reading /proc
When to choose
- you run LXC or Incus containers and want VM-like /proc visibility
- tools inside containers misreport resources because they read host procfs
- you need cgroup-aware proc values on older kernels without cgroup namespaces
When to avoid
- you only use Docker or Kubernetes, which have their own proc masking
- your kernel's cgroup namespaces already provide the isolation you need
- you need a general-purpose FUSE filesystem rather than proc masking
