Linux Kernel

The Linux kernel manages processes, memory, devices, filesystems, and networking for a Linux system. Containers typically share their host's kernel, while virtual machines run a separate guest kernel behind a virtualization boundary.

Also known as: kernel

Why it matters

Kernel capabilities affect containers, device access, and low-level tests.

Practical example

Check kernel capabilities when a test needs namespaces, privileged operations, or hardware virtualization.
