Linux jobs run in a Linux VM of the runner's own (a WSL 2 distribution with no host mounts, interop or Docker socket on Windows; vfkit on macOS; Sysbox, or QEMU and KVM, on Linux), each in a fresh container under Sysbox inside it; on Windows 11 Pro and up, Windows jobs each run in a Windows Sandbox discarded after the job.
