systemd-nspawn itself does not implement the namespace and cgroup mechanisms but calls kernel interfaces to combine them, so its isolation strength depends on the kernel version and configuration.

Unverifiedsystemd-nspawn is a container management tool shipped with the systemd project that uses Linux namespaces and control groups (cgroups) to isolate processes, filesystems, networking and other dimensions while sharing the kernel with the host.70% similarUnverifiedThe NT kernel employs a layered protection mechanism separating user mode from kernel mode, so a single application crash generally does not bring down the entire system, whereas the 9X kernel lacked this isolation barrier.69% similarUnverifiedContainers rely on namespaces and cgroups for logical isolation and still share the host kernel; once a privilege escalation vulnerability appears in the kernel, an attacker may cross container boundaries.65% similarUnverifiedJared通过systemd-run配合cgroups限制内存和CPU、隔离进程命名空间，为每个AI实例创建独立资源边界65% similarUnverified容器技术依赖Linux内核的namespace和cgroup机制实现进程隔离，所有容器共享同一宿主内核64% similar
