支持操作系统及类似环境虚拟化执行的虚拟机监控器和容器运行时系统
抽象与分配计算资源，承载虚拟机或容器运行的基础软件。
类别解释
Hypervisors and container runtime systems that support virtualised execution of operating systems
虚拟机监控器是对计算资源进行抽象或分配，使逻辑上相互隔离或与物理硬件隔离的虚拟机得以执行、管理及编排的数字要素软件产品，可直接运行于硬件（裸机）、操作系统之上，或另一虚拟机内部（嵌套虚拟化）。本类别包括第 1 类（裸机型）、第 2 类（托管型）和混合型虚拟机监控器。容器运行时系统是管理在单一宿主操作系统上作为隔离进程运行的容器的执行及生命周期、并负责资源分配的软件产品。
English
Hypervisors abstract and/or allocate computing resources and enable the execution, management and orchestration of virtual machines that are logically separated from each other or from the physical hardware; they may run directly on hardware (bare metal), on top of an operating system, or inside another virtual machine (nested virtualisation). The category includes type 1, type 2 and hybrid hypervisors. Container runtime systems manage the execution and lifecycle of containers running as isolated processes on a single host operating system and allocate their resources.
CRA 附件三 II 类，技术描述见实施条例 (EU) 2025/2392 附件一第 1–4 项（Class II 表）

必须采用模块 B+C 或模块 H，由公告机构对产品设计或质量体系开展第三方合格评定。
Module B+C or Module H is mandatory, with a notified body assessing the product design or the quality management system.
重要产品 · II 类的主要义务
满足该类别的更高安全强度要求，产品设计需经公告机构审查。
取得欧盟型式检验证书（模块 B+C）或经质量体系评估（模块 H）后方可加贴 CE 标识。
重大修改须重新评估，并按要求接受公告机构的定期审核。
English
- Meet the higher security level of the category; the design is assessed by a notified body.
- Affix the CE marking only after an EU-type examination certificate (Module B+C) or quality system assessment (Module H).
- Substantial modifications require re-assessment, and periodic audits by the notified body apply.
