摘要： Some embodiments of the inventive subject matter are directed to receiving a request from a first instance of an operating system (e.g., a virtual operating system) to load a kernel extension that extends functionality of a kernel, where the kernel and the first instance of the operating system are managed by a second instance of the operating system (e.g., a global operating system), and where the first and second instances of the operating system share the kernel. Some embodiments are further directed to loading the kernel extension as a shared kernel extension. Some embodiments are further directed to receiving a request by the first instances of the operating system to unload the kernel extension and determining that a third instance of the operating system (e.g., another virtual operating system also managed by the global operating system) requires the kernel extension to remain loaded. Some embodiments are further directed to notifying the first instance of the operating system that the kernel extension was unloaded while leaving the kernel extension loaded in the kernel.
摘要翻译：本发明主题的一些实施例涉及从操作系统（例如，虚拟操作系统）的第一实例接收加载扩展内核功能的内核扩展的请求，其中内核和第一实例操作系统由操作系统的第二实例（例如，全局操作系统）管理，并且操作系统的第一和第二实例共享内核。一些实施例进一步涉及将内核扩展加载为共享内核扩展。一些实施例进一步涉及接收操作系统的第一实例的请求以卸载内核扩展并且确定操作系统的第三实例（例如，由全局操作系统管理的另一个虚拟操作系统）需要内核延长保持加载。一些实施例进一步涉及在将内核扩展加载到内核中时通知操作系统的第一个实例，即内核扩展被卸载。

摘要： An OS instance can maintain management responsibility for SAN adapters to ensure separation and isolation of WPARs, while WPARs are given the capability of configuring an adapter (e.g., adding endpoint storage devices to the adapter). An operating system instance allocates an adapter to a first of a plurality of virtual operating system instances. The first virtual operating system instance updates a device data structure with an entry that indicates the adapter. The first virtual operating system instance maintains the device data structure. The first virtual operating system instance modifies the entry in the device data structure to associate a set of one or more endpoint storage devices with the adapter. The set of endpoint storage devices are provisioned to the first virtual operating system instance from a storage area network. The first virtual operating system instance configures the set of endpoint storage devices.

摘要： A method, system, and computer usable program product for isolating a workload partition space are provided in the illustrative embodiments. A boot process of a workload partition in a data processing system is started using a scratch file system, the scratch file system being in a global space. A portion of a storage device containing a file system for the workload partition is exported to the workload partition, the portion forming an exported disk. The partially booted up workload partition may discover the exported disk. The exporting causes an association between the global space and the exported disk to either not form, or sever. The exporting places the exported disk in a workload partition space associated with the workload partition. The boot process is transitioned to stop using the scratch file system and start using the data in the exported disk for continuing the boot process.
摘要翻译：在说明性实施例中提供了用于隔离工作负载分区空间的方法，系统和计算机可用程序产品。数据处理系统中的工作负载分区的引导过程使用暂存文件系统启动，暂存文件系统位于全局空间中。包含用于工作负载分区的文件系统的存储设备的一部分被导出到工作负载分区，该部分形成导出的磁盘。部分启动的工作负载分区可能会发现导出的磁盘。导出会导致全局空间与导出的磁盘之间的关联，不会形成或切断。导出将导出的磁盘放置在与工作负载分区关联的工作负载分区空间中。引导过程被转换为停止使用临时文件系统，并开始使用导出的磁盘中的数据来继续引导过程。
