摘要： A first of a plurality of virtual operating system instances requests a device identifier for a device to be configured by the first virtual operating system instance within an execution space of the first virtual operating system instance. In response, a device identifier data structure maintained in a kernel space is accessed, and a device identifier that is available is determined. An indication in the device identifier data structure that the device identifier is no longer available is recorded. The device identifier is returned from the kernel space to the first virtual operating system instance. The first virtual operating system instance assigns the device identifier to the device.

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： Some embodiments of the inventive subject matter are directed to detecting a file that a first instance of an operating system is configured to load where the file is configured to extend functionality of a kernel when loaded. In some embodiments, the first instance of the operating system is managed by a second instance of the operating system (e.g., the first instance of the operating system is a virtual operating system and the second instance is a global operating system). The first and second instances of the operating system share the kernel. Some embodiments are further directed to generating a unique electronic identifier based on properties of the file. The unique electronic identifier uniquely identifies the file. Some embodiments are further directed to providing a copy of the file to the first instance of the operating system, and some time later, receiving a request from the first instances of the operating system to load the copy of the file. Some embodiments are further directed to determining, using the unique electronic identifier, that the copy of the file from the first instance of the operating system is equivalent to the file. Some embodiments are further directed to loading the copy of the file in response to determining, using the unique electronic identifier, that the copy of the file is equivalent to the file. The loading extends the functionality of the kernel.

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 recording an indicator that indicates that the first of the plurality of the instances of the operating system requested to load the kernel extension, where the indicator is accessible only to the second instance of the operating system. In some embodiments, the method is further directed to loading the kernel extension, where loading the kernel extension extends functionality of the kernel. In some embodiments, the method is further directed to receiving a request by the first instance of the operating system to remove the functionality from the kernel and determining, based on the indicator, that the first instance of the operating system had previously requested to load the kernel extension. In some embodiments, the method is further directed to removing the functionality from the kernel in response to the determining, based on the indicator, that the first instance of the operating system had previously requested to load the kernel extension.

摘要： When moving workload partitions (WPARs) from machine to machine, operating systems may encounter errors that prevent successful WPAR migration. Recording and reporting errors can be challenging. To move WPARs, the operating system may employ a plurality of software components, such as code residing in user space (e.g., application programs, OS libraries, and shell scripts), code residing in the operating system's kernel, and code residing on remote machines. Embodiments of the invention include a framework that enables all the software components to record errors. The framework can also report the errors to users and processes.
摘要翻译：将工作负载分区（WPAR）从机器移动到另一台机器时，操作系统可能会遇到阻止WPAR成功迁移的错误。记录和报告错误可能会带来挑战。为了移动WPAR，操作系统可以使用多个软件组件，例如驻留在用户空间（例如，应用程序，OS库和shell脚本）中的代码，驻留在操作系统内核中的代码以及驻留在远程机器上的代码。本发明的实施例包括使得所有软件组件能够记录错误的框架。框架还可以向用户和进程报告错误。
