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： A technique for performing configuration checking of a network is provided. A network data store is scanned for at least one transaction. At least one event is generated for the transaction. At least one configuration policy is associated with the event. The configuration policy is compared with configuration data associated with the event. It is determined whether the configuration policy has been violated based on the comparison.

摘要： According to one aspect of the present disclosure, a method and technique for shared versioned workload partitions is disclosed. The method includes: creating, in a host machine running an instance of a first version of an operating system, a first workload partition associated with a second version of the operating system, the second version of the operating system comprising a different version of the operating system than the first version of the operating system; creating, in the logical partition, a second workload partition associated with the second version of the operating system; and hierarchically linking the second workload partition to the first workload partition to enable sharing of resources of the first workload partition by the second workload partition.

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： 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： A mechanism is provided for isolation of device namespace to allow duplicate or common names in root volume group workload partitions. The mechanism creates a scratch file system that contains enough information to create an execution environment for a workload partition and information about which physical volumes to use for the root volume group file systems. The mechanism then populates the root file systems on a disk in the global space. The mechanism boots the workload partition from the scratch file system and configures the devices to be exported to the workload partition based information in the scratch file system. The mechanism then renames the logical volume names to the traditional names. The mechanism then temporarily mounts the root volume group file system onto the scratch file system.

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.
