  • Patent number: 9626180
    Abstract: Mechanisms are provided for performing a live update of an operating system. The mechanisms receive an update to an operating system and clone a root volume group associated with an operating system instance executing in a first logical partition of the data processing system to generate a cloned root volume group. The mechanisms apply the update to the cloned root volume group to generate an updated and cloned root volume group and boot a second logical partition of the data processing system using the updated and cloned root volume group. Moreover, the mechanisms migrate application instances and application data to the second logical partition.

    Abstract: Mechanisms are provided for performing a live update of an operating system. The mechanisms receive an update to an operating system and clone a root volume group associated with an operating system instance executing in a first logical partition of the data processing system to generate a cloned root volume group. The mechanisms apply the update to the cloned root volume group to generate an updated and cloned root volume group and boot a second logical partition of the data processing system using the updated and cloned root volume group. Moreover, the mechanisms mirror the original root volume group associated with an operating system instance executing in a first logical partition and import the mirrored root volume group into the second logical partition. The mechanisms migrate application instances to the second logical partition by restarting the application instances in the second logical partition using the mirrored root volume group.

  • Patent number: 8930967
    Abstract: 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.

  • Publication number: 20140040609
    Abstract: 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 extension may be shared by a second instance of the operating system. An indicator accessible only to the second instance of the operating system records an indication that the first instance of the operating system requested to load the kernel extension. The kernel extension is loaded. A request is received by the first instance of the operating system to remove the functionality from the kernel. The functionality is removed from the kernel in response to determining, based on the indicator, that the first instance of the operating system had previously requested to load the kernel extension.

  • Patent number: 8578214
    Abstract: 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.

  • Patent number: 8527989
    Abstract: 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.

  • Patent number: 8448169
    Abstract: 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 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.
