摘要： A computer implemented method, apparatus, and computer program product for obtaining an absolute path name for an open file system object. A file descriptor for the open file system object is identified in response to a process in a first software partition opening a file system object to form the open file system object. The absolute path name for the open file system object is cached in a path name field in a file structure associated with the file descriptor for the open file system object. The absolute path name for the open file system object in the path name field is used during migration of the first software partition to restore the open file system object in a second software partition.

摘要： An operating system manages virtualized instances of hardware resources and migration enabled applications partitioned into one of multiple partitions with a separate operating system kernel running in each of the partitions. A migration event controller of the operating system manages the checkpoint and restart process during migration of a virtualized instance of at least one migration enabled application from a departure partition to an arrival partition. The migration event controller supports migration enabled applications to separately specify at least one application specific checkpoint script and restart script to be triggered by checkpoint and restart events by the migration event controller so the at least one migration enabled application can participate in performing the checkpoint and restart process for additional state information during migration of the virtualized instance from the departure partition to the arrival partition.

摘要： A system and method to manage device access in a software partition are provided. The illustrative embodiments provide a mechanism for exporting resources/devices from an administrator partition to a software partition in its purview. A trusted device list data structure is provided that identifies which devices are permitted to be exported into a software partition from an administrative partition. This trusted device list data structure also identifies which of the devices in the list of devices should be exported by default when exporting devices to a software partition, i.e. if no overrides are specified. In addition, a user-specifiable mechanism to override the entries in the trusted device list data structure is provided. For security purposes, this mechanism may not be used to export devices not listed in the trusted device list data structure. The mechanism may also be used to prevent the exporting of devices which are exported by default.
摘要翻译：提供了一种在软件分区中管理设备访问的系统和方法。说明性实施例提供了将资源/设备从管理员分区导出到其职权范围内的软件分区的机制。提供了可信设备列表数据结构，其标识哪些设备被允许从管理分区导出到软件分区中。该可信设备列表数据结构还识别当将设备导出到软件分区时，默认情况下应该导出设备列表中的哪些设备，即，如果没有指定覆盖。此外，提供了用于覆盖可信设备列表数据结构中的条目的用户指定机制。出于安全考虑，此机制可能不用于导出未列在可信设备列表数据结构中的设备。该机制也可用于防止默认导出的设备的导出。
