Abstract
A dynamic migration apparatus of a system logically divides hardware resources of a physical machine to configure a plurality of logical partitions using the pass-through I/O method and performs migration on the logical partitions. The apparatus makes a setting so that the same I/O device used in a migration source logical partition continues to be used in a migration destination logical partition when migration is performed.
Claims13
A dynamic migration apparatus of a system that logically divides hardware resources of a physical machine to configure a plurality of logical partitions using a pass-through I/O method, and performs migration on the logical partitions,
- the dynamic migration apparatus making a setting so that the same I/O device used in a migration source logical partition continues to be used in a migration destination logical partition when migration is performed.
A dynamic migration method of a system that logically divides hardware resources of a physical machine to configure a plurality of logical partitions using a pass-through I/O method, and performs migration on the logical partitions,
- the dynamic migration method including making a setting so that the same I/O device used in a migration source logical partition continues to be used in a migration destination logical partition when migration is performed.
A computer-readable medium stored therein a dynamic migration program of a system that logically divides hardware resources of a physical machine to configure a plurality of logical partitions using a pass-through I/O method, and performs migration on the logical partitions,
- the dynamic migration program making a computer function as a dynamic migration apparatus that makes a setting so that the same I/O device used in a migration source logical partition continues to be used in a migration destination logical partition when migration is performed.
