摘要： Methods and systems for migrating a virtual machine instance between devices include one or more migration risk rules, each migration risk rule relating to a validation set having one or more validation substasks. A processor is configured to score a received migration request against one or more of the migration risk rules to generate one or more scores for the migration request, to compare each score to a respective threshold to determine if a level of risk according to the respective rule merits performing validation for the validation set, to validate the migration request by only those validation sets that correspond to the scores that exceed the respective threshold, and to trigger migration of a virtual machine to a target device in accordance with the migration request if none of the validation sets fail to validate the migration request.

摘要： A mechanism is provided for sharing resources allocated to an entitled virtual machine (VM). A blocked domain is created around the entitled VM and one or more processors allocated to the entitled VM. A first dispatching algorithm is implemented that prevents the dispatching of processes from other operating systems within other VMs to the one or more processors allocated to the entitled VM. Responsive to utilization of the one or more processors allocated to the entitled VM falling below a predetermined threshold, a second dispatching algorithm is implemented that allows dispatching of processes from the other operating systems within the other VMs to the one or more processors allocated to the entitled VM.

摘要： Methods for migrating a virtual machine instance between devices include scoring a received migration request against one or more rules in a rule database relating to one or more respective validation sets. Each validation set includes one or more validation subtasks. Each score is compared to a respective threshold to determine if a level of risk according to the respective rule merits performing validation. The migration request is validated by one or more validation sets that correspond to the scores that exceed the respective threshold.

摘要： Mechanisms are provided for performing a floating point arithmetic operation in a data processing system. A plurality of floating point operands of the floating point arithmetic operation are received and bits in a mantissa of at least one floating point operand of the plurality of floating point operands are shifted. One or more bits of the mantissa that are shifted outside a range of bits of the mantissa of at least one floating point operand are stored and a vector value is generated based on the stored one or more bits of the mantissa that are shifted outside of the range of bits of the mantissa of the at least one floating point operand. A resultant value is generated for the floating point arithmetic operation based on the vector value and the plurality of floating point operands.

摘要： A mechanism is provided for offloading an input/output (I/O) completion operation. Responsive to a second processor identifying that a flag has been set by a first processor requesting assistance in completing an I/O operation, the second processor copies an I/O response from a first I/O response data structure associated with the first processor to a second I/O response data structure associated with the second processor. The second processor deletes the I/O response from the first I/O response data structure, clears the flag, and processes the I/O operation by addressing the I/O response in the second I/O response data structure. Responsive to completing the I/O operation, the second processor deletes the I/O response from the second I/O response data structure.

摘要： Methods for migrating a virtual machine instance between devices include scoring a received migration request against one or more rules in a rule database to generate one or more scores for the migration request. Each rule relates to one or more respective validation sets. Each score is compared to a respective threshold. The migration request is validated by only those validation sets that correspond to the scores that exceed the respective threshold. A virtual machine is migrated to a target device in accordance with the migration request responsive to successful validation by the validation sets used.
