Abstract: A computer system has: a virtual machine operating on a physical machine; and a management block operating on the physical machine and managing the virtual machine. The virtual machine has a specific function processing module that performs specific function processing with respect to a packet for transmission and a received packet. The management block has a virtual switch that relays a packet transmitted and received by the virtual machine. The virtual switch has an offload processing block that performs the specific function processing if the specific function processing is offloaded to the management block. If the specific function processing is offloaded from the virtual machine to the management block, the specific function processing module notifies the management block of processing information required for the specific function processing, and the offload processing block executes the specific function processing based on the processing information received from the virtual machine.

Abstract: Non-limiting examples of the present disclosure describe decoupling task state tracking that is managed by a shared task completion platform from execution of tasks by a task resource owner. Task registration data is received at a shared task state platform for a task that is executable by a task owner resource. Task registration data comprises parameters to be collected for execution of the task and ancillary information, such as the name of the task and whether to confirm the values of the parameters after collection. During interaction with a user, the shared task completion platform receives an input and determines the task is associated with the received input. During the interaction, parameters of the received task registration data are utilized to collect data for execution of the task. The collected data is transmitted to the task owner resource for execution of the task.

Abstract: Method and system for serializing access to datasets, suitable for use in a workflow management system which executes multiple business processes, wherein a single process instance is enabled to invoke web services which may update datasets of different storages holding redundant information. Business Process Execution Language for Web Services allows defining business processes that make use of web services and business processes that externalize their functionality as web services. As the business process has no knowledge about data that is accessed by invoked web services, concurrent process instances may update the same pieces of information within a database. Unless access to the data is carried out as a transaction, parallel execution of the process instances may cause data inconsistencies, which may be avoided by serializing the execution of process instances based on correlation information associated with messages consumed by the process instances.

Abstract: Approaches for ensuring the privacy and integrity of a hypervisor. A host operating system manages a set of resources. The host operating system is prevented from accessing a portion of the resources belonging to or allocated by the hypervisor. The host operating system may be prevented from accessing resources belonging to or allocated by the hypervisor by transferring execution of the host operating system into a virtual machine container that does not have sufficient privilege to access any portion of the memory pages in which the hypervisor is executing. After the host operating system provides a requested resource to the hypervisor, the hypervisor may use a hardware component that establishes and enforces constraints on what portions of memory the host operating system is allowed to access to protect the requested resource from the host operating system.

Abstract: Processing within a computing environment that supports pageable guests is facilitated. Processing is facilitated in many ways, including, but not limited to, associating guest and host state information with guest blocks of storage; maintaining the state information in control blocks in host memory; enabling the changing of states; and using the state information in management decisions. In one particular example, the guest state includes an indication of usefulness and importance of memory contents to the guest, and the host state reflects the ease of access to memory contents. The host and guest state information is used in managing memory of the host and/or guests.

Abstract: A data communication system verifies Network Function Virtualization (NFV) parameters. The data system transfers communications for devices by executing hypervisors to generate an NFV processing environment with multiple NFV time slices. The system executes virtual Network Elements (vNEs) during the NFV time slices. The system associates the communication devices with the NFV time slices based on the execution of the vNEs during the time slices. The system yields NFV data indicating an actual NFV time slice used to transfer data communications for an individual communication device and a trusted NFV time slice for that communication device. The system transfers alert data for the communication device if the actual NFV time slice does not correspond to the trusted NFV time slice.
