Provided is a virtual interface, a 'Forwarder' and a Virtual Block Storage Device (VBSD). The virtual interface is the interface between a Command/Response Queue (CRQ), which receives CRQ commands from a virtual machine monitor, and a common interface of the Forwarder. The Forwarder receives I/O commands in a format associated with the common interface and converts the commands into a generic I/O format. The reformatted command is transmitted to the VBSD. The virtual machine monitor sends a read or write (R/W) request to the virtual interface, which passes the request to the Forwarder. The Forwarder receives the request, converts the request into a form readable by the VBSD and transmits the converted request to the VBSD. The VBSD transmits the request to a block storage device and returns the response to the Forwarder. The Forwarder replies to the request from the virtual interface with the response from the ABSD. The virtual interface then responds to the virtual machine monitor.

The Forwarder receives I/O commands in a format associated with the common interface and converts the commands into a generic I/O format. The reformatted command is transmitted to the VBSD. The hypervisor sends a read or write (R/W) request to the virtual interface, which passes the request to the Forwarder. The Forwarder receives the request, converts the request into a form readable by the VBSD and transmits the converted request to the VBSD. The VBSD transmits the request to a block storage device and returns the response to the Forwarder. The Forwarder replies to the request from the virtual interface with the response from the ABSD. The virtual interface then responds to the hypervisor.

An embodiment of the invention pertains to debugging program code associated with graphical objects, wherein the code responds to events of user interactions with the object. A menu is generated that includes user interaction events, and an associated program window is adapted to present the menu to a user when requested, wherein the user can select user interaction events from the menu. For each selected event, the method identifies a component of the program code that is responsive to that selected event. The method further includes setting a breakpoint in the program code in selected relationship with each identified program code component, wherein the subsequent occurrence of one of the selected user interaction events triggers a corresponding one of the breakpoints.

In a method for creating a social networking check-in location for social networking applications, a computer receives a geographic location for each user computing device in a plurality of user computing devices. The computer determines a portion of the plurality of user computing devices that exhibit an area density exceeding a threshold. The area density is defined as a number of user computing devices per unit area. The computer receives two or more social networking messages from the portion of the plurality of user computing devices. The computer determines a common subject between the two or more social networking messages. The computer creates a social networking check-in location.

Provided is conduit configured such that a hypervisor does not need to include logic for communicating directly with an I/O storage device. A virtual Asynchronous Service Interface (VASI) is the interface between a Command/Response Queue (CRQ), which receives CRQ commands from the hypervisor, and a Common Data-Link Interface (CDLI) of a Forwarder. The Forwarder receives I/O commands in a format associated with the CDLI and converts the commands into a generic I/O format understood by a Virtual Block Storage Device (VBSD). The reformatted command is transmitted to the VBSD, which issues commands to the native I/O stack. The hypervisor sends a read or write (R/W) request to the VASI, which passes the request to the Forwarder. The Forwarder converts the request and transmits the converted request to the VBSD. The VBSD transmits the request to the block storage device and returns the response to the Forwarder. The Forwarder replies to the request from the VASI with the response from the ABSD. The VASI then responds to the hypervisor. Also provided is an operation-specific module responsible for understanding and the intelligent processing of data that is transmitted between the hypervisor and the I/O stack.

A computer implemented method, data processing system, and apparatus for hardware resource arbitration in a data processing environment having a plurality of logical partitions. A hypervisor receives a request for a hardware resource from a first logical partition, wherein the request corresponds to an operation. The hypervisor determines the hardware resource is free from contention by a second logical partition. The hypervisor writes the hardware resource to a hardware resource pool data structure, as associated with the first logical partition, in response to a determination the hardware resource is free. The hypervisor presents the hardware resource to the first logical partition. The hypervisor determines that the operation is complete. The hypervisor release the hardware resource from a hardware resource pool, responsive to the determination that the operation is complete.

A method for selective link aggregation in a virtualized data processing environment is provided in the illustrative embodiments. A data packet is received at a switch. An identifier associated with the data packet is determined. The identifier corresponds to a logical partition in a logical partitioned data processing system. A lookup is performed in a data structure to determine a set of ports associated with the identifier. The set of ports is retrieved from the data structure. A port is selected from the set of ports and the data packet is transmitted from the port to the logical partition.

In some example embodiments, there is a method for failback to a primary communications adapter. The method includes receiving, in a driver for the primary communications adapter and a backup communications adapter, a link up event for the primary communications adapter, wherein the link up event is sent from the primary communications adapter to the driver, and wherein the link up event is triggered by establishing electrical connectivity to the primary communications adapter. The method includes inferring that the primary communications adapter is configured for receiving packets. The method includes setting the backup communications adapter to idle, wherein the backup communications adapter receives packets and drops the packets while idle. The method includes activating the primary communications adapter, wherein the primary communications adapter receives packets and passes the packets up a protocol stack while activated.

A method and apparatus are provided for use with a SEA or other bridge device, which is positioned between virtual and physical LANS and is adapted to monitor connection setup packets. If the SEA detects such a packet, it determines whether it can accommodate the MSS value listed in the packet. In one embodiment, a method is provided for implementation by a bridge device positioned to transfer data packets between a specified LPAR system arid a specified host. The method comprises the step of detecting a packet that is transmitted to the bridge device, in order to set up a connection between the LPAR system and the host. The method further comprises determining whether the detected packet indicates an initial MSS value for the connection that is greater than a prespecified MSS value. Upon determining that the detected packet indicates an initial MSS value that exceeds the prespecified MSS value, the packet is altered to establish the prespecified MSS value as the MSS value for the connection.

Where parallel links between network devices are aggregated into link groups to support the transport of associated data streams, the link groups can be managed in an energy efficient manner by defining each link group as consisting of a primary link and one or more secondary links. The primary link in a link group remains enabled at all times but the secondary links are enabled only when needed and are disabled when no longer needed, minimizing power consumption for the secondary links (and the link group).
