摘要： 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.

摘要： Controlled partition shut-down is provided within a shared memory partition data processing system including a shared memory partition, a paging service partition, a hypervisor and a shared memory pool within physical memory. The hypervisor manages access to logical pages within the pool and page-out of pages from the pool to external paging storage via the paging service partition. A respective paging service stream exists between the paging service partition and hypervisor for each shared memory partition, with each stream including a stream state. The control method includes: responsive to a shut-down initiating event, notifying the paging service partition to shut down, and determining whether a shared memory partition is currently active, and if so, signaling the hypervisor to complete paging activity for the active memory partition and waiting for its stream state to enter a suspended or a completed state before automatically shutting down the paging service partition.

摘要： 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.

摘要： A method, system, and computer usable program product for selective link aggregation in a virtualized data processing environment are 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.

摘要： A method, system and network protocol that enables each host within a virtual local area network (VLAN) environment to automatically discover to which VLANs the host belongs. When a host initially sets up a communication interface, the host generates a series of probing packets, each including a different one of the range of possible VLAN IDs within the packet header. The probing packet requests a response from the switch indicating whether the corresponding VLAN (identified by the VLAN ID) is supported by the switch. The switch automatically drops any packets with a VLAN ID not recognized/supported/configured in the switch. The destination device only receives supported packets, and thus the interface only receives a response for those request packets having a VLAN ID associated with a supported VLAN. The host's interface then knows which VLAN ID(s) are supported, and the host assigns/utilizes only those VLAN IDs for outgoing traffic.
