Abstract: In an approach to intelligent connection placement across multiple logical ports, a mapping table for a virtual machine is created. Responsive to determining that an entry exists in the mapping table for the port on the peer device, whether a virtual function exists the port on the peer device in the mapping table for the same physical function is determined. A virtual function is selected from the mapping table to connect the local port to the port on the peer device.

Abstract: Virtual machine mobility for virtual machine using remote direct memory access (RDMA) connections, including: receiving a virtual machine (VM) mobility request to transfer a virtual machine from a source host to a destination host; migrating application data transfer from an RDMA connection of the virtual machine to a Transmission Control Protocol (TCP) connection of the virtual machine, wherein the RDMA connection and the TCP connection are facilitated by a physical network adapter; migrating the TCP connection to a virtual network adapter of the virtual machine; and transferring the virtual machine from the source host to the destination host.

Abstract: Techniques for managing communications between applications executing in a distributed computing environment are presented. An example method includes detecting, by a first virtual machine, that an application has migrated from a source virtual machine to a destination virtual machine in the distributed computing environment. The first virtual machine identifies a location of the destination virtual machine in the distributed computing environment. Based on the identified location, the first virtual machine generates one or more routing rules for communications between applications executing on the first virtual machine and the migrated application, wherein the one or more routing rules comprise rules that minimize latency and processing overhead for communications with the migrated application in the distributed computing environment.

Abstract: An embodiment of the invention is associated with a virtualized environment that includes a hypervisor, client LPARs, and virtual servers that each has a SEA, wherein one SEA is selected to be primary SEA for connecting an LPAR and specified physical resources. A first SEA of a virtual server sends a call to the hypervisor, and in response the hypervisor enters physical adapter capability information, contained in the call and pertaining to the first SEA, into a table. Further in response to receiving the call, the hypervisor decides whether or not the first SEA of the virtual server should then be the primary SEA. The hypervisor sends a return call indicating its decision to the first SEA.

Abstract: Provided is reporting session information for a session upstream from a server. A data processing system receives a session handshake from a first client for a session between the server and the first client. The system receives a session-descriptor for a session between a second client and the first client before handling a nested session. The system determines whether a user has made an upstream session request. The system obtains session data from an upstream data structure, responsive to a determination that the user has made an upstream session request. The system renders the session data based on the upstream session request.

Abstract: Techniques are disclosed for providing thread specific protection levels in a multithreaded processing environment. An associated method includes generating a group of threads in a process, one of the group of threads opening a thread entity, and that one of the group of threads specifying one or more levels of access to the thread entity for the other threads. In one embodiment, when a first of the threads attempts to perform a specified operation on the thread entity, the method includes determining whether that first thread is the one of the group of threads that opened the thread entity. When the first thread is not that one of the group of threads, the first thread is allowed to perform the specified operation if and only if such operation is permitted by the specified one or more levels of access.
