Abstract: Methods and systems configured to virtualize graphic processing services in a virtual machine environment are disclosed. A virtual machine monitor (VMM) may be configured to maintain a virtual machine (VM) based on a host operating system (OS) executing in the system. The VM may contain a virtualized graphics library (vGLib) configured to support a graphic command from an application executing in the VM. The host OS may contain a graphics library (GLib) configured to support the graphic command and utilize a graphics processing unit (GPU) in the system to process the graphic command. Upon receiving the graphic command from the application, the vGLib may be configured to allocate a memory section in the VM to store the graphic command. And the VMM may be further configured to share access to the memory section with the host OS, thereby allowing the host OS to retrieve the graphic command from the memory section and deliver the graphic command to the GLib for processing.

Abstract: A management server and method for load balancing a cluster of host computers analyzes load metrics of clients naming on the host computers in the cluster to select a first client that can be migrated from a first host computer in the cluster to a second host computer in the cluster to improve load balance for the cluster and a second client running on the second host computer that can be swapped with the first client running on the first host computer for a client swapping operation. The client swapping operation involves simultaneously migrating the first client from the first host computer to the second host computer and migrating the second client from the second host computer to the first host computer.

Abstract: Some embodiments provide a method for a system that enforces policy for a network. The method receives (i) a first set of network state data from a first cloud management application that manages a first aspect of the network and stores its network state data in a first format and (ii) a second set of network state data from a second cloud management application that manages a second aspect of the network and stores its network state data in a second format. The method stores the first and second sets of network state data in a single, unified data format. The method monitors the stored sets of network state data to determine whether the network state violates one or more network policies that constrain the network state received from the first and second cloud management applications.

Abstract: Exemplary methods, apparatuses, and systems include virtualization software of a host computer receiving a first packet addressed to a first virtual link layer address. Each of a first plurality of virtual machines on the first host computer is configured to share the first virtual link layer address. The virtualization software of the first host computer maps a flow of packets, including the first packet, to a first virtual machine within the first plurality of virtual machines and forwards the first packet to the first virtual machine. The virtualization software of the first host computer receives a second packet from the first virtual machine in response to the first packet. The second packet includes the first virtual link layer address as a source address for the first virtual machine.

Abstract: The current document is directed to methods and systems for processing, classifying, and efficiently storing large volumes of event messages generated in modern computing systems. In a disclosed implementation, received event messages are assigned to event-message clusters based on non-parameter tokens identified within the event messages. A parsing function is generated for each cluster that is used to extract data from incoming event messages and to prepare event records from event messages that more efficiently and accessible store event information. The parsing functions also provide an alternative basis for assignment of event massages to clusters.

Abstract: A method for adaptive offloading of data movement from a computer system includes identifying performance results from a plurality of SCSI extended copy (XCOPY) operations associated with a storage unit, each XCOPY operation of the plurality of XCOPY operations including one or more parameters. The method also includes selecting, based on the identified performance results, one or more XCOPY parameters for the storage unit from the plurality of XCOPY operations. The method further includes forming an XCOPY operation associated with the storage unit, the XCOPY operation including the one or more selected XCOPY parameters. The method also includes transmitting the XCOPY operation to the storage unit.

Abstract: Embodiments detect and group multiple failure events to enable batch processing of those failure events, such as in a virtual datacenter executing a plurality of virtual machines (VMs). A long timer, adaptive short timer, and adaptive polling frequency enable a computing device to efficiently detect and group the failure events that may be related (e.g., resulting from one failure). The grouped failure events are processed in parallel thereby reducing the time for recovery from the failure events.

Abstract: Embodiments perform detection and prevention of unauthorized access to files in a target folder. A filter driver, interfacing with a target folder, intercepts a first request from a process to access a file in the target folder. The filter driver returns a virtual file, along with the existing files, to the process. Upon receiving a second request from the process to write to the virtual file, the filter driver designates the process as a hostile process and prevents further access attempts.

Abstract: Guest memory data structures are read by one or more read operations which are set up to handle page faults and general protection faults generated during the read in various ways. If such a fault occurs while performing the one or more read operations, the fault is handled and the one or more read operation is terminated. The fault is handled by either dropping the fault and reporting an error instead of the fault, by dropping the fault and invoking an error handler that is set up prior to performing the read operations, or by forwarding the fault to a fault handler that is setup prior to performing the read operations. If no fault occurs, the read operations complete successfully. Thus, under normal circumstances, no fault is incurred in a read operation on guest memory data structures.

Abstract: Methods and apparatus to manage and execute action in computing environments are disclosed. An example method includes determining an identifier of a type of a computing resource identified in a received request, processing a set of stored adapters to determine an adapter associated with the identifier, determining an action associated with adapter, and presenting a user interface including a user selectable identification of the action.
