Abstract: Embodiments associate software applications with computing resource containers based on placement rules. A placement rule indicates that a first software application is to be co-located with a second software application during execution of the first and second software applications, or that the first software application is to be separated from the second software application during execution of the first and second software applications. A target computing resource container is selected based on the placement rule and a computing resource container that is associated with the first software application. The second software application is associated with the target computing resource container, and the placement rule may be provided to the target computing resource container.

Abstract: The disclosure herein describes an intelligent chat system. During operation, the system monitors content provided by participants of an online chat, and automatically obtains, from a data source, additional information based on the monitored content. The system then presents the obtained additional information to the chat participants without the need for the chat participants to request the additional information.

Abstract: The disclosure herein describes a chat system for intelligent automatic switching between multiple chat windows. During operation, the system monitors activities occurring within the multiple chat windows and determines whether a window-switching operation is needed based on the monitored activities. In response to determining that the window-switching operation is needed, the system automatically performs the window-switching operation without the need for a user of the chat application to perform the window-switching operation manually.

Abstract: Systems and methods for performing automatic code review are described. The system receives a version of source code and processes it for potential coding issues based on a code review configuration. Upon detecting a coding issue, the system generates an automatic code review that contains a location identifying the coding issue in the version of source code and an associated review comment selected from the code review configuration. The method includes receiving a version of source code and generating a review request for a specific change in the version of source code. The method then assigns a code reviewer for handling the review request by selecting a reviewer from a subset code reviewers based on the number of times each code reviewer has been assigned to prior review requests associated with the specific change.

Abstract: Techniques for enabling a virtual machine (VM) executing on a physical node to access a partition of a storage system are described. One embodiment associates an identifier with the VM for use when communicating with the storage system, wherein the identifier differs from a default identifier of a host bust adapter (HBA) usable by the physical node to communicate with the storage system.

Abstract: The storage system exports logical storage volumes that are provisioned as storage objects. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. Logical storage volumes are created from a logical storage container having an address space that maps to storage locations of the physical data storage units. Each of the logical storage volumes so created has an address space that maps to the address space of the logical storage container. A logical storage container may span more than one storage system and logical storage volumes of different customers can be provisioned from the same logical storage container with appropriate security settings.

Abstract: The storage system exports logical storage volumes that are provisioned as storage objects. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. To facilitate creation and management of logical storage volumes, special application programming interfaces (APIs) have been developed. The special APIs include commands to create a logical storage volume, bind, unbind, and rebind the logical storage volume, extend the size of the logical storage volume, clone the logical storage volume, and move the logical storage volume.

Abstract: A method is provided for recovering from an uncorrected memory error located at a memory address as identified by a memory device. A stored hash value for a memory page corresponding to the identified memory address is used to determine the correct data. Because the memory device specifies the location of the corrupted data, and the size of the window where the corruption occurred, the stored hash can be used to verify memory page reconstruction. With the known good part of the data in hand, the hashes of the pages using possible values in place of the corrupted data are calculated. It is expected that there will be a match between the previously stored hash and one of the computed hashes. As long as there is one and only one match, then that value, used in the place of the corrupted data, is the correct value. The corrupt data, once replaced, allows operation of the memory device to continue without needing to interrupt or otherwise affect a system's operation.

Abstract: One embodiment is a method for tracking data correspondences in a computer system including a host hardware platform, virtualization software running on the host hardware platform, and a virtual machine running on the virtualization software, the method including: (a) monitoring one or more data movement operations of the computer system; and (b) storing information regarding the one or more data movement operations in a data correspondence structure, which information provides a correspondence between data before one of the one or more data movement operations and data after the one of the one or more data movement operations. The “monitoring” may comprise monitoring data movement at one or more of an interface between the host hardware platform and the virtualization software, and an interface between the virtual machine and the virtualization software.

Abstract: Combining profiles based on priorities associated therewith to create an effective profile are provided. A plurality of profiles defining one or more rules that are applicable to a functional computing object are identified. A priority corresponding to each applicable profile is determined. The applicable profiles are combined by the computing device based on the corresponding priorities to create an effective profile that includes no conflicting rules.

Abstract: A server supporting the implementation of virtual machines includes a local memory used for caching. During I/O intensive processes, a “content aware” cache filter component of the server first accesses a cache structure in a content cache device to determine whether data blocks have been stored in the cache structure prior to requesting the data blocks from a networked disk array via a standard I/O stack of the hypervisor.

Abstract: Miss rate curves are constructed in a resource-efficient manner so that they can be constructed and memory management decisions can be made while the workloads are running. The resource-efficient technique includes the steps of selecting a subset of memory pages for the workload, maintaining a least recently used (LRU) data structure for the selected memory pages, detecting accesses to the selected memory pages and updating the LRU data structure in response to the detected accesses, and generating data for constructing a miss-rate curve for the workload using the LRU data structure. After a memory page is accessed, the memory page may be left untraced for a period of time, after which the memory page is retraced.

Abstract: Virtualization software can improve the effectiveness of a guest application running inside a virtual machine (VM) by providing information to the guest application indicative of a memory condition of the VM. The memory condition is indicative of an availability of memory resources to the guest application. When guest physical memory can be reserved by a balloon application running in the (VM), providing memory condition data indicative of the memory condition provides more accurate information regarding the availability of memory resources to the guest application than could be provided by the guest operating system of the VM.

Abstract: A server-based desktop-virtual machines architecture may be extended to a client machine. In one embodiment, a user desktop is remotely accessed from a client system. The remote desktop is generated by a first virtual machine running on a server system, which may comprise one or more server computers. During execution of the first virtual machine, writes to a corresponding virtual disk are directed to a delta disk file or redo log. A copy of the virtual disk is created on the client system. When a user decides to “check out” his or her desktop, the first virtual machine is terminated (if it is running) and a copy of the delta disk is created on the client system. Once the delta disk is present on the client system, a second virtual machine can be started on the client system using the virtual disk and delta disk to provide local access to the user's desktop at the client system. This allows the user to then access his or her desktop without being connected to a network.

Abstract: A method for transferring guest physical memory from a source host to a destination host during live migration of a virtual machine (VM) involves (a) transmitting pages of the guest physical memory from the source host to the destination host over a network connection, (b) transferring state information from the source host to the destination host, (c) while performance benefits regarding continued access to the guest physical memory on the source host persist, using the transferred state information to run the VM on the destination host in place of running the VM on the source host, and (d) while the VM is running on the destination host, writing pages of the guest physical memory from the source host to a shared datastore such that the destination host can retrieve the written guest physical pages from the shared datastore.

Abstract: The storage system exports logical storage volumes that are provisioned as storage objects. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. When traffic through a particular protocol endpoint is busy, the logical storage volume undergoes a rebind process pursuant to which the logical storage volume is bound to a new protocol endpoint, and the binding to the old protocol endpoint is removed upon completion of all pending input-output commands issued through the old protocol endpoint.

Abstract: The prioritization of large memory page mapping is a function of the access bits in the L1 page table. In a first phase of operation, the number of set access bits in each of the L1 page tables is counted periodically and a current count value is calculated therefrom. During the first phase, no pages are mapped large even if identified as such. After the first phase, the current count value is used to prioritize among potential large memory pages to determine which pages to map large. The system continues to calculate the current count value even after the first phase ends. When using hardware assist, the access bits in the nested page tables are used and when using software MMU, the access bits in the shadow page tables are used for large page prioritization.

A client is in communication with a server that is configured to separate an image into a plurality of regions. The server is also configured to determine a first data compression method for a first set of the regions and a second data compression method for a second set of the regions, wherein the second data compression method is different from the first data compression method. Further, the server is configured to compress the first set and the second set of the regions by using the first data compression method and the second data compression method, respectively. The server is also configured to transmit the first set and the second set of the regions that have been compressed to the client.

Abstract: Methods, techniques, and systems for dynamically allocating graphics processing units among virtual machines are provided. Example embodiments provide a dynamic GPU allocation system (“DGAS”), which enables the efficient allocation of physical GPU resources to one or more virtual machines. In one embodiment, the DGAS determines runtime profiles of a plurality of virtual machines. The runtime profiles are determined by determining a runtime assessment of workload indicative of a potential benefit that the virtual machine can receive from using a GPU resource. The DGAS then causes the processing bandwidth of the physical GPU resources to be allocated to some of the plurality of virtual machines based upon the dynamically determined runtime assessments of workload.
