Abstract: An image of a virtualization software and firmware in a plurality of hosts are upgraded by performing the steps of: validating a desired image of the virtualization software by extracting dependencies and conflicts defined in metadata of all payloads of the desired image of the virtualization software, and confirming there are no violations of the extracted dependencies and conflicts; performing a pre-check of the desired image of the virtualization software against a current image of the virtualization software and a pre-check of the desired version of the firmware against a current version of the firmware; and upon determining from results of the pre-check that the virtualization software can be upgraded to the desired image and the firmware can be upgraded to the desired version, upgrading the current image of the virtualization software to the desired image and upgrading the current version of the firmware to the desired version.

Abstract: A desired image of a virtualization software is deployed in hosts that are located in a remote data center which is connected to a central data center over a first network having a lower bandwidth than that of a second network over which the hosts in the remote data center communicate with each other. The method of deploying the virtualization software in the hosts includes: upgrading the virtualization software in a first host of the plurality of hosts using portions of the desired image that are transmitted from the central data center to the remote data center over the first network; and upgrading the virtualization software in a second host of the plurality of hosts using portions of the desired image that are transmitted from the first host to the second host over the second network, without retransmitting the portions from the central data center to the remote data center.

Abstract: The disclosure provides a technique for reducing cache misses to a cache of a computer system. The technique includes deallocating memory pages of the cache from one process and allocating those memory pages to another process based on cache misses of each process during a given time period. Repeating the technique leads the total number of cache misses to the cache to gradually decrease to an optimum or near optimum level. The repetition of the technique leads to a dynamic and flexible apportionment of cache memory pages to processes running within the computer system.

Abstract: A method of probing a computer system includes steps of compiling a script that includes a call to a first function with first parameters, to generate executable code that includes a call to a second function with second parameters, wherein the second function and the second parameters are specified as values of the first parameters of the first function in the call to the first function, injecting the executable code into an executing module of the computer system, and as the executing module is running, executing the executable code to call the second function.

Abstract: A first hypervisor uses a first version of a virtual-memory file system (VMemFS) suspends virtual machines. A second hypervisor uses a instance of the VMemFS, the version of which may be the same or different from the first version. The VMemFS is designed so that an instance of the same or a later version of the VMemFS can read and ingest information in memory written to memory by another instance of the VMemFS. Accordingly, the second hypervisor resumes the virtual machines, effecting an update or other swap of hypervisors with minimal interruption. In other examples, the swapped hypervisors support process containers or simply support virtual memory.

Abstract: Techniques are disclosed for filtering input/output (I/O) requests in a virtualized computing environment. In some embodiments, a system stores first data in a page of memory, where after the first data is stored in the page of memory, the page of memory is free for allocation to a first memory consumer (e.g., an I/O filter instantiated in a virtualization layer of the virtualized computing environment) and a second memory consumer. The first memory consumer retains a reference to the page of memory. The first memory consumer receives a data request from a virtual computing instance. Based on the data request, the first memory consumer retrieves the first data using the reference to the page of memory. After retrieving the first data, the system returns the first data to the virtual computing instance. While the first memory consumer has the reference to the page of memory, the page of memory can be allocated to the second memory consumer without notifying the first memory consumer.

Abstract: Techniques for providing a cloud mobile device debugging service may be provided. For example, input may be received that is formatted in a particular debugging protocol. The input may be intended for execution on a browser of a mobile device that is remotely hosted with respect to the source of the input. The input may be translated from the particular debugging protocol to a common debugging protocol and provided to the remotely hosted mobile device. A result of executing the translated input with the remotely hosted mobile device may be displayed via a user interface.

Abstract: Techniques for providing a cloud mobile device-debugging server may be provided. For example, a request to initiate a communication channel with a mobile device may be received. The communication channel may be initiated based on the request and status information associated with the mobile device. Further, input may be received for interacting with the mobile device where the input corresponds to a particular input protocol. A proxy for translating and executing the received input may be selected based on the particular input protocol. A result of executing the input on the mobile device may be provided for display.

Abstract: The present technology provides a method, system and computer program product for managing the synchronization of a mobile electronic device, wherein management and adjustment of the synchronization process can be provided at least in part on a session by session basis. The synchronization process may be configurable via a user interface. Aspects of the user interface, such as prompts or degree of user configurability, may be adjusted depending on one or more factors, such as link effective speed or expected synchronization time.

Abstract: A method, apparatus and computer program product for data synchronization between a first file system and a second file system. File systems may be associated with handheld devices, memory devices, local or networked computer memory, or the like. Interaction with the first and second file systems follow first and second syntaxes, respectively. At least one file system is identified, for example based on a file path prefix thereof. One or more translation modules are selected based on the identification, each translation module configured to translate between a file system syntax and a generic syntax. Appropriate aspects of a set of operations for performing the data synchronization are translated using appropriate translation modules.
