Abstract: Examples maintain consistency of writes for a plurality of VMs during live migration of the plurality from a source host to a destination host. The disclosure intercepts I/O writes to a migrated VM at a destination host and mirrors the I/O writes back to the source host. This “reverse replication” ensures that the CG of the source host is up to date, and that the source host is safe to fail back to if the migration fails.

Abstract: The current application is directed to architected hardware support within computer processors for detecting and monitoring various types of potential performance imbalances with respect to simultaneously executing hardware threads in simultaneous multi-threading (“SMT”) processors and SMT-processor cores. The architected hardware support may include various types of performance-imbalance-monitoring registers that accumulate indications of performance imbalances and that can be used, by performance-monitoring software and by human analysts to detect performance-degrading conflicts between simultaneously executing hardware threads. Such conflicts can be ameliorated by changing the scheduling of virtual machines, tasks, and other computational entities, by redesigning and re-implementing all or portions of performance-limited and performance-degrading applications, by altering resource-allocation strategies, and by other means. In addition, performance imbalance detection and monitoring can be used to provide accurate, computational-throughput-based accounting in cloud-computing environments.

Abstract: A virtual-machine-based system provides a mechanism to implement application file I/O operations of protected data by implementing the I/O operations semantics in a shim layer with memory-mapped regions. The semantics of these I/O operations are emulated in a shim layer with memory-mapped regions by using a mapping between a process' address space and a file or shared memory object. Data that is protected from viewing by a guest OS running in a virtual machine may nonetheless be accessed by the process.

Abstract: A method for providing real time replication status for a networked virtualization environment for storage management, includes scanning metadata to identify replication status for all virtual disks (vDisks) in the networked virtualization environment, generating replication tasks for vDisks that are identified as under replicated based on the scan, performing the replication tasks, monitoring the progress of the replication tasks and determining the real time replication status of the networked virtualization environment based on the scanned metadata and the monitored progress of the replication tasks.

Abstract: The data storage system according to certain aspects can manage the archiving of virtual machines to (and restoring of virtual machines from) secondary storage. The system may archive virtual machines (VMs) that are determined to have a low level of utilization. The system may create a virtual machine placeholder for an archived VM, which may be a “light” or minimal version of the VM that acts like the actual VM. By using a VM placeholder, a VM may appear to be active and selectable by the user. When the user selects the VM, the VM placeholder can interact with the user in similar manner as the VM. Accessing the VM placeholder may trigger restore of the archived VM from secondary storage. The restore of the archived VM may be “seamless” to the user since the VM remains available while it is being restored.

Abstract: A computer-implemented method for protecting virtual machine data may include (1) receiving a request to perform a granular backup operation on data stored by a guest system within a virtual machine, (2) identifying a storage container that comprises an agent that performs backup operations, (3) attaching the storage container to the virtual machine in response to the request, and (4) performing the granular backup operation by sending an instruction to the guest system within the virtual machine to execute the agent. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: According to one aspect of the present invention there is provided a system, method, and computer program product for recovering from a network failure in a communication network using network function virtualization (NFV-based network), the method including: selecting a first network component of the NFV-based network, detecting at least one probable failure of the first network component, identifying at least one virtual network function (VNF) instance using the first network component, selecting a second network component to be used by same VNF for replacing the VNF instance in the first network component when the first network component is faulty, and securing at least one resource of the second network component for the VNF.
