摘要： Embodiments are directed to establishing efficient virtual machine reference points and to specifying a virtual machine reference point to query incremental changes. In one scenario, a computer system accesses a stable virtual machine checkpoint that includes portions of underlying data stored in data storage, where the checkpoint is associated with a specific point in time. The computer system then queries the data storage to determine data storage identifiers that reference the point in time associated with the checkpoint and stores the determined data storage identifiers as a virtual machine reference point, where each subsequent change to the data storage results in an update to the data storage identifier, so that virtual machine reference point is usable to identify incremental changes from specific points in time on.

摘要： A host operating system running on a computing device monitors network communications for the computing device to identify network resources that are requested by the computing device. The host operating system compares requested network resources against security policies to determine if the requested network resources are trusted. When an untrusted network resource is identified, the host operating system accesses the untrusted network resource within a container that is isolated from the host operating system kernel using techniques discussed herein. By restricting access to untrusted network resources to isolated containers, the host operating system is protected from even kernel-level attacks or infections that may result from an untrusted network resource.

摘要： Embodiments provide a method and system for transferring data between different computing devices. Specifically, a communication session is established between a first computing device and a second computing device. The communication session may be established using a first communication protocol. The first computing device creates a virtual memory object which is bound to one or more memory blocks of the first computing device. A path to the virtual memory object is generated and the path is transmitted to the second computing device using the communication session. The second computing device may then read or write data directly into/from the virtual memory object using a second communication protocol that is different from the first communication protocol. The data is written into and read from the virtual memory object using file system commands.

摘要： Techniques for migrating a virtual machine from a source computer system to a target computer system are disclosed. In an exemplary embodiment, a group of pages can be mapped writable in response to determining that the guest operating system attempted to change a specific page. In the same, or other embodiments, pages can be compressed prior to sending such that throughput of a communication channel is maximized. In the same, or other embodiments, storage IO jobs can be canceled on a source computer system and reissued by a target computer system.

摘要： Embodiments are directed to backing up a virtual machine cluster and to determining virtual machine node ownership prior to backing up a virtual machine cluster. In one scenario, a computer system determines which virtual machines nodes are part of the virtual machine cluster, determines which shared storage resources are part of the virtual machine cluster and determines which virtual machine nodes own the shared storage resources. The computer system then indicates to the virtual machine node owners that at least one specified application is to be quiesced over the nodes of the virtual machine cluster, such that a consistent, cluster-wide checkpoint can be created. The computer system further creates a cluster-wide checkpoint which includes a checkpoint for each virtual machine in the virtual machine cluster.
