    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: This document describes techniques for effecting a virtual disk. In an exemplary configuration, a virtual disk file can be associated with a log that acts as both a log and a check point record. When a log entry is generated, information that identifies the tail can be stored therein. This information can be used in the event that virtual disk file is improperly closed, i.e., a crash or power failure occurs, to discover a sequence of log entries to replay. In addition to the foregoing, other techniques are described in the claims, detailed description, and figures.

    摘要: A network stack sends very large packets with large segment offload (LSO) by performing multi-pass LSO. A first-stage LSO filter is inserted between the network stack and the physical NIC. The first-stage filter splits very large LSO packets into LSO packets that are small enough for the NIC. The NIC then performs a second pass of LSO by splitting these sub-packets into standard MTU-sized networking packets for transmission on the network.
