Abstract: The subject matter described herein relates to offload technology. A source offload provider (520) may transfer bulk data to a destination offload provider (521) even if the offload providers are different and independent from each other and have no prior knowledge of each other. The data transfer is based on a token being exchanged that represents the bulk data. In preparation for transferring bulk data, trust between an initiator (505) of the transfer and the respective offload providers (520, 521) may be extended to the offload providers, i.e. the offload providers (520, 521) trust each other as they each trust the initiator (505). After authentication, the offload providers may transfer all or a portion of the bulk data over a secure channel (530) without the data traversing the initiator (505) of the transfer.
Abstract translation: 本文描述的主题涉及卸载技术。 即使卸载提供者彼此不同且彼此独立，并且彼此之间没有先验知识，源卸载提供者（520）也可以将批量数据传送到目的地卸载提供者（521）。 数据传输基于代表批量数据的被交换的令牌。 为了准备传输批量数据，传输的发起者（505）与相应的卸载提供者（520,521）之间的信任可以被扩展到卸载提供者，即卸载提供者（520,521）彼此信任，因为它们各自 信任发起者（505）。 在认证之后，卸载提供商可以通过安全信道（530）传输批量数据的全部或一部分，而数据遍历传输的发起者（505）。

Abstract: 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.

Abstract: Mechanisms are provided for the sharing of graphics adapter resources among multiple partitions in a virtual machine environment. A first mechanism allows for the sharing of graphics adapter resources so that one partition, a video service partition, containing a graphics proxy process, can use this graphics proxy process to offer graphics adapter resources to another partition, a video client partition. The graphics proxy process controls access time by any given partition to the graphics adapter resources. In one aspect, it uses a time bank to control access time, and the time bank controls how long a virtual graphics adapter offered to the video client partition can access the graphics adapter resources. A second mechanism synchronizes virtual memory in the video client partition to virtual memory in the video service partition. A third mechanism allows for multiple video client partition overlays using a pixel-shader-based virtual overlay mechanism.
Abstract translation: 提供了在虚拟机环境中在多个分区之间共享图形适配器资源的机制。 第一种机制允许共享图形适配器资源，使得包含图形代理进程的一个分区视频服务分区可以使用该图形代理进程向另一个分区（视频客户端分区）提供图形适配器资源。 图形代理过程控制任何给定分区到图形适配器资源的访问时间。 一方面，它使用时间库来控制访问时间，并且时间银行控制虚拟图形适配器提供给视频客户端分区的时间可以访问图形适配器资源。 第二种机制将视频客户端分区中的虚拟内存同步到视频服务分区中的虚拟内存。 第三种机制允许使用基于像素着色器的虚拟覆盖机制来实现多个视频客户端分区覆盖。

Abstract: Techniques for configuring a commodity server to host virtual hard disks are disclosed herein. In an exemplary embodiment, a virtual hard disk file can be split into a plurality of differencing VHD files and one or more of the files can be downloaded to a virtualization host as it runs off the VHD files stored on the server. After the one or more VHD files are downloaded, the virtualization host can be configured to use the local copy instead of the copy on the commodity server. In addition to the foregoing, other techniques are described in the claims, the detailed description, and the figures.

Abstract: Described is a technology by which a virtual hard disk is migrated from a source storage location to a target storage location without needing any shared physical storage, in which a machine may continue to use the virtual hard disk during migration. This facilitates use the virtual hard disk in conjunction with live-migrating a virtual machine. Virtual hard disk migration may occur fully before or after the virtual machine is migrated to the target host, or partially before and partially after virtual machine migration. Background copying, sending of write-through data, and/or servicing read requests may be used in the migration. Also described is throttling data writes and/or data communication to manage the migration of the virtual hard disk.

Abstract: Described is a technology by which a virtual hard disk is able to continue servicing virtual disk I/O (reads and writes) while a meta-operation (e.g., copying, moving, deleting, merging, compressing, defragmenting, cryptographic signing, lifting, dropping, converting, or compacting virtual disk data) is performed on the virtual disk. The servicing of virtual disk I/Os may be coordinated with meta- operation performance, such as by throttling and/or prioritizing the virtual disk I/Os. Also described is performing a meta-operation by manipulating one or more de-duplication data structures.

Abstract: Saving state of Random Access Memory (RAM) in use by guest operating system software is accomplished using state saving software that starts a plurality of compression threads for compressing RAM data blocks used by the guest. Each compression thread determines a compression level for a RAM data block based on a size of a queue of data to be written to disk, then compresses the RAM data block, and places the compressed block in the queue.

Abstract: Described are embodiments which allow token-based file operations. The client may request a special offload file operation that is formatted according to a file access protocol. The file operation may be an offload read operation or an offload write operation. In an offload read operation, the client requests that data be logically read from a stored file, or a portion thereof. In response, the file server provides a response that includes a token that represents the logically read data. In some embodiments, the file server may return a response with a token that represents less than all of the requested data if for some reason it cannot provide a token that represents all of the data. The token can then be used by the client in a subsequent offload write operation. In embodiments, the tokens represent immutable data that can be safely and securely used across servers and clients.

Abstract: In an exemplary embodiment, a virtual disk file can be assigned an identifier and a virtual disk files that is dependent on the virtual disk file can include a copy of the identifier. In the instance that the virtual disk file is opened and data is modified that causes the contents of a virtual disk extent to change the identifier can be changed. If the virtual disk file and the dependent virtual disk file are used to instantiate a virtual disk the difference between identifiers can be detected, which is indicative of the fact that the virtual disk may be corrupted. Other techniques are described in the detailed description, claims, and figures that form a part of this document.
