摘要： A method and system for offloading a software application intended to be run on a first virtual machine onto a second virtual machine. An original virtual machine is created. A periodic and/or computing resource-intensive application is supposed to be run on the original virtual machine. However, doing so may detrimentally impact the operation of the original virtual machine by consuming valuable computing resources. A replicated virtual machine which is basically a copy of the original virtual machine is created and ported over to a different host computer system. The periodic and/or computing-intensive application is now run on the replicated virtual machine instead of the original virtual machine. This leaves the original virtual machine free to continue its normal operations unaffected.
摘要翻译：一种用于将要在第一虚拟机上运行的软件应用程序卸载到第二虚拟机上的方法和系统。创建一个原始的虚拟机。假定在原始虚拟机上运行周期性和/或计算资源密集型应用程序。然而，这样做可能通过消耗有价值的计算资源而不利地影响原始虚拟机的操作。基本上是原始虚拟机的副本的复制虚拟机被创建并移植到不同的主机系统。周期性和/或计算密集型应用程序现在在复制的虚拟机而不是原始虚拟机上运行。这使得原始虚拟机可以自由地继续其正常操作而不受影响。

摘要： A method and system for acquiring a quiesceing set of information associated with a virtual machine. A virtual machine is cloned. The cloned virtual machine has an associated persistent storage device. The state of the persistent storage device is transformed into a quiesced state of the cloned virtual machine by utilizing a shut-down process. The shut-down process is executed on the cloned virtual machine to quiesce the cloned virtual machine and the quiesceing set of information of the cloned virtual machine is automatically reduced to information stored on the persistent storage device.

摘要： An architecture and system are described that provide a unified file access service within in a managed computing environment composed of diverse networks, computing devices, and storage devices. The service provides mechanisms for remotely accessing the file systems of any managed computer or disk snapshot, independently of the computer's current state (powered on, suspended or powered off), its location within the environment, its hardware type (virtual vs. physical), its operating system type, and its file system formats. The system isolates centralized FPAs from the details of clients, proxies and storage elements by providing a service that decomposes offloaded file system access into two steps. A FPA or a requester acting on behalf of the FPA first expresses the disk set or the computer containing the file systems it wishes to access, along with requirements and preferences about the access method. The service figures out an efficient data path satisfying the FPA's needs, and then automatically configures a set of storage and computing resources to provide the data path. The service then replies with information about the resources and instructions for using them. The FPA then accesses the requested file systems using the returned information.

摘要： A process of providing access to data associated with a virtual machine running on a host computer system to an offload server is implemented to improve the performance of the host computer system. Once the offload computer system knows how and where to access the data associated with that of the virtual machine, operations can be offloaded from the host computer system and performed by the offload server. Backup operations can be offloaded onto the server. The server can run backup software and directly access the data associated with the virtual machine, thereby freeing the hardware resources of the host computer to handle normal applications running on the virtual machine.

摘要： Systems and methods for tracking changes and performing backups to a storage device are provided. For virtual disks of a virtual machine, changes are tracked from outside the virtual machine in the kernel of a virtualization layer. The changes can be tracked in a lightweight fashion with a bitmap, with a finer granularity stored and tracked at intermittent intervals in persistent storage. Multiple backup applications can be allowed to accurately and efficiently backup a storage device. Each backup application can determine which block of the storage device has been updated since the last backup of a respective application. This change log is efficiently stored as a counter value for each block, where the counter is incremented when a backup is performed. The change log can be maintained with little impact on I/O by using a coarse bitmap to update the finer grained change log.

摘要： Computer implemented methods, computer program products and computer systems synchronize copies of a virtual disk. A record of blocks that are modified during an access session of a copy of the virtual disk is maintained. For each partition of the virtual disk, a file system level indication of currently relevant blocks is obtained. Only those blocks that were modified during the access session and are currently relevant are copied to at least one additional copy of the virtual disk.
