摘要： In a multiprocessing computer system, a schedulable process entity (such as a UNIX process, a Solaris lightweight process, or a Windows NT thread) sets a memory flag (sc.sub.-- nopreempt) before acquiring a shared resource. This flag tells the operating system that the process entity should not be preempted. When it is time for the process entity to be preempted, but sc.sub.-- nopreempt is set, the operating system sets a flag (sc.sub.-- yield) to tell the process entity that the entity should surrender the CPU when the entity releases the shared resource. However, the entity is not preempted but continues to run. When the entity releases the shared resource, the entity checks the sc.sub.-- yield flag. If the flag is set, the entity makes an OS call to surrender the CPU.
摘要翻译：在多处理计算机系统中，可调度的进程实体（例如UNIX进程，Solaris轻量进程或Windows NT线程）在获取共享资源之前设置内存标志（sc-nopreempt）。该标志告诉操作系统，流程实体不应被抢占。当流程实体被抢占时，但设置sc-nopreempt时，操作系统设置一个标志（sc-yield）来告知进程实体实体释放共享资源时该实体应该放弃CPU。但是，该实体不被抢占，而是继续运行。当实体释放共享资源时，实体检查sc-yield标志。如果标志被设置，则实体进行OS调用以投降CPU。

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： One or more techniques and/or systems are provided for non-disruptively addressing misalignment between a virtual data format and an underlying data format. Virtual data, such as a guest operating system of a virtual machine, may be stored within a virtual structure, such as a virtual machine disk, according to a virtual data format. The virtual structure may be stored within a storage device according to a storage data format. If misalignment is detected, then a new data container may be created within the storage device. A shim, sized according to a misalignment offset, may be inserted into the new data container in order to align the new data container with the storage device. Virtual data may be migrated from the virtual structure to the new data container to achieve alignment. During the migration, the virtual data may remain available from the virtual structure (e.g., a virtual machine may still execute).

摘要： Techniques for creating a fault tolerant system in a virtual machine environment utilize a primary VM and a backup VM. To initialize the fault tolerant system, the backup VM and primary VM start from the same state. To achieve this in one embodiment, the primary VM is suspended and the state of the primary VM is copied to the backup VM. Once the backup VM has received all the primary VM's state, the primary VM is resumed. Subsequent state changes of the primary VM are buffered until the backup VM resumes, connects to the primary VM, and starts consuming the buffered content. Thereafter, synchronization is maintained by the primary VM's writing relevant state changes to a log and the backup VM's reading such relevant state changes from the log.

摘要： A fault-tolerant virtualized computer system comprises a primary host executing a primary virtual machine (VM) and a backup host executing a backup VM. In one embodiment, each VM includes a virtual disk mapped to a shared disk image on physical disk accessible to both hosts. A virtual disk IO request is received by virtualization software executing on the backup host from a backup VM. When the virtual disk IO request is a read request, the virtual disk IO request is mapped to a physical read IO request of a virtual disk image stored on a physical disk, the physical read IO request is issued to the physical disk. However, when the virtual disk IO request is a write request, it is assumed to be completed without mapping the virtual disk IO request or issuing a mapped physical IO request to the physical disk.
