摘要： A plurality of virtual machines (VMs) is established and maintained by virtualization software on one or more physical servers. Desktop management software operates to provide the VMs to remote users as virtualized desktops. The desktop management software includes a rule engine that can be used to automate the policies of the organization. The rule engine manages the data center by controlling virtual infrastructure operations, such as power-on, power-off, suspension, and migration operations. The rule engine uses an event-condition-action paradigm, wherein an event causes a virtual infrastructure operation, possibly contingent on a condition. The rule engine provides for time-based scheduling of events in addition to system-based operations, which are triggered by events such as user logon and user logoff. The rule engine may also include the ability to automate the process of changing the properties of the virtual machines in a timely fashion.

摘要： A plurality of virtual machines (VMs) is established and maintained by virtualization software on one or more physical servers. Desktop management software operates to provide the VMs to remote users as virtualized desktops. The desktop management software includes a connection broker, that allows a remote user to select a type of virtualized desktop and initiate a desktop session. The desktop management software further includes lease management functionality, that ensures users are provided access to a particular virtualized desktop for only a fixed period of time. In addition, the desktop management software provides an administrative console, which allows an administrator to set various parameters, including QoS parameters, and parameters specifying the resources allocated to each user. The desktop management software interacts with lower level software to provide load-balancing functionality, that adjusts the resources provided to each VM based on the needs of the VM. The load-balancing functionality also ensures that QoS parameters are met, and that the parameters specifying the maximum resources allocated to each user are not exceeded.

摘要： Completion interrupts corresponding to I/O requests issued by a virtual machine guest, which runs on a host platform, are virtualized in such a way that I/O completion interrupts to the requesting guest are delivered no faster than it can stably handle them, but, when possible, faster than the nominal speed of a virtual device to which a virtual machine addresses the I/O request. In general, completion events received from the host platform in response to guest I/O requests are examined with respect to time. If enough time has passed that the virtual device would normally have completed the I/O request, then the completion interrupt is delivered to the guest. If the nominal time has not elapsed, however, the invention enqueues and time-stamps the event and delivers it at the earliest of a) the normal maturity time, or b) at a safepoint.

摘要： A method is provided for optimizing a program by inserting memory prefetch operations in the program executing in a computer system. The computer system includes a processor and a memory. Latencies of instructions of the program are measured by hardware while the instructions are processed by a pipeline of the processor. Memory prefetch instructions are automatically inserted in the program based on the measured latencies to optimize execution of the program. The latencies measure the time from when a load instructions issues a request for data to the memory until the data are available in the processor. A program optimizer uses the measured latencies to estimate the number of cycles that elapse before data of a memory operation are available.
