Abstract:
Embodiments disclosed herein are related to systems, methods, and computer readable medium for allocating one or more system resources for the exclusive use of an application. The embodiments include receiving a request for an exclusive allocation of one or more system resources for a first application, the one or more system resources being useable by the first application and one or more second applications; determining an appropriate amount of the one or more system resources that are to be allocated exclusively to the first application; and partitioning the one or more system resources into a first portion that is allocated for the exclusive use of the first application and a second portion that is not allocated for the exclusive use of the first application, the second portion being available for the use of the one or more second applications.
Abstract:
A computing system includes a parent partition, child partitions, a hypervisor, shared memories each associated with one of the child partitions, and trigger pages each associated with one of the child partitions. The hypervisor receives a system event signal from one of the child partitions and, in response to receiving the system event signal, accesses the trigger page associated with that child partition. The hypervisor determines whether the trigger page indicates whether data is available to be read from the shared memory associated with the child partition. The hypervisor can send an indication to either the parent partition or the child partitions that data is available to be read from the shared memory associated with the child partition if the hypervisor determines that the trigger page indicates that data is available to be read from the shared memory associated with the child partition.
Abstract:
A user can select a capacity setting for a transitional partition that determines the allocation between a low-density partition and a high-density partition in the transitional partition. The transitional partition can dynamically change among multiple settings having different capacities for the low-density partition. If the current setting of the transitional partition does not efficiently utilize the available storage space based on the user's preferences for storing different types of data in the low-density partition and the high-density partition, then the user can choose to change the transitional partition to a different setting that better suits the individual user's storage allocation preferences. Therefore, valuable storage space will not be under-utilized but instead will be repurposed for more efficient use by converting a low-density partition to a high-density partition, and vice versa.
Abstract:
The present disclosure relates to devices, methods, and computer-readable medium for saving and restoring physical hardware states and virtual machine (VM) states for an application actively being executed on a virtual machine by a user on a computer device. The devices, methods, and computer-readable medium may allow a user to suspend a current state of an application session and save the VM and memory state to persistent storage, and later resume the execution of the saved application session by reading the state back into memory and restoring the VM state.

Abstract:
Idle virtual machine partitions in a virtualized computing environment are consolidated onto one or more idle logical processors. A hypervisor monitors the individual utilization of multiple virtual machine partitions in a computing environment and determines which virtual machine partitions are idle. The hypervisor also monitors the individual utilization of multiple logical processors in the computing environment and determines which logical processors are idle. The hypervisor schedules all of the idle virtual machine partitions on one or more of the idle logical processors. This can improve the performance for work-generating partitions and ensure compliance with service level agreements. At the same time, it can provide efficient power management in that is consolidates idle virtual machines onto a smaller subset of logical processors.

Abstract:
Various aspects are disclosed herein for attenuating spin waiting in a virtual machine environment comprising a plurality of virtual machines and virtual processors. Selected virtual processors can be given time slice extensions in order to prevent such virtual processors from becoming de-scheduled (and hence causing other virtual processors to have to spin wait). Selected virtual processors can also be expressly scheduled so that they can be given higher priority to resources, resulting in reduced spin waits for other virtual processors waiting on such selected virtual processors. Finally, various spin wait detection techniques can be incorporated into the time slice extension and express scheduling mechanisms, in order to identify potential and existing spin waiting scenarios.
