Abstract: Described herein are systems and methods that manage machine backups, including the creation of virtual machine packages sufficient to instantiate virtual machines corresponding to the backups. In one aspect, a compute infrastructure includes many machines, which may be either physical or virtual. From time to time, snapshots of the states of these target machines are pulled and saved. Virtual machine packages corresponding to these snapshots are also created. A virtual machine package can be used to instantiate a virtual machine (VM) emulating the target machine with the saved state on a destination virtual machine platform. At some point, the initial VM package for a target machine is created by converting the snapshot to a VM package. However, this may take a long time. Later VM packages can instead be created by updating a prior VM package according to differences between the corresponding snapshots, rather than performing the full conversion process.

Abstract: Systems and methods for batching operations in a virtualization environment. A method embodiment operates over a plurality of virtual machines in the virtualization environment. A user interface is used to select two or more virtual machines that are to be subjected to the same batch actions. A method step then generates at least one batch request to be performed over the two or more selected virtual machines. In forming the batch request, the states of the individual virtual machines are analyzed to determine one or more entity-specific operations that apply to the virtual machines and/or to constituent entities of the virtual machines. Once the state-specific and entity-specific operations have been determined, an entity management protocol initiates execution of the one or more entity-specific operations over the individual ones of the two or more selected virtual machines.

Abstract: A system for virtual machine live migration includes a management node, a source server, a destination server, a peripheral component interconnect express (PCIe) switch, and an single root input/output virtualization (SR-IOV) network adapter, where the source server includes a virtual machine (VM) before live migration; the destination server includes a VM after live migration; the management node is adapted to configure, using the PCIe switch, a connection relationship between a virtual function (VF) module used by the VM before live migration and the source server as a connection relationship between the VF module and the destination server; and the destination server, using the PCIe switch and according to the connection relationship with the VF module configured by the management node, uses the VF module to complete virtual machine live migration. By switching the connection relationships, the system ensures that a data packet receiving and sending service is not interrupted.

Abstract: Technology is disclosed for establishing and administering multiple virtual machines, each with an audio, video and control (AVC) operating system (OS). The technology can also establish and administer cloud based AVC OSs. A server implementing this technology can perform real-time AVC processing, alongside soft and non-real-time processing and can host multiple, independent, virtual AVC OSs. Each AVC OS can perform the processing for an AVC setup. Each of the AVC OSs can be operated by a corresponding virtual machine controlled by a hypervisor running on the server. A cloud based AVC OS can perform processing for a corresponding remote AVC setup comprising multiple AVC devices. An AVC routing system can cause AVC signals from a particular AVC setup to reach a corresponding cloud AVC OS and conversely can cause signals from an AVC OS to reach the correct destination device.

Abstract: Systems and methods for scheduling, within a virtual machine, central processing unit time to be reserved for host machine execution of tasks are described. An example method may include execution, by a hypervisor running on a host computer system, a virtual machine comprising a virtual central processing unit. The virtual central processing unit is associated with a physical central processing unit of the host machine. The hypervisor determines a portion of central processing unit time to be reserved for host execution. The hypervisor notifies the virtual machine of the portion of central processing unit time that is reserved for host execution.

Abstract: A multi-processor system includes multiple processors arranged in multiple clusters. Different clusters have different power and performance characteristics. The system includes a task scheduler to schedule tasks to the processors. The task scheduler, in response to detection of a scheduling event trigger, is operative to identify a scheduling objective between a first objective of energy optimization and a second objective of load balance. The scheduling objective is identified based on at least respective operating frequencies and loading of all processors in a highest-capacity cluster of the multiple clusters. According to the identified scheduling objective, the task scheduler schedules a given task to a processor selected among the processors in the multiple clusters.

Abstract: A method is discussed for balancing processing loads to at least a first and a second VM instances associated with the same processing circuitry. Information about first and second applications respectively running on the first and second VM instances is obtained. Incoming data corresponding to a first and second pluralities of jobs to be performed respectively by the first and second VM instances is received. Based on the obtained information and on the received data, a first number of the first plurality of jobs which the first VM instance is allowed to perform is determined by means of the processing circuitry, and a second number of the second plurality of jobs which the second VM instance is allowed to perform is determined by means of the processing circuitry. The first VM instance is instructed to release the processing circuitry after having performed the determined first number of jobs to allow the second VM instance to use the processing circuitry for performing the second number of jobs.

Abstract: A time-aware method of scheduling application tasks in a green data center (GDC) using a task scheduling processor and an energy collecting processor connected to one or more renewable energy sources and a grid power source. The method includes receiving energy data regarding available energy from renewable energy resources such that the renewable energy source is used first then receiving the application tasks and determining a service rate for servers to process the application tasks by using a service rate obtained by solving a profit maximization problem for the GDC by prioritizing and immediately scheduling or removing certain application tasks. The method also includes determining an initial fitness level of each representative application task based on total revenue of the GDC, an energy cost of the GDC, and a penalty associated with violated constraints.

Abstract: Techniques for concurrent execution of multiple content item processes, such as video game processes, on a single virtual machine instance are described herein. In some examples, developers may provide an indication of a desired content item process quantity count, which is a quantity of content item processes for concurrent execution of content item sessions on each of one or more virtual machine instances. Also, in some examples, the content item process quantity count may be adjustable such that it may be changed, for example in response to various conditions or events. Also, in some cases, collected performance metric information may be used to make intelligent decisions regarding scaling of content item processes. In some examples, when a content item session stops executing on a healthy content item process, the content item process may remain active and may be reused by executing one or more subsequent content item sessions.

Abstract: A method and system for allocating and migrating workloads across an information technology (IT) environment based on persistent memory availability. Specifically, the method and system disclosed herein entail the intelligent placement of workloads on appropriate nodes of a node cluster based on workload requirements and node capabilities and/or resources availability. Further, workloads may be ranked based on a workload priority assigned to any particular workload, if available, or based on logged system calls issued by virtual machines hosting any particular workload. Subsequently, higher ranked workloads may be granted priority access to nodes that host healthier persistent memory, if any, or host higher performance traditional storage.
