Method and system for managing execution of virtual applications

Номер: US20120005246A1

Автор: Kenji C. Obata

Принадлежит: Code Systems Corp

A system and method for directing download and execution of an application. A runtime engine receives an identifier of a block of shared memory from a directing process. The shared memory stores a map indicating which portions of an application file have been stored in a local copy of the application file. The runtime engine also receives an instruction from the directing process to execute the local copy when the local copy stores less than the entire application file. As the application executes, the runtime engine identifies requests from the application to access portions of the local copy and uses the map to determine whether the requested portions have been stored in the local copy. If the requested portions are not stored in the local copy, the runtime engine prevents the executing application from accessing the local copy until the map indicates the requested portions have been stored therein.

The machine instruction can include an instruction opcode, a source address referring to a first type of memory and a destination address referring to a second type of memory. A register bitmap can be stored as a register-level memory-mode flag array. Thereafter, it can be determined whether or not the instruction opcode maps to an inheritance class. Finally, in response to a bit in the register-level memory mode flag array referencing virtual memory and the instruction opcode being mapped to an inheritance class, the register bitmap can be replaced with new bit values that represent redefined memory types for each register represented in the register bitmap. Subsequently, the new register bitmap can be used in simulation of a next machine instruction of a live memory analysis command executing in the virtual machine.

A heterogeneous processing system is described herein that provides a software hypervisor to autonomously control operating system thread scheduling across big and little cores without the operating system's awareness or involvement to improve energy efficiency or meet other processing goals. The system presents a finite set of virtualized compute cores to the operating system to which the system schedules threads for execution. Subsequently, the hypervisor intelligently controls the physical assignment and selection of which core(s) execute each thread to manage energy use or other processing requirements. By using a software hypervisor to abstract the underlying big and little computer architecture, the performance and power operating differences between the cores remain opaque to the operating system. The inherent indirection also decouples the release of hardware with new capabilities from the operating system release schedule.

Controlling network utilization

Номер: US20130007254A1

Автор: Robert Fries

Принадлежит: Microsoft Corp

Network utilization of an arbitrary application is controlled by tracking network usage statistics of virtual machines (VMs), including at least VMs hosting parts of the application. For network utilization control, VMs serve as network proxies for elements of the application. A specification for a network requirement of the application is evaluated against the network usage statistics. When a network capacity requirement to/from/through an element of the application is not satisfied, one or more VMs are adapted to satisfy the requirement. For example, a VM may be migrated from a host or network location that has excess network bandwidth. Or, for example, network bandwidth availability for an under-requirement VM may be increased and bandwidth availability for a VM at an appropriate host or network location may be decreased. Thus, application-level communication path requirements may be satisfied using VM adaptations.

Номер: US20130014101A1

Автор: Antony Rowstron, Hitesh Ballani, Paolo Costa, Thomas Karagiannis

Принадлежит: Microsoft Corp

Methods of offering network performance guarantees in multi-tenant datacenters are described. In an embodiment, a request for resources received at a datacenter from a tenant comprises a number of virtual machines and a performance requirement, such as a bandwidth requirement, specified by the tenant. A network manager within the datacenter maps the request onto the datacenter topology and allocates virtual machines within the datacenter based on the available slots for virtual machines within the topology and such that the performance requirement is satisfied. Following allocation, stored residual capacity values for elements within the topology are updated according to the new allocation and this updated stored data is used in mapping subsequent requests onto the datacenter. The allocated virtual machines form part of a virtual network within the datacenter which is allocated in response to the request and two virtual network abstractions are described: virtual clusters and virtual oversubscribed clusters.

On-Line Replacement and Changing of Virtualization Software

Номер: US20130024862A1

Автор: Beng-Hong Lim, Kinshuk Govil

Принадлежит: VMware LLC

In a virtualized system running one or more virtual machines on a first hypervisor, a second hypervisor is installed and control of the hardware resources of the physical computer supporting the virtualized system is migrated from the first hypervisor to the second hypervisor without interrupting the operation of the first hypervisor and the virtual machines. Initially a minimal set of hardware resources is hot-removed from control by the first hypervisor, and the second hypervisor is launched on the minimal set of hardware resources. Both the remaining hardware resources and the virtual machines are then migrated from the first hypervisor to the second hypervisor until all the virtual machines have been migrated over to the second hypervisor, while the virtual machines and the first hypervisor continue running largely unaffected by the migration process.

In a cloud computing environment, a production server virtualization stack is minimized to present fewer security vulnerabilities to malicious software running within a guest virtual machine. The minimal virtualization stack includes support for those virtual devices necessary for the operation of a guest operating system, with the code base of those virtual devices further reduced. Further, a dedicated, isolated boot server provides functionality to securely boot a guest operating system. The boot server is isolated through use of an attestation protocol, by which the boot server presents a secret to a network switch to attest that the boot server is operating in a clean mode. The attestation protocol may further employ a secure co-processor to seal the secret, so that it is only accessible when the boot server is operating in the clean mode.

Multiple machine state registers are included in a processor core to permit distinction between use of hardware facilities by applications, supervisory threads and the hypervisor. All facilities are initially disabled by the hypervisor when a partition is initialized. When any access is made to a disabled facility, the hypervisor receives an indication of which facility was accessed and sets a corresponding hardware flag in the hypervisor's machine state register. When an application attempts to access a disabled facility, the supervisor managing the operating system image receives an indication of which facility was accessed and sets a corresponding hardware flag in the supervisor's machine state register. The multiple register implementation permits the supervisor to determine whether particular hardware facilities need to have their state saved when an application context swap occurs and the hypervisor can determine which hardware facilities need to have their state saved when a partition swap occurs.
