20150039838 | METHOD AND SYSTEM FOR RESTORING CONSUMED MEMORY AFTER MEMORY CONSOLIDATION - One embodiment of the system disclosed herein facilitates reduction of latency associated with accessing content of a memory page that has been swapped out by a guest operating system in a virtualized computer system. During operation, a hypervisor detects an I/O write command issued by the guest operating system at a swap location within the guest operating system's swap file and records the swap location. The hypervisor then prefetches contents of a page stored at the swap location within the guest operating system's swap file into a prefetch cache in host machine memory. Subsequently, the hypervisor detects an I/O read command issued by the guest operating system at the swap location within the swap file. In response, the hypervisor provides contents of the page to the guest operating system from the prefetch cache, thereby avoiding accessing the guest operating system's swap file. | 02-05-2015 |
20150109329 | AUGMENTING A PHYSICAL DEVICE WITH VIRTUAL INFORMATION - In a computer-implemented method for augmenting at least one physical device with virtual information indicia corresponding to the at least on physical device supporting a virtualization infrastructure is observed. Based on the observed indicia, virtual information of said virtualization infrastructure correlating to the at least one physical device is displayed. | 04-23-2015 |
20150109334 | AUGMENTED REALITY AIDED NAVIGATION - In a computer-implemented method for augmented reality aided navigation to at least one physical device indicia corresponding to the at least one physical device supporting virtualization infrastructure is observed. Based on the observed indicia, navigational cues correlating to a location of the at least one physical device is generated. Navigational cues are displayed such that augmented reality aided navigation is provided to the at least one physical device. | 04-23-2015 |
20150149999 | VIRTUAL MACHINE GROUP MIGRATION - A plurality of virtual machines (VMs) is migrated from a source group to a destination group in such as way as to achieve consistency and either availability or group preservation. Execution of VMs in the source group is selectively delayed during state migration so that memory transfer of all the VMs in the group will converge roughly at the same time. After VM state transfer to the destination group, execution switch-over is coordinated using different handshake and acknowledgement messages, passed either through a “leader” VM in each group, or directly between source-destination VM pairs. | 05-28-2015 |
20150178107 | Elastic Compute Fabric Using Virtual Machine Templates - Embodiments include an infrastructure shared among cloud services that supports fast provisioning of virtual machines (VMs). A set of powered-on parent VM templates and a set of powered-off child VMs are maintained by the infrastructure in a hierarchy. The child VMs are instantiated from the parent VM templates, and pre-registered to a cloud operating system in some embodiments. In response to requests from the cloud services for the child VMs, where the requests specify child VM configurations, child VMs from the set of powered-off child VMs are selected and customized based on the child VM configurations, and then deployed for use by the cloud services. In some embodiments, the fast provisioning of VMs is supported by forking operations in the infrastructure. | 06-25-2015 |
20150178108 | Fast Instantiation of Virtual Machines - Embodiments support instant forking of virtual machines (VMs) and state customization. Virtual device state and persistent storage of a child VM are defined based on virtual device state and persistent storage of parent VMs. After forking, a state of the child VM is customized based on configuration data. Customizing the state includes configuring one or more identities of the child VM, before bootup completes on the child VM. | 06-25-2015 |
20150178110 | State Customization of Forked Virtual Machines - Embodiments support instant forking of virtual machines (VMs) and state customization. A computing device initiates execution of a first group of services (e.g., identity-independent) in a first VM. A second VM is instantiated from the first VM. The second VM shares memory and storage with the first VM. The computing device customizes the second VM based on configuration data associated with the second VM. A second group of services (e.g., identity-dependent) starts executing on the second VM after configuring the identity of the second VM. Customizing the second VM includes configuring one or more identities of the second VM. In some embodiments, a domain identity is selected from a pool of previously-created identities and applied to the second VM, before bootup completes on the second VM. | 06-25-2015 |
20150301931 | METHOD OF ALLOCATING REFERENCED MEMORY PAGES FROM A FREE LIST - Memory pages that are allocated to a memory consumer and continue to be accessed by the memory consumer are included in a free list, so that they may be immediately allocated to another memory consumer as needed during the course of normal operation without preserving the original contents of the memory page. When a memory page in the free list is accessed to perform a read, a generation number associated with the memory page is compared with a stored copy. If the two match, the read is performed on the memory page. If the two do not match, the read is not performed on the memory page. | 10-22-2015 |
