A system and method for providing dynamic information virtualization (DIV) is disclosed. According to one embodiment, a device includes a dynamic optimization manager (DOM), a process and memory manager (PMM), a memory, and a host device driver. The device starts virtual functions after booting to allow a virtual machine (VM) running a guest operating system to identify the virtual functions and load virtual drivers of the virtual functions. The PMM allocates a unified cache from the memory to facilitate coherent access to information from storage and network resources by the VM. The host device driver enables a guest process in the VM to access the information stored in the unified cache in a secure and isolated manner.

Some embodiments provide a method for extracting and adapting system configuration. The method extracts a first configuration from a first node of a first hosting system. The first node includes several resources for hosting the first configuration. The method analyzes the first configuration in order to determine attributes of the first configuration. The determined attributes are relevant to hosting the first configuration on a second node of a second hosting system having several nodes. The method generates a second configuration based on the determined attributes. The method hosts the second configuration at the second node of the second hosting system.

Systems and methods are provided for modifying a set of memory pages. An example method includes loading kernel code and patching code of a kernel into a guest memory. The patching code is stored at a first range of memory addresses, which is in an executable mode in a first set of hypervisor page tables. The method also includes detecting a demand to modify a set of memory pages and sending a request to the hypervisor to transfer control to the patching code in response to detecting the demand. The hypervisor may switch from the first set of hypervisor page tables to a second set of hypervisor page tables in response to detecting a request to transfer control to the patching code. The set of memory pages is write-protected in the second set of hypervisor page tables, and is writable in the first set of hypervisor page tables.

A method for fetching a content from a web server to a client device is disclosed, using tunnel devices serving as intermediate devices. The tunnel device is selected based on an attribute, such as IP Geolocation. A tunnel bank server stores a list of available tunnels that may be used, associated with values of various attribute types. The tunnel devices initiate communication with the tunnel bank server, and stays connected to it, for allowing a communication session initiated by the tunnel bank server. Upon receiving a request from a client to a content and for specific attribute types and values, a tunnel is selected by the tunnel bank server, and is used as a tunnel for retrieving the required content from the web server, using standard protocol such as SOCKS, WebSocket or HTTP Proxy. The client only communicates with a super proxy server that manages the content fetching scheme.

A processing core comprising instruction execution logic circuitry and register space. The register space to be loaded from a VMCS, commensurate with a VM entry, with information indicating whether a service provided by the processing core on behalf of the VMM is enabled. The instruction execution logic to, in response to guest software invoking an instruction: refer to the register space to confirm that the service has been enabled, and, refer to second register space or memory space to fetch input parameters for said service written by said guest software.

There is provided a method for coordinated scheduling between real-time processes. The method is performed by a central scheduler. The method comprises acquiring information on runtimes and deadlines for real-time processes of tasks for local schedulers to be executed on shared computing resources. The method comprises scheduling the real-time processes based on the runtimes and deadlines so as to keep the deadlines during execution of the real-time processes. There is also provided a central scheduler configured to perform such a method. There is also provided a computer program comprising computer program code which, when run on a processing unit of a central scheduler causes the processing unit to execute such a method.

Some embodiments provide a method for extracting and adapting system configuration. The method extracts a first configuration from a first node of a first hosting system. The first node includes several resources for hosting the first configuration. The method analyzes the first configuration in order to determine attributes of the first configuration. The determined attributes are relevant to hosting the first configuration on a second node of a second hosting system having several nodes. The method generates a second configuration based on the determined attributes. The method hosts the second configuration at the second node of the second hosting system.

A scheduling method for virtual processors based on the affinity of NUMA high-performance network buffer resources, including: in a NUMA architecture, when a network interface card (NIC) of a virtual machine is started, getting distribution of the buffer of the NIC on each NUMA node; getting affinities of each NUMA node for the buffer of the network interface card on the basis of an affinity relationship between each NUMA node; determining a target NUMA node in combination with the distribution of the buffer of the NIC on each NUMA node and NUMA node affinities for the buffer of the NIC; scheduling the virtual processor to the CPU on the target NUMA node. The problem of affinity between the VCPU of the virtual machine and the buffer of the NIC not being optimal in the NUMA architecture is solved to reduce the speed of VCPU processing network packets.

A method and system for the scheduled capturing of web content from a web server includes a capturing server establishing a link with a client device and receiving over the link from the client device a set of indications for web content to capture and schedule information for capturing the web content. The method further includes performing, in accordance with the schedule information, establishing a network connection with the web server hosting a web resource of the indicated web content, receiving the web resource over the network connection from the web server without the web resource being routed through the client device, and capturing the web resource as a set of images of the web resource loaded into a web browser executing on the capturing server.

A method including running a virtualization layer on a processor, the virtualization layer being adapted to assign processor time and memory to first and second guest operating systems running on the virtualization layer, wherein the first guest operating system is a real time operating system, obtaining, by the second guest system, information to be displayed on a display, preparing, by the second guest system, a display frame to be sent to the display, reading, by the first guest system, a portion of the display frame, or retrieving, by the first guest system, information about a read portion of the display frame, and determining, by the first guest system, whether the information sent to the second guest system is correctly generated in the display frame.
