Abstract: A method for generation of virtual images on a computer system having a Virtual Machine (VM), including (a) generating a virtual image of the VM that includes a state of the VM's disk at a particular moment in time; wherein the virtual image is viewable via a host-side graphical representation component for viewing a history of virtual images representing states of the VM's disk at prior moments in time; (b) storing the virtual image as multiple chunks or partitions; (c) from the host side, acquiring a state of the VM's memory and adding the state of the VM's memory to the virtual image; (d) configuring the graphical representation component to display only selected virtual images based on user selection, and (e) in the graphical representation component, displaying a representation of differences between at least two of the virtual images.

Abstract: The invention relates to a computer-implemented method for updating an operating system (OS) without a memory reset. The method includes launching a Virtual Execution Environment (VEE) under a host OS of a computer system. The VEE can be a VM or a Container. Next, a snapshot of the VEE is generated, including snapshotting user process data, of any processes that run under the VEE. A new OS is loaded onto the computer system, and control is given to the new OS without performing the memory reset. It is ensured that the user process data that is part of the snapshot is unaffected by the loading of the new OS and that the user process data remains in its original location. The VEE is re-launched under the new OS. User process data is restored from the snapshot into a random access memory.

Abstract: A system and method for managing licensing of virtual environment applications. A licensing module of a first installed virtual environment application detects installation of affiliated applications and gives them a group licensing key for passing it to the licensing server. The licensing server derives licensing parameters of the affiliated applications from the group key and gives the licenses to the affiliated applications, in case of successful validation. The licensing system provides protection from un-authorized copying of the applications. If an affiliated virtual environment application is copied (or moved) to another hardware node without its virtual environment, the licensing server will not give the license activation key to this virtual environment application.

Abstract: Method for avoiding Guest I/O timeout, including generating a request to an I/O device in a Guest Operating System (GOS) running inside a VM; setting a VM timeout deadline; in a hypervisor, setting a supervisory timeout deadline for the I/O device to respond that is shorter than the VM timeout deadline; if no response is received before expiration of the supervisory timeout deadline, pausing the GOS; freezing system time of the GOS; activating a handler for the I/O device response in the hypervisor; upon receipt of the response prior to the supervisory timeout deadline, forwarding the response to the GOS, unpausing the GOS, unfreezing the system time of the GOS; upon receipt of the response after the supervisory timeout deadline, and after the GOS is unpaused by the hypervisor, the Guest OS receives the response from the hardware device; and if no response is received, the GOS is kept paused.

Abstract: A method for using a mobile device to access remote host desktop applications. A client mobile device is connected to a remote server (host) over a WAN. The client mobile device launches host desktop applications remotely and loads the application windows onto its screen. The applications are executed on a remote host and the host application icons are loaded and rendered on a mobile device screen. The images are formed on the remote host as a result of execution of the applications. The host is connected to cloud cache storage. The host loads application icons onto the cloud cache storage. The icon hashes are generated. When a mobile client needs to launch the host application, the corresponding icon hashes are used for locating the required application icons in the cloud cache storage and loading them to the client mobile device.

A hypervisor-level monitoring of tested software products and GOSs is implemented.

Abstract: A method and computer program product for running a remote desktop application on a mobile device without audio interference from the other desktop applications, so the remote user applications runs as if it were a native mobile device application. A remote host desktop has a number of applications running simultaneously and producing sounds. A mobile device user selects one application and launches it on his mobile device. The selected application runs on a mobile device and the sounds produced by all other desktop applications are filtered out by special audio control driver implemented on the host system.

Abstract: A method for publishing the web sites on remote server using shared hosting in cases of unexpected server timeouts. A list of elements (work items) to be published is generated. The list is sorted out according to dependencies of elements from one another. Then, the work items are sorted out by the priority. The work item from the top of the list (with the highest priority) is processed first. After the work is performed with this work item, the work item is marked as closed if the process has executed successfully. Then, the process moves to the next work item and so on. The process has a library of the work items. Thus, in case of a server timeout, the process knows exactly which work items have been processed prior to the timeout and can start the processing from the next work item.

Abstract: A system, method and computer program product for implementing a video camera that is accessible by different Virtual Machine GOSs and the Host system. A standard USB video camera is build into a Host system. A VM running a Guest OS is launched on the Host system. The Guest OS has virtual driver for the Host video camera. The virtual driver is connected to a virtual USB bus, which communicates with a special Host library over a Virtual Machine Monitor (VMM). A special Host side VM application acquires and processes video data from a standard Host system video processing API that communicates directly with a Host-side virtual camera driver. Video frames are provided via the Host-side VM application to the virtual USB bus and to the virtual driver. Host applications or other VMs can acquire video streams from the Host USB camera simultaneously.

The key of the digital signature is used as a part of the installation package. The user downloads custom server software and installs it on his desktop over a secure connection. A vendor (or content provider) checks the validity of the user data and registers the application to the user. The application provider has a right to digitally sign the package.

Abstract: A first component of a Hypervisor is loaded into the memory upon start up. The first component is responsible for context switching and some interrupt handling. The first component of the Hypervisor runs on a root level. An OS is loaded into a highest non-root privilege level. A second component of the Hypervisor is loaded into OS space together with the OS, and running on the highest non-root privilege level. A Virtual Machine Monitor is running on the root level. The second component of the Hypervisor is responsible for (a) servicing the VMM, and (b) enabling communication between VMM code launched on non-root level with the first component of the Hypervisor to enable root mode for the VMM. A Virtual Machine is running on a user level under control of the VMM.

Abstract: A method and system for archiving file data used by a virtual container. The container uses “real files” and “balloon” files. The “real files” are the container file system files that are mapped to corresponding blocks of the host file system. The “real files” are mapped upon creation. The “balloon” files are also created in the container file system, but any links to the blocks of the host file system are invalidated (mapping is removed) and the blocks of the host file system corresponding to a balloon file are marked as free. A hypervisor, a host OS or a Virtual Machine Monitor frees up real physical blocks completely, so these blocks become available for writes in the host file system. Thus, all references indicating that these blocks are occupied are removed.

Abstract: A method and computer program product for targeted container virtualization, where only separate components of a computer system or a server are virtualized. The OS kernel and other server resources are not virtualized. Only selected components—applications or resources are targeted for virtualization instead of virtualization of the entire system. Targeted virtualization provides for more flexible container isolation from each other and from a host node. This, in turn, provides for optimized more flexible cloud infrastructure. Each element within a container virtualization model is optional in terms of virtualization. The element's virtualization option can be turned on and off by an administrator or by a client who owns the container.

Abstract: A system and method for implementing direct attachment of VMs, implemented on a computer system, to hardware devices attached to the computer system. Direct attachment architecture is implemented. The direct attachment is an exclusive dedication of a hardware device to a VM, where a particular hardware device is assigned to a particular VM. When the VM is not activated, the hardware device can be re-assigned to another VM. At system start up, hardware devices are masked from a host OS of a computer system and are automatically attached to the assigned VMs.

Abstract: A method for displaying non-native application windows on a computing system that has the host OS and a host desktop, the method including displaying the host desktop; upon a user invoking the non-native application by selecting an object associated with the non-native user application in the host OS, launching the non-native application on a server, wherein the non-native application is incompatible with the host OS and cannot execute under the host OS; and displaying the non-native application in a non-native application window on the computing system on the host OS desktop. The non-native application window has a native look-and-feel of the host OS, and control elements of the non-native application window appear native. Objects within the non-native application window can be drag-and-dropped to the host OS desktop as if they were native objects of the host OS.

Abstract: A host runs an operating system kernel. A plurality of virtual private servers (containers) is supported within the kernel. The containers use the same files. A template cache has pre-calculated file checksums. The checksum is calculated each time the file is created and/or modified. Each file has an inode containing an attribute indicating whether the checksum is calculated and stored along with the file. If the checksum is present, the process is redirected to access the file with the same inode in the shared disk cache.

Abstract: A system, method and computer program product for managing files of Virtual Machines, including launching a plurality of Virtual Machines in a computing system having a host OS. Content of at least one file of the host OS is used as a shared file. Using a re-direct, access is provided to the shared file when any Virtual Machine attempts to access its private file; using copy-on-write, a copy is made of the shared file if the Virtual Machine attempts to modify the shared file, and placed in a private area of the corresponding Virtual Machine. One of the Virtual Machines is used as master template, and includes shareable files to which attempts to access the file by other Virtual Machines are redirected. Access to the shared file from the Virtual Machine is implemented using stub files.
