摘要： Disclosed is a method, apparatus and a computer program of a virtual execution environment. In one aspect thereof a data processor includes a read-only storage medium and a virtual machine monitor configured to execute a program in a virtual container. Prior to execution of the application a set of application components accessed during a phase change are recorded in the read-only storage medium in a manner predetermined to minimize the time needed to retrieve the set of components. At the occurrence of the phase change, or prior to the occurrence of a phase change if the files are prefetched, the virtual machine monitor retrieves the components from the read-only storage medium. In a further aspect thereof there is provided a packager of an application to be executed in a virtualization environment by a virtual machine monitor. The packager is responsive to receiving notification from a virtual machine monitor of an occurrence of contemporaneous file accesses, not associated with a known phase change of a virtual container, to evaluate the occurrence as a candidate phase change, and responsive to the evaluation indicating a presence of a previously unknown phase change, for recording the files accessed on a new read-only storage medium in the order accessed for use by the same or a different virtual machine monitor during another instance of execution of the application.

摘要： Disclosed is a method, apparatus and a computer program of a virtual execution environment. In one aspect thereof a data processor includes a disk-based storage system and a virtual machine monitor configured to execute a program in a virtual container. The virtual machine monitor is responsive, prior to execution of the application, to record a set of files accessed during a phase change in the disk-based storage system in a manner predetermined to minimize the time needed to retrieve the set of files. The virtual machine monitor is further responsive, at the occurrence of the phase change, or prior to the occurrence of a phase change if the files are prefetched, to retrieve the files from the disk-based storage system. In a further aspect thereof there is provided a server of the virtual execution environment that includes a unit, responsive to receiving notification from the at least one virtual machine monitor of an occurrence of contemporaneous file accesses not associated with a known phase change of a virtual container, for evaluating the occurrence as a candidate phase change and, responsive to the evaluation indicating a presence of a previously unknown phase change, for adding a list of the files accessed to a phase change template for use by the same or a different virtual machine monitor during another instance of execution of the application.

摘要： Disclosed is a method, computer program product and a server unit of a virtual execution environment having at least one client. The server unit includes a network interface for conducting bidirectional communications with the at least one client and a control unit configured to determine, for individual ones of positions in a virtualized execution of an application, those components that are required at each position; to establish a pseudo-distance between the positions in the virtualized execution of the application; and to identify components that are candidates for prefetching as those components required at one or more positions that are proximate to a current position. The pseudo-distance between positions is indicative of an urgency of prefetching candidate components for regulating an amount of resources devoted to the prefetching of components.

摘要： A novel method is disclosed for capturing an installed state of a conventional application and converting the captured state into a virtual application. The novel method starts with a bare machine in a known state, preferably soon after the OS was installed. Installation scripts are used to install one or more software applications along with required components and dependencies. Other artifacts can be added and configured such as files, trees, directories, entries, data, values, among others. These also may include updates to various system databases, such as the Windows registry in which certain metadata is stored. The installed applications are tested and verified to work as desired. Undesired artifacts can be deleted manually or removed by the OS. The state of the virtual machine with the installed applications is captured. The installed applications can be tested on the frozen virtual machine. If the user determines that the installed applications are working properly, a virtual machine image is prepared and then written out. The resulting output is a new populated virtual application container that encapsulates the applications installed and configured by the user. If the user determines that one or more installed applications do not work properly during testing, then the frozen virtual machine can be unfrozen and any deficiencies corrected. The virtual machine image is stored as a launch document and a set of shards. The virtual machine image represents the state of the virtual machine along with the installed applications at the time the preparation virtual machine was frozen.
