Abstract: Systems and methods for deploying a virtual machine (VM) on a host are provided. An exemplary method comprises notifying a host to download a master copy of a VM image from a remotely located network storage device, in response to a service provider providing a definition manifest for a service request supported by the VM, wherein the host deploys the VM directly from the VM image downloaded to a storage medium locally connected to the host machine, wherein deployment of the VM allows the host to locally service the service request associated with the definition manifest, wherein the host replicates copies of the VM image, in response to receiving additional service requests to create one or more VM clones; wherein the host customizes the one or more VM clones based on the definition manifest.

Abstract: A revision control service is included in a hypervisor. The revision control service manages revision control operations relating virtual machine images transparently to the virtual machine. The revision control service interacts with a conventional revision control program, stores relevant revision control metadata external to the virtual machine image with file-level granularity, and synchronizes virtual machine operations with the revision control operations. From the perspective of the virtual machine, the revision control service provides a clean image from which to boot, without modification of the revision control program.

Abstract: A system and method for creating N customized disk images from N identical disk images. A computing system creates N identical disk images from a master image. The computing system customize a first identical disk image according to a customization written in customization scripts. While customizing the first identical disk image, the computing system monitors block-level operations applied on the first identical disk image. The computing system applies the monitored block-level operations simultaneously to other N?1 identical disk according to similar customizations written in customization scripts. After applying the block-level operations, the N identical disk images become N customized disk images. Identical Virtual Machines (VMs) operating in the N identical disk images become N customized VMs by operating based on the N customized disk images.

Abstract: Some demonstrative embodiments of the invention include, for example, devices, systems and methods of operating one or more virtual logical sites. A method may include, for example, running on a server at least one first virtual machine implementing at least part of a first virtual logical site, and at least one second virtual machine implementing at least part of a second virtual logical site interchangeable with the first virtual logical site. Other embodiments are described and claimed.

Abstract: Disclosed are methods and systems for performing a change-over to one or more components of a computing system. As part of a change-over procedure to one or more system components (i.e. software routines) of a production computing system, a clone of one or more production system components of the production computing system may be generated on the same computing platform as the production computing system component is running. According to some embodiments of the present invention, “virtualization” is one technique which may be used to generate and maintain a clone system component or virtual machine.

Abstract: A method for encoding a digitized speech signal so as to generate data capable of being decoded as speech. A digitized speech signal is first converted to a series of feature vectors using for example known Mel-frequency Cepstral coefficients (MFCC) techniques. At successive instances instance of time a respective pitch value of the digitized speech signal is computed, and successive acoustic vectors each containing the respective pitch value and feature vector are compressed so as to derive therefrom a bit stream. A suitable decoder reverses the operation so as to extract the features vectors and pitch values, thus allowing speech reproduction and playback. In addition, speech recognition is possible using the decompressed feature vectors, with no impairment of the recognition accuracy and no computational overhead.
