Abstract: Methods and systems for generating code for a device are disclosed. A device command for which the code is to be generated is selected. Response template parameters for the selected device commands are retrieved from a response template associated with the device command. Command syntax for the selected device commands are retrieved from a device library associated with the device command. The code is generated for the device in a high level language and the response template parameters are incorporated to provide verification of the device response when the test code is executed.

Abstract: A process of providing access to data associated with a virtual machine running on a host computer system to an offload server is implemented to improve the performance of the host computer system. Once the offload computer system knows how and where to access the data associated with that of the virtual machine, operations can be offloaded from the host computer system and performed by the offload server. Backup operations can be offloaded onto the server. The server can run backup software and directly access the data associated with the virtual machine, thereby freeing the hardware resources of the host computer to handle normal applications running on the virtual machine.

Abstract: A service level management (SLM) system where the system learns the structure of a web application, monitors the operation of the application, and controls the processing of incoming requests to achieve optimal performance as defined in a service level agreement (SLA). The system is operative for example in enterprise web applications and in enterprise data centers that deploy web applications and optimally is capable of controlling and maintaining a level of service of web applications.

Abstract: The invention virtualizes a computer that includes a host computer system, which comprises a processor, memory, and physical system devices. A conventional operating system (referred to below as the “host operating system” or “HOS”) is installed on the hardware. A computer program product that is executable within the host computer system comprises computer-executable code for implementing an interface software layer, preferably a virtual machine monitor, between the host system and a virtual machine; for reading in and storing state information of the processor associated with the HOS; and for logically decoupling the HOS from the processor with respect to pre-determined functions of the interface software layer and the virtual machine by setting the processor state information to settings associated with the interface software layer.

Abstract: A method for customizing the response for network based intrusion prevention comprising of: 1) virtual proxying the application data to enable custom response 2) enhancing transport layer (TCP/IP) to enable selective processing and selective modification of the stream for intrusion prevention. The invention also discloses a method for customizing the processing for both network or host based intrusion prevention comprising of: 1) loading externally defined processing procedures for the detection and prevention of intrusions 2) combining multiple of these processing procedures to form a unified processing engine that can be used for intrusion detection and prevention 3) unloading processing procedures that are not needed any more 4) loading new processing procedures that improve the intrusion detection and prevention.

Abstract: An architecture and system are described that provide a unified file access service within in a managed computing environment composed of diverse networks, computing devices, and storage devices. The service provides mechanisms for remotely accessing the file systems of any managed computer or disk snapshot, independently of the computer's current state (powered on, suspended or powered off), its location within the environment, its hardware type (virtual vs. physical), its operating system type, and its file system formats. The system isolates centralized FPAs from the details of clients, proxies and storage elements by providing a service that decomposes offloaded file system access into two steps. A FPA or a requester acting on behalf of the FPA first expresses the disk set or the computer containing the file systems it wishes to access, along with requirements and preferences about the access method.

Abstract: A provisioning server automatically configures a virtual machine (VM) according to user specifications and then deploys the VM on a physical host. The user may either choose from a list of pre-configured, ready-to-deploy VMs, or he may select which hardware, operating system and application(s) he would like the VM to have. The provisioning server then configures the VM accordingly, if the desired configuration is available, or it applies heuristics to configure a VM that best matches the user's request if it isn't. The invention also includes mechanisms for monitoring the status of VMs and hosts, for migrating VMs between hosts, and for creating a network of VMs.

Abstract: Methods and systems for sharing memory pages in virtual machines are described. Guest memory pages are identified as candidate memory pages. The candidate memory pages are hashed and the hash results of the candidate memory pages are compared. A determination is made on whether a hash match exists between a first candidate memory page and a second candidate memory page. If it is determined that a hash match exists, an anonymous memory page that includes the information of candidate memory pages is created and shared. As a result, embodiments effectively reduce memory overheads by, in one example, exposing a single anonymous memory page to multiple virtual machines.
