A code inspection tool comprises a plurality of physical computing resources connected by a network facility, eg an LAN, intranet or internet, and a voice conferencing communications facility. The code inspection tool interfaces with a known configuration management system to load a quantity of original source code. A group of developers use a plurality of graphical user interfaces to inspect the code. All graphical user interfaces log into display views generated on a main graphical user interface, which is operated by a human controller of a code inspection session. The code inspection tool comprises means for allowing developers to compile annotation data and forward the annotation data from their respective graphical user interfaces to a centralized data store. Internal algorithms of the code inspection tool compile markers relating the annotation data files to individual lines of source code. During a code inspection session, all developers view a same display, which sets out original source code, side by side with new source code on a line by line basis, matching the line numbers of the original source code with those of the new source code. Changes to the original source code and new source code are visually identified by automatic generation of icons next to the appropriate source code lines on the display. Annotations to the source code lines are indicated by further icons next to the appropriate lines. The tool automatically generates data describing statistics of a code inspection process, for example number of lines inspected, during of a code inspection session, proportion of original and new code lines inspected. Code inspection reports may be generated in a variety of formats, eg plain text or HTML, and automatically distributed to individual developers over the networked facility.

In a virtualized system running one or more virtual machines on a first hypervisor, a second hypervisor is installed and control of the hardware resources of the physical computer supporting the virtualized system is migrated from the first hypervisor to the second hypervisor without interrupting the operation of the first hypervisor and the virtual machines. Initially a minimal set of hardware resources is hot-removed from control by the first hypervisor, and the second hypervisor is launched on the minimal set of hardware resources. Both the remaining hardware resources and the virtual machines are then migrated from the first hypervisor to the second hypervisor until all the virtual machines have been migrated over to the second hypervisor, while the virtual machines and the first hypervisor continue running largely unaffected by the migration process.

Embodiments of the present invention are directed to the running of a virtual machine directly from a physical machine using snapshots of the physical machine. In one example, a computer system performs a method for running a virtual machine directly from a physical machine using snapshots of the physical machine. A snapshot component takes a snapshot of the physical system volume while the physical system volume is in an operational state. The virtual machine initializes using the physical system volume snapshot thereby allowing the physical system volume snapshot to be a virtual system volume snapshot representing an initial state of a virtual system volume. The physical system volume snapshot includes instances of all the files within the physical system volume at the time the snapshot was taken.

A method for enforcing a network policy is described herein. In the method, a network socket event request from an application executing in a first context is intercepted by an agent prior to the request reaching a transport layer in the first context. A context refers to virtualization software, a physical computer, or a combination of virtualization software and physical computer. In response to the interception of the request, the agent requests a decision on whether to allow or deny the network socket event request to be communicated to a security server executing in a second context that is distinct from the first context. The request for a decision includes an identification of the application. The agent then receives from the security server either an allowance or a denial of the network socket event request, the allowance or denial being based at least in part on the identification of the application and a security policy. The agent blocks the network socket event from reaching the transport layer when the denial is received from the security server. In one embodiment, the method is implemented using a machine readable medium embodying software instructions executable by a computer.

Methods, devices, and systems are described for diverting a computer hacker from a physical or other targeted production computer to a decoy software-based host emulator that emulates the physical computer. The decoy has the exact same IP address as the physical computer. In order to avoid packet collisions, a programmable physical switch and a virtual networking switch are employed, both of which can use software-defined networking (SDN). The virtual switch prevents packets from the decoy from flowing out of its virtual network until commanded. Upon a command, the physical switch redirects specific flows to the virtual switch, and the virtual switch opens specific flows from the decoy. The specific flows are those with packets containing the hacker's computer IP address, production computer IP address, and production computer port. The packets are associated with TCP connections or UDP sessions. The decoy host emulator can be a virtual machine (VM) running alongside many other VMs in a single computer. If the hacker performs a horizontal scan of the network, additional flows are diverted to other decoy host emulators.

Various embodiments of the present invention are directed to systems and methods for “attaching” a virtual hard drive to the physical computer hardware by implementing a specialized disk controller driver for the host operating system that is recognized by the host operating system as a disk controller driver but which in fact also emulates the virtual hard disk it is “attached” to. When the host operating system sends requests to read and write sectors from the virtual hard drive, the specialized driver (the “virtual hard drive controller driver”) directly accesses and manipulates the back-end file mentioned above. Thus the virtual disk is “attached” and recognizable by the host operating system and can be manipulated thereby (and applications executing thereon).
