In computer science, virtualization is a modern technique developed in late 1990s and is different from simulation and emulation. Virtualization employs techniques used to create instances of an environment, as opposed to simulation, which models the environment; or emulation, which replicates the target environment such as certain kind of virtual machine environment. Full virtualization requires that every salient feature of the hardware be reflected into one of several virtual machines – including the full instruction set, input/output operations, interrupts, memory access, and whatever other elements are used by the software that runs on the bare machine, and that is intended to run in a virtual machine. In such an environment, any software capable of execution on the raw hardware can be run in the virtual machine and, in particular, any operating systems. The obvious test of full virtualization is whether an operating system intended for stand-alone use can successfully run inside a virtual machine.
End-to-end virtualization
InactiveUS20120099602A1Facilitates end-to-end virtualizationData switching by path configurationData virtualizationNetwork virtualization
One embodiment of the present invention provides a system that facilitates end-to-end virtualization. During operation, a network interface residing on an end host sets up a tunnel. The network interface then encapsulates a packet destined to a virtual machine based on a tunneling protocol. By establishing a tunnel that allows a source host to address a remote virtual machine, embodiments of the present invention facilitate end-to-end virtualization.

Malware protection using file input/output virtualization
Applications running in an API-proxy-based emulator are prevented from infecting a PC's hard disk when executing file I / O commands. Such commands are redirected to an I / O redirection engine instead of going directly to the PC's normal operating system where it can potentially harm files in on the hard disk. The redirection engine executes the file I / O command using a private storage area in the hard disk that is not accessible by the PC's normal operating system. If a file that is the subject of a file I / O command from an emulated application is not in the private storage area, a copy is made from the original that is presumed to exist in the public storage area. This copy is then acted on by the command and is stored in the private storage area, which can be described as a controlled, quarantined storage space on the hard disk. In this manner the PC's (or any computing device's) hard disk is defended from potential malware that may originate from applications running in emulated environments.

Integrated storage virtualization and switch system
ActiveUS7747836B2Improve writing efficiencyElimination of storage “hot spots”TransmissionMemory systemsOperational systemData access
A system integrates an intelligent storage switch with a flexible virtualization system to enable efficient service of file and block protocol data access requests for information stored on the system. A storage operating system executing on a storage system coupled to the switch implements the virtualization system to provide a unified view of storage to clients by logically organizing the information as named files, directories and logical unit numbers. The virtualization system is illustratively embodied as a file system having a write allocator configured to provide a flexible block numbering policy that addresses volume management capabilities, such as storage virtualization, at a finer granularity (e.g., a single block) than that of previous non-flexible storage virtualization schemes. The flexible block numbering policy also yields substantial benefits in terms of increased write efficiency and elimination of storage “hot spots”, as well as a compelling point-in-time read-only data image (snapshot) mechanism.

Methods and apparatus involve monitoring spin locks for guest devices. Fully virtualized guests have multiple virtual processors configured under the scheduling control of a hypervisor on a physical hardware platform. The hypervisor posts On CPU and CR3 load information to shared communications pages for each of the processors. A monitoring module in the guest device monitors the pages to ascertain forward progress of the processors. If forward progress is being made, the virtual processors continue to spin. If not, the CPU's control is variously relinquished. The monitoring module typifies a kernel driver so that the guest can maintain an unmodified operating system. Ticket spin locks, and their ordering, are also considered as are computations for lock owners. Other features contemplate computing systems and computer program products, to name a few.
