In computing, a virtual machine VM is an emulation of a computer system. Virtual machines are based on computer architectures and provide functionality of a physical computer.
Their implementations may involve specialized hardware, software, виртуальная машина online, or a combination. Some virtual machines, such as QEMUare designed to also emulate different architectures and allow execution of software applications and operating systems written for another CPU or architecture.
A VM or virtual machine was originally defined by Popek and Goldberg as "an efficient, isolated duplicate of a real computer machine.
The desire to run multiple operating systems was the initial motive for virtual machines, so as to allow time-sharing among several single-tasking operating systems. In some respects, a system virtual machine can be considered a generalization of the concept of virtual memory that historically preceded it. Unlike virtual memory, a system virtual machine entitled the user to write privileged instructions in their code.
As technology evolves virtual memory for purposes of virtualization, new systems of memory overcommitment may be applied to manage memory sharing among multiple virtual machines on one computer operating system. It may be possible to share memory pages that have identical contents among multiple virtual machines that run on the same physical machine, what may result in mapping them to the same physical page by a technique termed Kernel SamePage Merging.
This is especially useful for read-only pages, such as those holding code segments, which is the case for multiple virtual machines running the same or similar software, software libraries, web servers, middleware components, etc.
The guest operating systems do not need to be compliant with the host hardware, thus making it possible to run different operating systems on the same computer e.
The use of virtual machines to support separate guest operating systems is popular in regard to embedded systems. A typical use would be to run a real-time operating system simultaneously with a preferred complex operating system, such as Linux or Windows. Another use would be for novel and unproven software still in the developmental stage, so it runs inside a sandbox.
Virtual machines have other advantages for operating system development, and may include improved debugging access and faster reboots.
Multiple VMs running their own guest operating system are frequently engaged for server consolidation. Both system virtual machines and process virtual machines date to the s, and continue to be areas of active development.
System virtual machines grew out of time-sharingas notably implemented in the Compatible Time-Sharing System CTSS. Time-sharing allowed multiple users to use a computer concurrently: Emulatorswith hardware emulation of earlier systems for compatibility, date back to the IBM in[6] [7] while the software emulation then-called "simulation" predates it.
Process virtual machines arose originally as abstract platforms for an intermediate language used as the intermediate representation of a program by a compiler ; early examples date to around An early example was the O-code machinea virtual machine which executes O-code object code emitted by the front end of the BCPL compiler.
This abstraction allowed the compiler to be easily ported to a new architecture by implementing a new back end that took the existing O-code and compiled it to machine code for the underlying physical machine. The Euler language used a similar design, with the intermediate language named P portable. This has been influential, and virtual machines in this sense have been often generally called p-code machines. In addition to being an intermediate language, Pascal p-code was also executed directly by an interpreter implementing the virtual machine, notably in UCSD Pascal ; this influenced later interpreters, notably the Java virtual machine JVM.
Another early example was SNOBOL4which was written in the SNOBOL Implementation Language SILan assembly language for a virtual machine, which was then targeted to physical machines by transpiling to their native assembler via a macro assembler.
These techniques proved commercially successful in in the HotSpot Java virtual machine. In full virtualization, the virtual machine simulates enough hardware to allow an unmodified "guest" OS one designed for the same instruction set to be run in isolation.
This approach was pioneered in with the IBM CP and CPpredecessors of the VM family. Examples outside the mainframe field include Parallels WorkstationParallels Desktop for MacVirtualBoxVirtual IronOracle VMVirtual PCVirtual ServerHyper-VVMware WorkstationVMware Server discontinued, formerly called GSX ServerVMware ESXiQEMUAdeosMac-on-LinuxWin4BSD, Win4Lin Proand Egenera vBlade technology.
In hardware-assisted virtualization, the hardware provides architectural support that facilitates building a virtual machine monitor and allows guest OSes to be run in isolation. In andIntel and AMD provided additional hardware to support virtualization. Sun Microsystems now Oracle Corporation added similar features in their UltraSPARC T-Series processors in Examples of virtualization platforms adapted to such hardware include KVMVMware WorkstationVMware FusionHyper-VWindows Virtual PCXenParallels Desktop for MacOracle VM Server for SPARCVirtualBox and Parallels Workstation.
Infirst-generation and bit x86 hardware support was found to rarely offer performance advantages over software virtualization. In operating-system-level virtualization, a physical server is virtualized at the operating system level, enabling multiple isolated and secure virtualized servers to run on a single physical server.
The "guest" operating system environments share the same running instance of the operating system as the host system. Thus, the same operating system kernel is also used to implement the "guest" environments, and applications running in a given "guest" environment view it as a stand-alone system.
The pioneer implementation was FreeBSD jails ; other examples include DockerSolaris ContainersOpenVZLinux-VServerLXCAIX Workload PartitionsParallels Virtuozzo Containers, and iCore Virtual Accounts.
