VirtualBox - cистема виртуализации, для запуска и работы на одном компьютере нескольких виртуальных операционных систем, аналогичная VMware Workstation и MS Virtual PC. Поддерживает динамическую трансляцию - выполнение большей части инструкций гостевой ОС производится на реальном оборудовании. В качестве хост-систем поддерживаются 32- и 64-битные версии Linux, Windows, Mac OS, Solaris, а в роли гостевой системы могут выступать Windows, GNU/Linux, BSD, Solaris и другие операционные системы. Плюсы: компактность, поддержка образов VMware, высокая производительность. Предназначена для создания виртуальной машины с параметрами реального железа (вашего) компьютера, на которой можно запускать любую операционную систему.
Ключевые особенности программы :* VirtualBox может управляться как через GUI-интерфейс, так и через командную строку.
* Для расширения функций программы разработан специальный комплект SDK.
* Параметры виртуальных машин описываются в формате XML и никак не зависят от того физического компьютера, на котором система работает. Поэтому виртуальные компьютеры формата VirtalBox легко переносить с одного ПК на другой.
* При испозовании на "гостевых" компьютерах операционных систем Windows можно воспользоваться специальными утилитами, значительно облегчающими переключение между физическим и виртуальными компьютерами.
* Для быстрого обмена файлами между гостевым и физическим ПК можно создавать так называемые "разделяемые каталоги" (Shared folders), которые одновременно доступны из обоих этих машин.
* VirtualBox позволяет подключать USB-устройства к виртуальным компьютерам, позволяя виртуальным машинам работать с ними напрямую.
* VirtualBox полностью поддерживает протокол удалённого доступа RDP (Remote Desktop Protocol). Виртуальная машина может работать как RDP-сервер, позволяя управлять ею удалённо.
* Поддержка виртуализации аудиоустройств
Виртуализация дает чудесный и удобный инструмент для эффективного использования в качестве тестового окружения или переносного программного обеспечения разработчика. Чем сложнее программный проект, чем больше у него внешних зависимостей, тем больше выгод может дать его виртуализация.Большие плюсы программы: кроссплатформенность, бесплатность, удобное управление через ком.строку, отличная документация, высокая скорость работы,

Тестирование.Очень удобная программа, работает без установки и гораздо меньше VMware Workstation. Простой и доходчивый мастер помогает очень быстро, за пару минут, создать новый образ. У меня стоит ХР, создал образ Росинки (Linux) с CD. Все работает. Можно одновременно работать в дыух системах, если не забывать через правую Ctrl (стоит по умолчанию в VirtualBox) переключать клавиатуру между системами. Затем создал еще две системы - Windows 7 и ХР, но источники уже iso на жестком диске. Все функционирует.
Не обошлось и без:
FATAL: No bootable medium found! System halted (FATAL: Загрузочный носитель не найден! Система остановлена) - такое получил на двух последних, скачанных в июле, iso Windows 7 Extended Edition (2010/RUS/RePack by ...). И к чему это? А к тому, что сейчас каждый день море новых версий сборок Windows 7 от "умельцев". Распрастраняются быстрее вирусов. Но какая часть из них рабочая? Легкий заработок в интернете!!! - это сейчас так называется.
VirtualBox is a powerful x86 virtualization product for enterprise as well as home use. Not only is VirtualBox an extremely feature rich, high performance product for enterprise customers, it is also the only professional solution that is freely available as Open Source Software under the terms of the GNU General Public License (GPL). See "About VirtualBox" for an introduction.
Presently, VirtualBox runs on Windows, Linux, Macintosh and OpenSolaris hosts and supports a large number of guest operating systems including but not limited to Windows (NT 4.0, 2000, XP, Server 2003, Vista, Windows 7), DOS/Windows 3.x, Linux (2.4 and 2.6), Solaris and OpenSolaris, and OpenBSD.
VirtualBox is being actively developed with frequent releases and has an ever growing list of features, supported guest operating systems and platforms it runs on. VirtualBox is a community effort backed by a dedicated company: everyone is encouraged to contribute while Sun ensures the product always meets professional quality criteria.
VirtualBox is a general-purpose full virtualizer for x86 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software.
Some of the features of VirtualBox are:
* Modularity. VirtualBox has an extremely modular design with well-defined internal programming interfaces and a client/server design. This makes it easy to control it from several interfaces at once: for example, you can start a virtual machine in a typical virtual machine GUI and then control that machine from the command line, or possibly remotely. VirtualBox also comes with a full Software Development Kit: even though it is Open Source Software, you don't have to hack the source to write a new interface for VirtualBox.
* Virtual machine descriptions in XML. The configuration settings of virtual machines are stored entirely in XML and are independent of the local machines. Virtual machine definitions can therefore easily be ported to other computers.
* Guest Additions for Windows and Linux. VirtualBox has special software that can be installed inside Windows and Linux virtual machines to improve performance and make integration much more seamless. Among the features provided by these Guest Additions are mouse pointer integration and arbitrary screen solutions (e.g. by resizing the guest window).
* Shared folders. Like many other virtualization solutions, for easy data exchange between hosts and guests, VirtualBox allows for declaring certain host directories as "shared folders", which can then be accessed from within virtual machines.
A number of extra features:
* Virtual USB Controllers. VirtualBox implements a virtual USB controller and allows you to connect arbitrary USB devices to your virtual machines without having to install device specific drivers on the host.
* Remote Desktop Protocol. Unlike any other virtualization software, VirtualBox fully supports the standard Remote Desktop Protocol (RDP). A virtual machine can act as an RDP server, allowing you to "run" the virtual machine remotely on some thin client that merely displays the RDP data.
* USB over RDP. With this unique feature, a virtual machine that acts as an RDP server can still access arbitrary USB devices that are connected on the RDP client. This way, a powerful server machine can virtualize a lot of thin clients that merely need to display RDP data and have USB devices plugged in.
* Visual Studio .NET 2003 or Visual Studio 2005 with service pack 1.
* Windows Platform SDK coming with Visual C++ or a more recent one from:
