VirtualBox практически не уступает подобным коммерческим разработкам (если не считать порой замедленной скорости работы). Имеются средства для работы с периферийными устройствами на основных ПК, возможно включение в сеть, удаленное управление, присутствуют средства для обмена файлами, а также специальные пакеты с ПО и драйверами для гостевых ОС, которые предназначены для повышения производительности. Для полноценной работы с VirtualBox необходимо при первом запуске зарегистрироваться, введя свое имя и адрес электронной почты.

Ключевые особенности:
» Кроссплатформенность
» Модульность
» Поддержка USB 2.0, когда устройства хост-машины становятся доступными для гостевых ОС (только в проприетарной версии)
» Встроенный RDP-сервер, а также поддержка клиентских USB-устройств поверх протокола RDP (только в проприетарной версии)
» Экспериментальная поддержка образов жестких дисков VMDK/VMware
» Поддержка iSCSI (только в проприетарной версии)
» Поддержка виртуализации аудиоустройств
» Поддержка различных видов сетевого взаимодействия (NAT, Host Networking via Bridged, Internal)
» Поддержка дерева сохраненных состояний виртуальной машины (snapshots), к которым может быть произведен откат из любого состояния гостевой системы
» Поддержка Shared Folders для простого обмена файлами между хостовой и гостевой системами
