VirtualBox - это семейство продуктов для любой архитектуры, представляющие собой средство для виртуализации как для корпоративных, так и домашних пользователей. В отличие от альтернативных разработок, данное решение распространяется как программное обеспечение с открытым исходным кодом. Программа работает в среде практически всех современных операционных систем, начиная с Windows и заканчивая Solaris с MacOS X, поддерживая при этом большое число гостевых ОС, среди которых: Windows (NT 4.0, 2000, XP, Server 2003, Vista), DOS/Windows 3.x, Linux (с ядрами версий 2.4 и 2.6), OpenBSD, и прочие. 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.
Cистема виртуализации, аналогичная VMware Workstation и Microsoft Virtual PC
Sun xVM VirtualBox - система виртуализации, аналогичная VMware Workstation. Несколько ограниченная в своих возможностях версия продукта выпускается с открытым исходным кодом под лицензией GPL. Поддерживает образы VMware. Плюсы:компакность, модульность, расширяемость, высокая производительность. Для тех, кто не слышал про WMVare и Microsoft VirtualPC: эти программы предназначены для создания виртуальной машины с параметрами железа реального (вашего) компьютера, на которой можно запускать любую операционную систему. Крайне удобная функция, например, для тестеров... VirtualBox is a powerful x86 and AMD64/Intel64 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) version 2.

Извините за флуд, но по поиску не нашёл темы для вопросов и решения проблем, то пишу сюда. Кто-то пробывал ставить VirtualBox-3.1.2-56127-Win? У меня постоянно выскакивает ошибки "Не удалось подключить образ оптического диска...." Код ошибки: E_FAIL (0x80004005) Уже на другом компе пробывал где тоже Windows Se7en и здесь переустанавливал. И тоже само. Кто знает, что за прикол?

Linux and macOS use native engine while for Windows host it is separately implemented. GUI: Large icon update. Audio recording: Now using Vorbis as the default audio format for WebM containers. Opus is no longer being used. Audio: Added "default" host driver type to make it possible to move VMs (appliances) between different platforms without the need of changing the audio driver explicitly. When the "default" driver is selected, the best audio backend option for a platform will be used. This is the default for newly created VMs. Guest Control: Implemented initial support for automatic updating of Guest Additions for Linux guests Guest Control: Implemented ability to wait for and/or reboot the guest when updating Guest Additions via VBoxManage VBoxManage: Added Guest Control "waitrunlevel" sub-command to make it possible to wait for a guest to reach a certain run level Windows hosts: Added experimental support of running autostarted VMs in session 0, to allow running VMS even when a usser is not being logged in (disabled by default, please consult the manual) macOS host: Dropped all kernel extensions. VirtualBox relies fully on the hypervisor and vmnet frameworks provided by Apple now. At the moment the implementation lacks "Internal Networking" functionality. This will be provided at a later date. macOS host: Providing a Developer Preview package for systems with an Apple silicon CPU. This is unsupported work in progress, and is known to have very modest performance. Linux Guest Additions: Reworked guest screen re-size functionality, added basic integration with some of guest Desktop Environments Devices: Implemented new 3D support based on DirectX 11 (and DXVK on non Windows hosts) Devices: Added virtual IOMMU devices (Intel and AMD variant) Devices: Added virtual TPM 1.2 and 2.0 devices Devices: The EHCI and XHCI USB controller devices are now part of the open source base package EFI: Added support for Secure Boot Debugging: Added experimental support for guest debugging through GDB and highly experimental support for guest debugging through KD/WinDbg
VMM: Fixed guru running the FreeBSD loader on older Intel CPUs without unrestricted guest support (bug #21332) GUI: Fixed virtual machines grouping when VM was created or modified in command line (bugs #11500, #20933) GUI: Introduced generic changes in settings dialogs VirtioNet: Fixed broken network after loading saved state (bug #21172) Storage: Added support for increasing the size of the following VMDK image variants: monolithicFlat, monolithicSparse, twoGbMaxExtentSparse, twoGbMaxExtentFlat VBoxManage: Added missing --directory switch for guestcontrol mktemp command Mouse Integration: Guest was provided with extended host mouse state (bug #21139) DnD: Introduced generic improvements Guest Control: Fixed handling creation mode for temporary directories (bug #21394) Linux Host and Guest: Added initial support for building UEK7 kernel on Oracle Linux 8 Linux Host and Guest: Added initial support for RHEL 9.1 kernel Windows Host: Fixed support for VM autostart (bug#21349) Linux Guest Additions: Added initial support for kernel 6.2 for vboxvideo Audio: The "--audio" option in VBoxManage is now marked as deprecated; please use "--audio-driver" and "--audio-enabled" instead. This will allow more flexibility when changing the driver and/or controlling the audio functionality

Предоставлена возможность отключения верификации модулей ядра Linux по цифровой подписи через указание параметра VBOX_BYPASS_MODULES_SIGNATURE_CHECK="1" в файле /etc/vbox/vbox.cfg для хост-окружений и в файле /etc/virtualbox-guest-additions.conf для гостевых систем. Добавлена начальная поддержка ядра Linux 6.3. В дополнениях для гостевых систем на базе Linux добавлена экспериментальная поддержка перезагрузки модулей ядра и пользовательских сервисов после окончания установки VirtualBox, что позволяет обойтись без перезагрузки всей системы после обновления набора Guest Additions. В VBoxManage добавлена команда "modifynvram enrollmok" для добавления ключа MOK (Machine Owner Key) в NVRAM, который может использоваться для верификации модулей ядра гостевой системы с Linux. Добавлен API для добавления цифровых подписей в список MOK (Machine Owner Key). В дополнениях для гостевых систем на базе Linux улучшено определения использования systemd для инициализации системы. Решены проблемы со сборкой модуля vboxvideo при использовании ядер из состава RHEL 8.7, 9.1 и 9.2. В менеджере виртуальных машин улучшена поддержка вложенного запуска виртуальных машин. Устранены проблемы, проявлявшиеся при использовании гипервизора Hyper-V. Налажен запуск гостевых систем с UEFI при использовании macOS 13.3+. В GUI в диалоге закрытия виртуальной машины возвращён флаг для восстановления текущего снапшота, решены проблемы с записью значения порта в редакторе USB-фильтров, налажено редактирование имени VM и типа ОС в панели с детальной информацией о виртуальной машине. В Oracle VM VirtualBox Extension Pack решены проблемы с поставкой криптографического модуля для обеспечения полного шифрования виртуальной машины. Для драйвера E1000 упрощён процесс смены привязки к сети. В virtio-net добавлены изменения для улучшения поддержки FreeBSD 12.3 и pfSense 2.6.0. Решены проблемы с графикой, проявлявшиеся при использовании гостевых систем с Windows 7

VirtualBox - это семейство продуктов для любой архитектуры, представляющие собой средство для виртуализации как для корпоративных, так и домашних пользователей. В отличие от альтернативных разработок, данное решение распространяется как программное обеспечение с открытым исходным кодом. Программа работает в среде практически всех современных операционных систем, начиная с Windows и заканчивая Solaris с MacOS X, поддерживая при этом большое число гостевых ОС, среди которых: Windows (NT 4.0, 2000, XP, Server 2003, Vista), DOS/Windows 3.x, Linux (с ядрами версий 2.4 и 2.6), OpenBSD, и прочие. 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.
