Oracle VirtualBox is a virtual machine software produced by the German InnoTek software company. It is now developed by Oracle and is part of Oracle's xVM virtualization platform technology. It allows users to virtualize other x86 operating systems on 32-bit or 64-bit Windows, Solaris and Linux operating systems. Users can install and run Solaris, Windows, DOS, Linux, OS/2 Warp, OpenBSD, FreeBSD and other systems as client operating systems on VirtualBox.
Compared with VMware and Virtual PC of the same nature, VirtualBox's unique features include support for Remote Desktop Protocol (RDP), iSCSI and USB. VirtualBox can already support USB 2.0 hardware devices on the guest operating system.
VirtualBox was initially offered as a proprietary software protocol. In January 2007, InnoTek released VirtualBox as free software under the GNU General Public License (GPL), and provided binary and open source versions of the code.
simulated environment
Multiple client operating systems can be installed, and each client system can be opened, paused and stopped independently. Both the host operating system and the client operating system can communicate with each other. In an environment where multiple operating systems are running at the same time, each other can also use the network at the same time.
Hardware emulation
VirtualBox supports Intel VT-x and AMD AMD-V hardware virtualization technology.
The hard disk is simulated in a special container called a virtual disk image file (Virtual Disk Images). Currently, this format is not compatible with other virtual machine platforms. It is usually stored as a system file in the host operating system (extension .vdi). VirtualBox can connect to iSCSI and operate on virtual hard disks. In addition, VirtualBox can read and write VMware VMDK files and VirtualPC VHD files.
ISO image files can be mounted as CD/DVD devices. For example, downloaded Linux distribution DVD image files can be used directly in VirtualBox without burning them on a disc, or a physical optical drive can be mounted directly on a virtual machine.
By default, VirtualBox provides a VESA-compatible virtual graphics card, and an additional driver for Windows, Linux, Solaris, and OS/2 client systems, which can provide better performance and functionality, such as when the virtual machine's window is zoomed , the resolution will be dynamically adjusted.
In terms of sound cards, VirtualBox virtualizes an Intel ICH AC97 sound card and SoundBlaster 16 sound card.
In terms of Ethernet adapters, VirtualBox virtualizes several network cards: AMD PCnet PCI II, AMD PCnet-Fast III, Intel Pro/1000 MT Desktop, Intel Pro/1000 MT Server, and Intel Pro/1000 T Server.
Change log
—Supports two-way drag and drop files on all Windows platforms;
—Support USB 3.0 devices: the virtual machine system can recognize the USB3.0 interface;
—Improved CPU utilization: the software can take advantage of the latest hardware instructions to achieve maximum performance;
—Improved disk image encryption: using the industry-standard AES algorithm, which helps ensure data security;
—Added editing menu, VM window shortcut icon and other functions.
