Unofficial tests affirm that VDI files are smaller and perform better than VHD or VHDX.

The latter means you can expand an image file after it has been created-even if it already contains data. It allows both fixed-size and dynamically allocated storage. VDI is portable and can be run using other virtualization programs. Virtual disks created using VirtualBox have a. Since it is open-source, a wide range of support tools that can be used with the software is also available from the VirtualBox ecosystem. If you are looking at using VirtualBox for your virtualization needs, you can pick from pre-built VMs at Oracle Tech Network. It supports even older Windows versions such as Windows 3.x, NT 4.0, 2000, XP, Server 2003 and Vista, making it suitable for development work among companies that continue to provide backward-compatible support for software built around these operating systems. VirtualBox runs on macOS, Windows, Linux, and Solaris hosts, and supports various guest operating systems, including Windows, DOS, Linux, Solaris and OpenSolaris, OS/2 and OpenBSD. VDI, which stands for Virtual Disk Image, is the default disk format for the open-source Oracle VM VirtualBox, an actively developed, enterprise-class virtualization product. VDI: Oracle’s Default Disk Format Used by Virtual Box VDI is the virtual disk format for Oracle VirtualBox, VHD and VHDX are designed for Microsoft’s virtualization products, and VMDK is VMware’s own virtual disk format. The more popular virtual disk formats include Virtual Disk Image (VDI), Virtual Hard Disk (VHD), and Virtual Machine Disk (VMDK). Virtual disks come in different formats, depending on what virtualization software the creator used to create them. Once a virtual machine has been installed with a virtual disk running a guest operating system, it is ready for use. In virtualization, virtual disks are where guest operating systems are installed, making them the equivalent of traditional hard disks.
