In the world of virtualization, the physical machine on which you will install VirtualBox is called the host system and its operating system is called the host operating system. In order to install and run Oracle VirtualBox, the host system and the host operating system must meet certain requirements:
Processor: Any recent Intel or AMD processor should do.
Memory: Depending on what guest operating systems you want to run, you will need at least 512 MB of RAM. Basically, you will need whatever your host operating system needs to run comfortably, plus the amount that the guest operating system needs.
Hard disk space: IDE, SATA, and SCSI hard drives are supported. VirtualBox doesn’t need much space, but you need to plan out how much the host OS needs and how much you need for the guest OS.
Optical CD-ROM and DVD
- IDE, SCSI, and SATA optical drives are supported.
- CD-ROM and DVD drives are supported.
- ISO disk image files are supported.
Supported guest operating system.
A guest OS is the operating system installed inside a virtual machine. Many operating systems are supported for use in VirtualBox, such as Windows XP, Windows 7, Windows 8, Windows Server 2008, FreeBSD, Debian, etc.
