Virtual Box versions for:
-- Windows 7/8/10
-- All Linux installations
-- MAC OS x
-- Solaris 10/11
Virtual OSs include:
-- Oracle Linux 5/6/7.x (RHEL clones)
-- Occassionally a Windows Beta
Oracle itself provides many free VMs, pre-configured with various software stacks and hands-on lab materials for learning, geared toward. These have helped me earn three of my Oracle certifications:
-- Oracle Database development
-- Oracle DBA
-- MySQL development
-- Java Standard/Enterprise development
-- Big data
-- Webcenter portal & others
Pre-installed software in or more of the various stacks includes:
-- Oracle Database 11/12
-- Enterprise Mgr
-- Cloudera, etc.
Pro Supports modern shells
Whether you prefer zsh, bash, or fish, Linux will support it.
Pro Isolated from Windows
VirtualBox provides almost total isolation from Windows running underneath it, removing a lot of security issues.
Pro Free / Libre Software
While the OS underneath it is proprietary and does spy on you or actively violate your freedom, so to speak, you can still have a little piece of mind knowing that VirtualBox (your Linux distro and shell of choice) as well as Terminator are all FOSS.
Con Not free
The subscription costs $89 per year.
Con No stable portable version
Any portable version present is wrapper. It moves files from portable folder to appdata and backward, which often cause dataloss
Con Install a whole operating system for one program
You would need to install the entire Linux distribution just for one single program.
Con Slightly slower than just running Linux
The Windows + VirtualBox layer introduces some overhead that wouldn't be present if Linux were installed directly on the machine.
