With its help, users can develop, test, demonstrate and deploy applications and features across different operating systems without needing more than one desktop. However, again, to be fair, these issues would be faced only if you go deep, but if you just run virtual OS for fun, or for simple usage, you'd have nothing to worry about.VirtualBox, developed by Oracle, is an open-source but powerful AMD64/Intel64 and x86 virtualization software.

If you use the virtual OS you're running as a main drive or you rely on it for professional purposes, this could be a total disaster as you'd face countless network issues that'd hold you back. Changing the size of disk storage could be an issue, but such issued were paid attention to with newer versions (5.2). It takes a while to come up and if your computer isn't good on the specs side, you might have a laggy and slow experience. Some features aren't supported without installing add-ons.

Some computers do not allow the installation of a Virtual Machine software without changing the BIOS, and this, of course, isn't something everyone can do.

However, if you'd like to use it more in-depth, you'd find a few issues. If you just want to test operating systems and not go in-depth, VM VirtualBox would be okay. It's not exclusive to only one operating system. It helps you test any OS in a few steps and switch between the operating systems you're running easily and swiftly. VirtualBox is open-source, easy and super fast to install and start, and it's free as well. On the personal side, I'd say almost flawless, but on the professional side, it's not what I'd rely on, but again, you get what you pay for! PROS My personal experience with it could be both satisfactory and disappointing, honestly.
