VirtualBox

Pros

With VirtualBox, I easily create a test and dev environment for different OS, it supports all type of OS from Window, Ubuntu, Centos. VirtualBox Guest system is quickly created and start and I could share data between Host OS and Guest OS including copy/paste, disk sharing and drag-drop. VirtualBox consume very little resource and is able to host multiple Guest OS at same time, it is an excellent feature when we want to test our script in different OS

Cons

Using VirtualBox is quite complex to setup Guest OS, special to enable access to Host OS hardware such as Printer, switch between Host OS and Guest OS have delayed time

Pros

Have been using VirtualBox to spam new distributions of linux and other open source operating systems and also use Virtual box to deploy our application as well and we use it as a benchmarking mechanism tool.

Cons

The least thing we like about this is the amount of compute it takes to run the application on the slight less specked machine and it does a take on the battery life, otherwise the application is good.

Pros

I am using this software since 2008. It is light weight Virtualization Software available on market. It is easy to setup and works easily without any glitches. Using this Software to check the operating of website on different Operating Systems. Using this to works on developing cross platform applications.

Cons

Well it works great but unlike VMWare VSphere. It only works on one machine and not providing any remote access to operate virtual machines on network.

Pros

VirtualBox is open-source, easy and super fast to install and start, and it's free as well. It helps you test any OS in a few steps and switch between the operating systems you're running easily and swiftly. It's not exclusive to only one operating system.

Cons

If you just want to test operating systems and not go in-depth, VM VirtualBox would be okay. However, if you'd like to use it more in-depth, you'd find a few issues. 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. Some features aren't supported without installing add-ons. Also, sound drivers aren't available. 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. Changing the size of disk storage could be an issue, but such issued were paid attention to with newer versions (5.2). 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. 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.

Pros

This software does a pretty good job with virtualizing both Linux and Windows guest VMs inside of your desktop environment. It makes spinning up new systems and testing them out relatively easy, and the built-in network features make it straightforward when deciding what VLAN or network type you would like your VM to be running on.

Cons

Performance appears to be a bit slower than using VMWare Workstation Pro. Additionally, the documentation on Oracle's site is nowhere as comprehensive as that of VMWare or Microsoft. Finally, there is a longstanding issue with CredentialGuard and Windows 10 which requires that certain security precautions be disabled in order for VirtualBox to operate. While this has *finally* been solved in VMWare Workstation, this is still a rather significant issue in VirtualBox which is a detriment to its use.
