KVM vs VirtualBox: What are the differences?
Developers describe KVM as "Kernel-based Virtual Machine is a full virtualization solution for Linux". KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). On the other hand, VirtualBox is detailed as "Run nearly any operating system on a single machine and to freely switch between OS instances running simultaneously". VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. Not only is VirtualBox an extremely feature rich, high performance product for enterprise customers, it is also the only professional solution that is freely available as Open Source Software under the terms of the GNU General Public License (GPL) version 2.
KVM and VirtualBox can be categorized as "Virtualization Platform" tools.

Sometimes you will need to customize your virtualbox and you can easily add virtualbox commands inside your vagrantfile
Example of USB connection Share Between Host and VM
#Use $VBoxManage list usbhost To list Usb Ports and Get Your Device VENDORID and PRODUCTID v.customize ["modifyvm", :id, "--usb", "on"] v.customize ['usbfilter', 'add', '0', '--target', :id, '--name', 'ESP', '--vendorid', '0x22b8', '--productid', '0x2e76']
Network and security programs. install and run multiple operating systems. Good to understand computer networks - internet and multiple services, such as the world wide web; and the opportunities they offer for communication (combine a variety of software and services)
We use Virtualbox in combination with Vagrant during development to ensure a consistent test/development environment. This helps to reduce the number of defects when our software goes to production.
For running a VM locally with Vagrant. It can be a little irritable, but it's open source and free, so I'm not complaining. I would probably use VMWare, but I don't want to pay for it right now.
Virtualbox is managed by Vagrant and it sets up a local development environment so that anyone can test their changes before pushing the changes upstream.
