Here are the steps involved to install VirtualBox in Kali Linux.
- Goto this link https://www.virtualbox.org/wiki/Linux_Downloads and select Debian version, either i386 or AMD64(depending upon the platform of your computer have). My system support i386. Select the location to download the file. I chose Debian 7.0 ("Wheezy") and the version of virtualbox is 4.3.2.
- Once the file is downloaded, open root terminal window and goto the downloaded directory. My default directory is /root/downloads.
- Now run, dpkg -i virtualbox-x.x.x.x~Debian~wheezy_i386.deb (where x is replaced by version of virtual box)
eg.: root@kali:~Downloads# dpkg -i virtualbox-4.3_4.3.2-90405~Debian~wheezy_i386.deb
Once we run this command, it de-compress the .deb package, start setting virtualbox environment and checks if any recent update is available.
Once setup is installed sucessfully, you can goto Applications to check if VirtualBox in listed there or not. Applications--> Systam Tools--> Oracle VM VirtualBox. Click on it to start VirtualBox.
