According the data from Distrowatch which based on average page hits per day for the February 2011 period, we can find the information about the popularity of the Linux distributions. The result of the three most popular distro are bellow :

Ubuntu
Ubuntu is the first popular distro linux distribution right now. This distro actually was based from Debian. Since the first release, Ubuntu is always taking its place in the top three. The popularity of ubuntu comes from the simple of installing and using this distro. The software installation and package management is fantastic easy.

Ubuntu is released twice a year in April and October.

Linux Mint
Linux Mint is the second popular linux ditribution. This distribution was based on Ubuntu with integrated multimedia codecs. The goal of this distro is to provide a more complete out-of-the-box experience by including browser plugins, media codecs, support for DVD playback, Java and other components. It also adds a custom desktop and menus, several unique configuration tools, and a web-based package installation interface. As a distro which based on Ubuntu, Linux Mint is compatible with Ubuntu software repositories.

Fedora
Fedora is the third popular Linux ditribution. Fedora is one of the community distributions sponsored by RedHat. The goal of The Fedora Project is to work with the Linux community to build a complete, general purpose operating system exclusively from open source software. The project will produce time-based releases of Fedora about 2-3 times a year, with a public release schedule. The Anaconda graphical tool allows the user to easily install and configure their system. Fedora also has the option to embed SE Linux (SE stands for Security Enhanced) during the installation which adds to an already secure system.

How to Install Virtual Box on Linux (Fedora)

This is how to get VirtualBox up and running on Linux Fedora 10.  Also, this tutorial is for the 32-Bit version of VirtualBox, so you’ll have to customize a little more to get the 64-bit version running. Everything in the “code” sections should be copy/pasted/typed into the terminal.
Right, let’s get to it:

PreStep.) Open the terminal and get into super user mode:

    su -

1.) Get the latest VirtualBox package (as of now, 2.0.6) from the VirtualBox website for Fedora 9 and install it (generally, after a few months, the Fedora 10 link will be available).

    wget http://download.virtualbox.org/virtualbox/2.0.6/VirtualBox-2.0.6_39765_fedora9-1.i386.rpm && rpm -ivh VirtualBox-2.0.6_39765_fedora9-1.i386.rpm

2.) Get the kernel-devel package:

    yum install make automake autoconf gcc kernel-devel dkms

3.) Run the setup file for VirtualBox:

    /etc/init.d/vboxdrv setup

4.) Add yourself to the “vboxusers” group and fix the SELinux Permissions:

    usermod -G vboxusers -a username
    chcon -t textrel_shlib_t /usr/lib/virtualbox/VirtualBox.so

5.) Run, and enjoy!

    VirtualBox

6.) To Get USB Support:

    1 – create a new group called “usb”;
    2 – locate file usbfs: in my case is /sys/bus/usb/drivers (I suggest to find the file with a usb device inserted;
    3 – modify file /etc/fstab inserting a line containing the right path and the number corresponding the “usb” group :
    none /sys/bus/usb/drivers usbfs devgid=503,devmode=664 0 0
    4 – command mount -a;
    5 – start VB and try…;
