virtual machine

For start you could try virtualbox.
Make shure that your system is clean using this command:

sudo apt-get purge virtualbox-*

..then run this command to ensure that system has tools for this:

sudo apt-get update && sudo apt-get install build-essential linux-headers-`uname -r`

..add the virtualbox repository to your ubuntu installation using:

echo "deb http://download.virtualbox.org/virtualbox/debian $(lsb_release -sc) contrib" | sudo tee /etc/apt/sources.list.d/virtualbox.list

..after that, add public key for apt-secure like this:

wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add -

..now you can install virtualbox

sudo apt-get update && sudo apt-get install dkms virtualbox-4.2 -y

..now just add yourself to the vboxgroup using

sudo usermod -aG vboxusers `whoami`

..reboot

Virtualbox is easy to configure and use and is available in software centre.

version in software centre isn`t the latest version available
