Here is the small guide to setup phpVirtualBox on Ubuntu (Its supports all Linux Variants, its minimum requirement is to have the web server installed with PHP support).
Prerequisites:
Install Apache with PHP.sudo apt-get install apache2 php5 libapache2-mod-php5
Download phpVirtualBox:
Issue the following command to download the lastest phpVirtualBox.wget 'http://sourceforge.net/projects/phpvirtualbox/files/latest/download'
Extract it.sudo unzip phpvirtualbox-*.zip
Move it to default document root of web server.sudo mv phpvirtualbox-* /var/www/html/virtualbox
Configure phpVirtualBox:
We need to modify the phpVirtualBox configuration to make the successful communication with VirtualBox installation, first we need to rename sample config file (config.php-example to config.php).sudo mv /var/www/html/virtualbox/config.php-example /var/www/html/virtualbox/config.php
Modify the config filesudo nano /var/www/html/virtualbox/config.php
Following are the minimum configuration for phpVirtualBox. User Name /
Password for the system that runs VirtualBox, in my case i am using
user “raj”, because he will be configured to run vboxwebsrv service(
will be set in next step).var $password = ‘x’;
Configure vboxweb-service:
VirtualBox setup creates init script vboxweb-service when it is installed, this is used to start and stop the vboxwebserv, before starting the service, we need to have /etc/default/virtualbox file because it contains settings for the service . We need to create it manually if it does not exists.sodo nano /etc/default/virtualbox
We must set minimum VBOXWEB_USER to run the vboxweb-service, now
VirtualBox will run as “raj”; this user and password must be entered in
phpVirtualBox config file.VBOXWEB_USER=raj
If you are running phpVirtualBox in some other host, VBOXWEB_HOST is
need to be set in the same file, in this case phpVirtualBox will
communicate with vboxweb-service over the network.VBOXWEB_USER=raj
VBOXWEB_HOST=192.168.1.103
Restart the vboxweb-service.sudo /etc/init.d/vboxweb-service restart
Now open a web browser and point to http://your-ip-address/virtualbox, you will be asked to login. Default login is admin /admin.

You can take console by clicking console tab in browser.

Take mstsc of host server where VirtualBox is running.
