In this post, we will put together a headless installation of VirtualBox, the VirtualBox web services and a we will install phpVirtualBox on RedHat.


Oracle provides a repository but the servers were so slow that I had to download directly the rpm file from the download page. That’s a pity, i’ll have to deal with the updates myself. Anyway, make sure you download the right rpm: Oracle Linux 6 ("OL6") / Red Hat Enterprise Linux 6 ("RHEL6") / CentOS 6 *AMD64* in my case.

yum install VirtualBox-4.3-4.3.2_90405_el6-1.x86_64.rpm

Now you have to setup the kernel module. To do so, you’ll need to have some dependencies installed

yum install kernel-devel dkms

Having your system updated will help avoiding troubles.  Now for the real thing:

service vboxdrv setup

If compilation fails, make sure the kernel version your are running correspond to the latest version installed on your system. Such a discrepancy can occur if you have updated your kernel but have not restarted the server yet.

VirtualBox Extension Pack

Given our current target, you might be interested in the features offered by the extension pack:

  • VirtualBox RDP
  • PXE boot for Intel cards

If you are not interested you can skip this section. Else, download the pack from the download page and push it to your server or


Then install it

VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.3.2-90405.vbox-extpack

Note: this command will fail if an older version of the same extension pack is already installed. The optional –replace parameter can be used to uninstall the old package before the new package is installed. See manual.

VirtualBox Web Service

If you try to start the webservice at this point, you be very disappointed: it won’t start and won’t give any explanation. Looking at the startup script /etc/init.d/vboxweb-service, I found the source of this behavior:

[ -z "$VBOXWEB_USER" ] && exit 0

The script being fairly organized, one can easily understand this variable is supposed to be defined in /etc/vbox/vbox.cfg.

Create a user, set its password and edit vbox.cfg:

useradd -g vboxusers -N vboxws
passwd vboxws
mkdir /etc/vbox/
echo "VBOXWEB_USER=vboxws" >> /etc/vbox/vbox.cfg

Now you can (re)start the service

service vboxweb-service restart


I’ll assume you’ve already set up a running web server that serves files from /var/www/html/ and have PHP enabled.

Download the archive from SourceForge. Be careful to download the version corresponding to your version of Virtualbox.

mkdir /var/www/html/phpvirtualbox
cd /var/www/html/phpvirtualbox
cp config.php-example config.php
sed -i "s/$username = 'vbox'/$username = 'vboxws'/" config.php
sed -i "s/$password= 'pass'/$password= 'my-password'/" config.php

phpVirtualBox required the PHP SOAP module.

yum install php-soap

Now, using your browser, you can connect to phpVirtualBox. The default login/password is admin/admin.
