Resize a Fedora .vdi file in Oracle VM VirtualBox 4.1.8

The LVM system file used by Fedora is not supported by GParted.
In order to add the new volume to the existing partition, we need to use system-config-lvm.

sudo yum -y install system-config-lvm

French article describing how to proceed. NB: If meeting the following error:

process 702: D-Bus library appears to be incorrectly set up; failed to read 
machine uuid: Failed to open "/var/lib/dbus/machine-id": No such file or directory.

Then run the following command as root.

> dbus-uuidgen > /var/lib/dbus/machine-id
