[one-users] OpenNebula and OVA files support

[Alvaro Simon]

Hi Jaime, Carlo

We have also tried this script but the dd command in our case fails 
using these options "conv=notrunc oflag=seek_bytes", so finally we have 
downloaded the latest qemu source code from github [1] and we have 
compiled it. The new version is now patched and it works fine with VMKD3 
images :-) and we don't need to install virtualbox package.

The new compiled qemu-img binary is now available from our frontend to 
convert our images and we don't need to change Jamie's code :-)
