On Cloudera Training VM. Still no Oracle VM Virtual Box image available

Today I was looking at the virtual machines provided by CloudEra. I first downloaded the Virtual Box image, extracted but I discovered my Oracle VM VirtualBox Manager was not able to load it.
Look at my console:

cm1077ch@cm1077ch-pom:~$ cd VirtualBox\ VMs/
cm1077ch@cm1077ch-pom:~/VirtualBox VMs$ cd cloudera-demo-vm-cdh3u3-virtualbox
cm1077ch@cm1077ch-pom:~/VirtualBox VMs/cloudera-demo-vm-cdh3u3-virtualbox$ ll

-rw-r--r-- 1 cm1077ch cm1077ch 2574712832 2012-03-14 15:13 cloudera-demo-vm.vmdk

Where is my virtual box image ?!?!?!?

I then downloaded the VM Ware image and discovered that...

cm1077ch@cm1077ch-pom:~/VirtualBox VMs/cloudera-demo-vm-cdh3u3-virtualbox$ cd ..
cm1077ch@cm1077ch-pom:~/VirtualBox VMs$ mv ../Downloads/cloudera-demo-vm-cdh3u3-vmware.tar.gz .
cm1077ch@cm1077ch-pom:~/VirtualBox VMs$ tar xvfz cloudera-demo-vm-cdh3u3-vmware.tar.gz
cm1077ch@cm1077ch-pom:~/VirtualBox VMs$ cd cloudera-demo-vm-cdh3u3-vmware/

-rw-r--r-- 1 cm1077ch cm1077ch       1286 2012-01-30 21:47 cloudera-demo-vm.vmx

the image was the same!!!

So no Virtual Box image still is available. To convert those VM Ware iamges on a Virtual Box one simply convert one of them with the following commands:

cm1077ch@cm1077ch-pom:~/VirtualBox VMs/cloudera-demo-vm-cdh3u3-virtualbox$ pwd
/home/cm1077ch/VirtualBox VMs/cloudera-demo-vm-cdh3u3-virtualbox
cm1077ch@cm1077ch-pom:~/VirtualBox VMs/cloudera-demo-vm-cdh3u3-virtualbox$ qemu-img convert cloudera-demo-vm.vmdk /tmp/cloudera-demo-vm_raw.bin
cm1077ch@cm1077ch-pom:~/VirtualBox VMs/cloudera-demo-vm-cdh3u3-virtualbox$ VBoxManage convertdd /tmp/cloudera-demo-vm_raw.bin cloudera-demo-virtualbox.vdi
Converting from raw image file="/tmp/cloudera-demo-vm_raw.bin" to file="cloudera-demo-virtualbox.vdi"...

cm1077ch@cm1077ch-pom:~/VirtualBox VMs/cloudera-demo-vm-cdh3u3-virtualbox$
cm1077ch@cm1077ch-pom:~/VirtualBox VMs/cloudera-demo-vm-cdh3u3-virtualbox$ rm cloudera-demo-vm.vmdk 

Then create a New Virtual Machine Linux/Ubuntu with 2048 MB of RAM, check Start-up Disk and Use existing hard disk as the following images:







That's all.
