I "tested" it on 4 VMs.. The performance was crap as expected, but wanted to 
see how it behaves when I suddenly remove a node from the setup and so on.
(it went well, the setup froze for a second but after that kept working at 
normal parameters)

No, I should've rephrased this, I meant the likes of raid10, of course, in 
Glusterfs "speak". Basically I had 2 pairs of replicated nodes and files 
stripped across all this.
I even ran a VM on top of this VM based glusterfs setup.. not the speediest 
VM, but was usable. :-)
