[Message part 1 (text/plain, inline)]

Hi, as suggested by Josselin, I tested the following patch and it seems 
to do the job here.


Be careful, I'm not an udev or lvm2 specialist at all and basically, I 
don't really know if what I did is the right way to do it.


All I can say is that the VMs now boot.


Cheers,
