Open Stack

It finally works. The problem was the flag checks while looking for the 
ISO SR.

inside the find_iso_sr method (in nova/virt/xenapi/vm_utils.py), I found 
that the ISO SR must have these settings:
content type: iso
other-config:i18n-key=local-storage-iso

As far as I know, this wasn't documented anywhere. Hope this can be 
useful for people from the future.

cheers,

michaël
