(Get the code!)
use_cow_images = True is only used by filesystem storage. Systems which set use_cow_images = True and use filesystem storage are not vulnerable. Everything else is vulnerable. For clarity:
nfs or local files, use_cow_images = True: not vulnerable
nfs or local files, use_cow_images = False: vulnerable
ceph, lvm, ploop: vulnerable
Essentially, anything which stores raw data is vulnerable.
