Works in dom0:

    # xenstore-read vm
    /vm/00000000-0000-0000-0000-000000000000
    # xenstore-read /vm/00000000-0000-0000-0000-000000000000/uuid
    00000000-0000-0000-0000-000000000000

Fails in domU:

    # xenstore-read vm
    /vm/947df77a-58b5-4e3d-9b6c-aa0178d8e133
    # xenstore-read /vm/947df77a-58b5-4e3d-9b6c-aa0178d8e133/uuid
    xenstore-read: couldn't read path /vm/947df77a-58b5-4e3d-9b6c-aa0178d8e133/uuid

Please advise.
