Hi,Bharata B Rao:
       I have try your patch, but has some problem. I found that both
glusterfs and qemu have a fun uuid_is_null.
glusterfs use contrib/uuid/isnull.c
qemu use block/vdi.c


I test the api/example, the glfsxmp.c call uuid_is_null in
contrib/uuid/isnull.c
but qemu/block/gluster.c finally call the uuid_is_null in vdi.c which cause
vm can't boot.

I was wonder why this happen?


Best Regards,
yin.yin
