Absolulty. Thanks.
but uuid_unparse() is defined in /usr/include/uuid which means I could use this only from the use space in domain-0.
The hypervisor doesnot include these user space libraries. How could I convery the dmain->handle; the 16 byte uuid to a human readable
from inside the hypervisor?
thanks,
