Hi dinesh,

d->handle contains the domain uuid.

A uuid is a 16 byte number. Xen and libuuid store uuids as 16 byte
char array. They both define typedefs (xen_domain_handle_t and uuid_t
respectively)  for a 16 byte char array.

If you want to generate a human readable version, you can use
uuid_unparse to generate a 37 character C string from the uuid_t.

Hope this helps.
