% man ipv6 

   Address Format
           struct sockaddr_in6 {
               sa_family_t     sin6_family;   /* AF_INET6 */
               in_port_t       sin6_port;     /* port number */
               uint32_t        sin6_flowinfo; /* IPv6 flow information */
               struct in6_addr sin6_addr;     /* IPv6 address */
               uint32_t        sin6_scope_id; /* Scope ID (new in 2.4) */
           };

           struct in6_addr {
               unsigned char   s6_addr[16];   /* IPv6 address */
           };

% vim libvirt/src/util/network.c

 43 static int getIPv6Addr(virSocketAddrPtr addr, virIPv6AddrPtr tab) {
 44     int i;
 45 
 46     if ((addr == NULL) || (tab == NULL) || (addr->stor.ss_family != AF_INET6    ))  
 47         return(-1);
 48 
 49     for (i = 0;i < 8;i++) {
 50         (*tab)[i] = ntohs(addr->inet6.sin6_addr.s6_addr16[i]);
 51     }
 52 
 53     return(0);
 54 }

I guess it's a typo, should be "addr->inet6.sin6_addr.s6_addr[i]", but not 
"addr->inet6.sin6_addr.s6_addr16[i]".. :-)
