Description Majid Azimi 2012-08-12 06:15:38 UTC 
Description of problem:

OSSP uuid package fail to generate UUID based on global mac address if the name of interface is not "eth0". it falls back to local multicast mode. the source of uuid_mac.c include:

    if ((s = socket(PF_INET, SOCK_DGRAM, 0)) < 0)
        return FALSE;
    sprintf(ifr.ifr_name, "eth0");
    if (ioctl(s, SIOCGIFHWADDR, &ifr) < 0) {
        close(s);
        return FALSE;
    }

As you see if the interface name is not eth0(mine is p4p1 on fedora 17 generated by NetworkManager) it will fail.
