Notation for Tool installation under fedora 21, centos7 OS

Dear Friends,I have installed some EDA tools under Fedora 21, and after I did all steps and invoked the tool, Soldiers refused to move, or license file cannot be started normally; finally I figured out that it's about network naming updated in Fedora OS. Same thing happened on CENTOS7.
This Error can be found by kicking:lmhostid, which will not normally return the correct MAC address of you Machine, so we have to go back to old style of network configuration in OS.just because we don't know how to change the Soldiers's mind.
Here we go...
(1) ##change "eno1" or "em1" to "eth0" : byadd net.ifnames=0 biosdevname=0 in /etc/sysconfig/grub
$vim/etc/sysconfig/grub
GRUB_CMDLINE_LINUX=”rd.lvm.lv=vg0/swapnet.ifnames=0 biosdevname=0 rd.lvm.lv=vg0/usr rhgb quiet”
(2) ## activate config
$grub2-mkconfig -o /boot/grub2/grub.cfg
(3) ## rename to ifcfg-eth0 :
$mv/etc/sysconfig/network-scripts/ifcfg-eno1/etc/sysconfig/network-scripts/ifcfg-eth0
$vim /etc/sysconfig/network-scripts/ifcfg-eth0
change item:NAME=eth0
(4) ## reboot and check:
$ ifconfig
## should list "eth0 xxxx"
(5) ##check the "lmhostid"command result agAIn.
$lmhostid
## if return the right MAC address, then we succeeded, then try to wake up your Old Soldiers .

Hope this solution help you, thanks .
