CentOS - Aug 2014 - CentOS7 Minimal installation on Vmware missing network interface

Hi there, I'm playing with CentOS 7 (don't know if it's recommended
at all
have this one as a development server as maybe is not stable enough yet)
and I installed it on a Vmware VM with two network interfaces: one as a
bridged connected directly to the physical network and replicating the
network state and the second one as a host only interface (the one I use to
manage the VM) so after I got the CentOS installed I can see the first
interface but not the second one and I don't know how to enable it. If I
run the command ifconfig -a this is what I see:

eno16777728: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.1.112  netmask 255.255.255.0  broadcast 192.168.1.255
        inet6 fe80::250:56ff:fe2e:e245  prefixlen 64  scopeid 0x20<link>
        ether 00:50:56:2e:e2:45  txqueuelen 1000  (Ethernet)

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>

        TX packets 8  bytes 552 (552.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

What I need to do in order to enable the other interface? Also how I change
the name eno16777728 to eth0-internet without get down my server?

Thanks in advace

This is something of a loaded question and also quite dependent on what 
you are doing. If the server is very critical, I would probably wait 
until 7.1 or 7.2. If the server is not very critical, then sure, use EL7 
and start learning it (and report bugs! :) ).

If 'ifconfig -a' doesn't see it, the kernel probably doesn't,
either. Do
you see it in lspci or dmidecode? If not, I would look at the hypervisor 
for a problem.

Yes you can do it without rebooting, but it still requires taking the 
network down.

I wrote this a while ago:

https://alteeve.ca/w/Changing_Ethernet_Device_Names_in_EL7_and_Fedora_15%2B

It probably needs to be updated/cleaned up, but it should be good enough 
to help you.
