VMM connect problem -

[Bob Goodwin]

I have two Fedora-23 computers running 
virtual machine manager, this one 
connects to my ethernet LAN and connects 
to the internet, the second one, I've 
just set up connects to the LAN but not 
the internet, something is wrong with 
VMM configuration.

This one, the working one shows:

[bobg at localhost ~]$ ifconfig
eth0: 
flags=4163<UP,BROADCAST,RUNNING,MULTICAST> 
mtu 1500
         inet 192.168.122.30  netmask 
255.255.255.0  broadcast 192.168.122.255
         inet6 fe80::5054:ff:fe65:23a6

This is what I see in the other one that 
does not connect:

[bobg at localhost ~]$ ifconfig
eth0:

[bobg at localhost ~]$ ping -c 3 8.8.8.8
connect: Network is unreachable

I don't know what I might have done 
differently on the seond VM install, 
incidentally both are installed usingthe 
same centos 7 iso if that is of interest ...

Any suggestion of what to do next will 
be appreciated,

Bob
