Newly added virtual Network to a RHEL-VM using RHEVM was not showing in ifconfig command
==================================================================
ifconfig command was showing only eth0 adn loopback interface

Check for ethtool eth0


[root@testvm1 ~]# ethtool eth0
Settings for eth0:
        Link detected: yes


[root@testvm1 ~]# ethtool eth1
Settings for eth1:
        Link detected: yes


but in ifconfig it is showing only

[root@testvm1 ~]# ifconfig

Solution:

  create a new configuration file for eth1 (ifcfg-eth1)

then restart the service

#service network restart
