1. edit eth0's xml, don't do any other thing in this step

  # virsh iface-edit eth0

2. dump the xml of eth0 via ncftool (if it doesn't exist, install netcf)

  # ncftool
  ncftool> dumpxml eth0

3. get the configuration of eth0 via augtool (if it doesn't exist, install augeas)

  # augtool
  augtool> print /files/etc/sysconfig/network-scripts/ifcfg-eth0

4. # cat /etc/sysconfig/network-scripts/ifcfg-eth0

5. compare the result of step 1, step 2, step 3, step 4, with each other. check if the informations are consistent. checkpoints:

   1> if something is missed
   2> if something's value if not consistent

6. save the config file of eth0

   # cp /etc/sysconfig/network-scripts/ifcfg-eth0 /tmp/

7. change something via "virsh iface-edit", and save it. such as delete the "<dhcp/>"

8. restart the network

  # service network restart

9. check whether the eth0 has IPv4 address

   # /sbin/ifconfig

10. loop the upper steps with passing MAC address but not interface name to "iface-edit"


1. restore the config file of eth0

  # cp /tmp/ifcfg-eth0 /etc/sysconfig/network-scripts/

2. restart network

  # service network restart

Expected Results:

Step 5:

     checkpoints are passed

Step 6:

     successfully changed

Step 8:

      eth0 will not has IPv4 address
