Can you describe more precisely what you've tried so far? It seems as if the interfaces eth0 and eth1 are down, so have you tried to get them up?
In a second terminal session run
tail -F /var/log/messages
and then see what happens when you execute
ifup eth0
in the first session. You can paste the output here, make sure to remove any sensitive data.

It also looks as if your network devices are renamed, probably because of udev rules:
[ 23.464965] ibmveth 30000002 eth3: renamed from eth0
Check /etc/udev/rules.d/70-persistent-net.rules for anything you find strange or delete the entries if not needed, after making a backup copy of that file, of course. After cleaning up the udev rules I would reboot the VM to see the results.
