There is a known issue in 3.0.4 and lower where when a second IP Address is added it does not respond.
Rebuilding the network does not fix the issue.
In order to get the additional address to work there are a few files that will need to be removed from the vm.
rm -rf /etc/sysconfig/network-scripts/rule-eth0*
rm -rf /etc/sysconfig/network-scripts/route-eth0*
Once these files are removed reboot the vm and the IP addresses will now work.
**Please note that rebuilding the network will cause these files to be put back and will stop traffic on the additional addresses again.
This is expected to be corrected in the 3.0.5 release.
**This will work for any IPs beyond the first (2nd, 3rd, 4th, etc) that are having the same issue.
