Nothing obvious.  Since your interfaces have static configurations, I'd 
suggest turning off NetworkManager and turning on the "network"
service
to determine whether or not that works correctly after a reboot.

Assuming it does, fixing the issue might be as simple as getting 
NetworkManager to not rename one interface to "wired connection 1".

Hello Gordon

Thank you for your response.  I disabled NetworkManager and started the
network service, then I rebooted the VM and now 'ip rule show' has the
rules for both interfaces showing but I have no network connectivity even
when I restart the network service.  Should I reenable NetworkManager now?
How would I go about getting NetworkManager to stop creating new Interface
files and naming them Wired_connection-*?


Thanks!

Yeah, the switch is just a test to see if the problem is specific to 
NetworkManager.  It seems that you have other problems as well.

Before you do that, post the output of the following:

ip route show

ip route show table 300

ip route show table 301

ip rule show

cat /etc/sysconfig/network-scripts/ifcfg-eth0

cat /etc/sysconfig/network-scripts/route-eth0

cat /etc/sysconfig/network-scripts/rule-eth0

cat /etc/sysconfig/network-scripts/ifcfg-eth1

cat /etc/sysconfig/network-scripts/route-eth1

cat /etc/sysconfig/network-scripts/rule-eth1
