Routing Issue on KVM Server
I installed a new KVM *slave* node in SolusVM using Centos 6.6 as the host O/S.
I routed a /29 as primary on my Cisco switch and a /24 subnet as secondary.
Problem is, the /24 is not pinging or working except on the gateway and .2 IP. I'm 100% confident they're routed at the switch fine too. Solusvm support sucks, they're not helping out at all.
Results:
Code:

The /29 works fine, but the /24 doesn't.
