@Pilow, Well, it was a major pain, but I got both hosts on eth0 for management & eth2 for Storage10g & it's working now.
I wish XOA made this an easier process.

I ran this script to build XO on CentOS 7.
https://github.com/ronivay/XenOrchestraInstallerUpdater
It said it was successful.
systemctl says xo-server is active & running.
But when I go to it's IP address in my browser I don't get anything.
I can ping the IP address from the same PC that I'm trying to browse from.
What am I missing?
