[ovirt-users] Ovirt and Shorewall

Hello All, I'm still experimenting with Ovirt-setup. Because Centos/Rhel7 now have Firewalld, and because I still have some Centos6 machines with Iptables, I was kinda hoping to use Shorewall on both. Is there any support/documentation for this in the Ovirt-world? Many thanks, J.
