RHEV (ovirt) supporting RHEL 7 LXC hosts.

Do we know if you can run LXC guests in LXC RHEL 7 vms under RHEV? I'm running older debian squeeze vservers without issue in VM's on RHEV.
RHEL7 LXC guests appear to have networking issues in RHEV.

I have RHEL7 LXC vm's running fine KVM, but RHEV (ovirt) doesnt work. But I cant find any info why it shouldnt work, or if supported either way.

Thought it might be the IPtables default install. Maybe its a bug, but documenation is lacking.
