Title:
VXLAN kernel requirement check for openvswitch agent is not working
Status in OpenStack Neutron (virtual network service):
Fix Released
Bug description:
on RHEL7 beta agent set to use VXLAN tunneling does not start.
I'm using rdo packages, if you want I can check the upstream version
somewhere, but seems that code that checks the version is still in github.
in openvswitch-agent.log I see:

It seems that the minimum kernel version required to use VXLAN is set
to 3.13 (shouldn't 3.9 be enough ?). RHEL7 ships only 3.10. Vxlan
module however is present and working, and even if the only module
properly working is in 3.13 kernel, the check doesn't take into
consideration backported features.
