Yes, I've put the server restart. but no effect, is normal before. Have a problem because I installed the CEPH found CEPH and CENTOS KERNEL of 6.5 is not compatible, so the KERNEL was updated to 3.0. But after updating KERNEL 3.0, the kernel cannot support OPENVSWITCH GRE. So I chose to return to the start when the CENTOS KERNEL 2.6 a failure now
