Description of problem:
Installing latest RHEL OSP 5 on RHEL 7.0 works fine but when doing the same installation on RHEL 7.1, the ctrl/network node is unreachable, it turns out that ovs-vswitchd crashes on startup everytime with RHEL 7.1 kernel (-229). After rebooting the same OSP5/RHEL7.1 installation with RHEL 7.0 kernel (-123) there are no crashes and networking works as expected.
I have no more access to the lab where this was seen but I will attach a core dump from one of the crashes.
Version-Release number of selected component (if applicable):

Yes, very likely so, but since the RDO fix was just to upgrade to 2.3 there doesn't seem to be any detailed analysis of this at least in the RHBZ.
*** Bug 1205215 has been marked as a duplicate of this bug. ***
There's a known issue on 7.1 kernels with openvswitch 2.1.2. This is fixed in RHEL OSP 6, and is likely the same issue here.
The OSP 6 bug is bug 1185521
openvswitch-2.1.2-2.el7_0.2 will need to be added to RHEL OSP 5 to resolve this; the openvswitch-2.1.2-2.el7_0.1 package is the one which exhibits the issue.
The bug verified on OSP-5 with OS- rhel 7.1
there is no crashes , I tried to stop & start openvswitch service to verify the
beehive of it.
I created network with few instances on 2 compute nodes , I got full connectivity include using floating IP .
The version that verified :
# rpm -qa | grep openvswitch
[root@puma15]# rpm -qa | grep neutron
[root@puma15]# rpm -qa | grep kernel
