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): kernel-3.10.0-229.el7.x86_64 openvswitch-2.1.2-2.el7_0.1.x86_64

(In reply to Kevin Fenzi from comment #4) > Might be the same as: https://bugzilla.redhat.com/show_bug.cgi?id=1200918 ? 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. Thanks.

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 openstack-neutron-openvswitch-2014.1.4-1.el7ost.noarch openvswitch-2.1.2-2.el7_0.2.x86_64 [root@puma15]# rpm -qa | grep neutron openstack-neutron-openvswitch-2014.1.4-1.el7ost.noarch openstack-neutron-2014.1.4-1.el7ost.noarch python-neutronclient-2.3.4-3.el7ost.noarch openstack-neutron-ml2-2014.1.4-1.el7ost.noarch python-neutron-2014.1.4-1.el7ost.noarch [root@puma15]# rpm -qa | grep kernel kernel-3.10.0-229.el7.x86_64 abrt-addon-kerneloops-2.1.11-19.el7.x86_64 kernel-tools-3.10.0-229.el7.x86_64 erlang-kernel-R16B-03.7min.1.el7ost.x86_64 kernel-tools-libs-3.10.0-229.el7.x86_64
