Fixed In Version: openvswitch-2.1.2-2.el7_0.2
Doc Type: Bug Fix
Doc Text:
Prior to this update, an incompatibility issue in 'openvswitch-2.1.2-2.el7_0.1' with the Red Hat Enterprise Linux 7.1 kernel resulted in 'ovs-vswitchd' crashing. This update addresses this issue by backporting the fix from upstream. As a result, correct operation can be expected with 'openvswitch' on Red Hat Enterprise Linux 7.1 kernels.

Description Marko Myllynen 2015-03-12 17:55:26 UTC
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.

Comment 7 Lon Hohberger 2015-03-25 17:13:48 UTC
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

Comment 8 Lon Hohberger 2015-03-25 17:16:54 UTC
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.

Comment 10 Eran Kuris 2015-03-30 08:10:27 UTC
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
