ovs-vswitchd crashing continuously on reboot of network node

Hi,

I recently finished the first phase of a 4 node OpenStack (Juno) lab on CentOS 7 using the guide found here:

http://docs.openstack.org/juno/install-guide/install/yum/content/ch_preface.html (http://docs.openstack.org/juno/instal...)

On the whole this went pretty smoothly and I was able to launch instances and ping the l3 agent router IPs etc. I'm running into an external issue that necessitates that I reboot my network node and am finding that after it comes back up, my instances are no longer able to leverage any network node services any longer (dhcp and l3 are now inaccessible).

I noticed that ovs-vswitchd seems to be crashing and respawning constantly after the reboot with messages to this effect:

You are running OVS 2.1.3 on CentOS 7. Please,view https://bugzilla.redhat.com/show_bug....
If this a case, it might be fixed now just via yum update to OVS 2.3.1 . It is 100% bug on CentOS 7.1
Kernel 3.10.0-229.1.2.el7.x86_64 doesn't work with OVS 2.1.3.
