Lance, I found some interesting logs, we have (3) oVIRT nodes. We are running: CentOS Linux release 7.2.1511 (Core) Linux hostname 3.10.0-327.36.3.el7.x86_64 #1 SMP Mon Oct 24 16:09:20 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux What is interesting now is my 2nd node now won't hand out DHCP any more, however it does have a strange "tunnel" error message on node2 also, see below. What is bizarre node1 nor node3 show that bizarre tunnel message?

Marcin,
Also I noticed in your original post it mentions:
ip link - the result should include a link called genev_sys_ ...
I noticed that on my hosts I don't see any links with name: genev_sys_ ?? Could this be a problem?

Hi Devin,
What distribution and kernel version are you using?
One thing you could check is whether the vport_geneve kernel module is being loaded, e.g. you should see something like:
$ lsmod | grep vport vport_geneve 12560 1 openvswitch 246755 5 vport_geneve
If vport_geneve is not loaded, you could "sudo modprobe vport_geneve" to make sure it's available and can be loaded.
The first 100 lines or so of ovs-vswitchd.log might have some useful information about where things are going wrong.
It does sound as though there is some issue with geneve tunnels, which would certainly explain issues with inter-node traffic.
Regards,
Lance
