<div class="moz-cite-prefix">You should be close to the solution.
Looking at your GRE tunnels, I only see a one-to-one tunnel in
between your compute node and your network node (provided your
netnode is 10.10.10.1). Could you please confirm that your
controller is either on the compute node or on the network node
?<br>
<br>
One could suggest to restart nova-compute and check.<br>
Also, could you please tcpdump your network node on your
management IP and check if you see GRE packets coming from your
compute node (while pinging or trying to get a lease) ?<br>

and they did not get IPs. Brought one up manually and could
not ping anything else. I note that I'm missing the "tag"
statement on those recreated interfaces in "ovs-vsctl show",
so I deleted the interfaces and reran the statements you gave
with "tag=1" appended. Now, my manually configured 10.5.5.5
COULD ping my working 10.5.5.7, and I could ssh between the
two. However, 10.5.5.5 still can not get a DHCP address or
(with hardcoded IP) reach 10.5.5.1 on the network node,
whereas 10.5.5.7 can. Here's how things look now:<br>

<div>You get it. This is the bug I mentioned related
to compute nodes. Folks, anyone knowing the bug
tracking numbre, btw ?<br>
<br>
'ovs-dpctl show' shows you that only qvo7dcd14b3-70
is bridged to br-int (and mapped to vnet4, which I
guess is the vnet device for the correct VM).<br>
<br>
Could you please try :<br>
sudo ovs-vsctl add-port br-int qvo0b459c65-a0<br>
sudo ovs-vsctl add-port br-int qvo4f36c3ea-5c<br>
sudo ovs-vsctl add-port br-int qvo62721ee8-08<br>
sudo ovs-vsctl add-port br-int qvocf833d2a-9e<br>
sudo service quantum-plugin-openvswitch-agent
restart<br>
<br>
and check that your VMs get network back ?<br>
