ok time to see what is actually going on. Start tcpdump on the physical interfaces on both nodes:
sudo tcpdump -n -i ethX proto GRE
if the switch is blocking GRE, then you should see the DHCP request packets leave the compute node but not appear on the network node.
If you see nothing at all - take off the 'proto GRE' from tcpdump. Or try again with the crossover to see how that worked.

Yes it is, it's gre-2 and connect each other, then i restart interface on VM, but it still can't get IP from network node.
checking dnsmasq on network node is working
$ps faux | grep dnsmasq

ok good, run 'ovs-vsctl show' on both nodes. There should be gre-X port on each with remote_ip that points to the other node.
If not, check local_ip on both is correct and restart the OVS plugin agent - that should rebuild the tunnel endpoints.

networknode===========computenode Thanks! On 6/26/2013 2:55 PM, Sergey Skripnick wrote:
Sure you can use GRE tunnel on unmanaged switch.
Hello, i'm new in here
- Does vlan tagging that connected between network node and compute
node need a manageable switch?
- Can i used GRE tunnel on unmanaged switch? is that possible? or
vlan configuration on unmanage switch? so i can add more compute node.
