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. >________________________________ > From: Mahardhika <[email protected]> >To: Darragh O'Reilly <[email protected]>; Sergey Skripnick ><[email protected]>; "[email protected]" ><[email protected]> >Sent: Wednesday, 26 June 2013, 12:39 >Subject: Re: [Openstack] Vlan or Gre on Switch > > > >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 >============ > dnsmasq --no-hosts --no-resolv --strict-order --bind-interfaces --interface=tap1a8f1ea3-54 --except-interface=lo --pid-file=/var/lib/quantum/dhcp/5b4619d2-198b-453a-8ab6-b1c5545edb1f/pid --dhcp-hostsfile=/var/lib/quantum/dhcp/5b4619d2-198b-453a-8ab6-b1c5545edb1f/host --dhcp-optsfile=/var/lib/quantum/dhcp/5b4619d2-198b-453a-8ab6-b1c5545edb1f/opts --dhcp-script=/usr/bin/quantum-dhcp-agent-dnsmasq-lease-update --leasefile-ro --dhcp-range=set:tag0,10.10.30.0,static,120s --conf-file= --domain=openstacklocal >============ >On 6/26/2013 5:02 PM, Darragh O'Reilly wrote: > >ok good, run 'ovs-vsctl show' on both nodes.

If not, check local_ip on both is correct and restart the OVS plugin agent - that should rebuild the tunnel endpoints. >>________________________________ From: Mahardhika <[email protected]> To: Darragh O'Reilly <[email protected]>; Sergey Skripnick <[email protected]>; "[email protected]" <[email protected]> Sent: Wednesday, 26 June 2013, 10:44 Subject: Re: [Openstack] Vlan or Gre on Switch Sure it is, but it's on vlan configuration, i am working on tunnel now.
