[Resolved]No output packets from OVS
Hi,
i use RDO Icehouse (last version) on Centos 6.4. My compute use a vcenter hypervisor for VM. I use neutron in VLAN mode.
My problem is that no packets coming from my network interface (ETH1). DHCP listen all traffic from his vlan but when it send a packets (e.g ARP REQUEST), the packet stop on physical interface.
EDIT : When i create a interface vlan with vconfig on br-int doesn't works. But if I create on ETH1 it works.

You didn't create any neutron router.
ip netns
doesn't show any qrouter-namespace.There is no qg-xxxxxxxxx interface attached to br-ex.
I remove qrouter from ip netns for best read.
