nova+quantum vm does bind ip

All,
My issue is close to what reported by Emilien and others in
https://answers.launchpad.net/quantum/+question/197701. Only difference
is that instead of not receiving DHCP reply, I do see the DHCP reply
from GW interface, but I still can not ping/ssh to the VM.
My server configuration is same as what Emilien has described in his
document here https://github.com/EmilienM, the only difference is that
I'm using a third interface (eth2) to connect quantum networks on two
servers. And the eth1 is used for management traffic.

My network configuration is
id IPv4 IPv6 start address
DNS1 DNS2 VlanID project
uuid
1 10.0.0.0/24 None 10.0.0.2
8.8.4.4 None None
61868ec0fd63486db3dbf1740e7111e9 6f765203-7fd8-425e-92b8-cf72b5c1c6cd


I launched VM in network 1 and it is running on the nova-compute server
(essex-2), I can see following tcpdump message from the tap interface
for the VM

No ARP response from the VM. I tried to login to the VM console by
virsh console instance-00000003 so that I can do tcpdump inside the VM.
But I got following error message:

root [at] openstack-:/etc/libvirt/qemu/networks# virsh console instance-00000003
Connected to domain instance-00000003
Escape character is ^]
error: internal error
/var/lib/nova/instances/instance-00000003/console.log: Cannot request
read and write flags together


Could some one suggest on how to debug this issue?
Thanks
Yi

Can you use virt-viewer to see vnc console?
