Hi,
Please can you look up in the iptables?
Normally on a working openstack host the packets comming in the filter table in
the input chain are directed to the nova-network-INPUT which has a rule to
accept dhcp packets.
On my setup is something like:
-A INPUT -j nova-network-INPUT
.
.
.
-A nova-network-INPUT -i br100 -p udp -m udp --dport 67 -j ACCEPT
So I think you have to look somewhere else for your issue.
Regards,
Gabriel

Subject: [Openstack] [Quantum/Neutron] VM cannot get IP address from DHCP server
Hi,
We are running OpenStack Folsom on CentOS 6.4.
Quantum-linuxbridge-agent is used.
By default, the Quantum node has the following entries in its
/etc/sysconfig/iptables file.
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
With those two lines, VM cannot get IP address from the DHCP server running on
the Quantum node.
More specifically, the first line prevents a VM from getting IP address from
DHCP server.
The second line prevents a VM from talking to other VMs and external worlds.
Is there a better way to make the Quantum network work well
than just commenting them out?
I'll appreciate your help.
David
