Hi Damon,<br>
<br>
I did some investigation on this issue and have current updates here. The<br>
actual issue I feel is with the iptables. When I stopped the iptables<br>
service on the compute, the dnsmasq service started for the private flat<br>
network. Then my VM got the IP from the flat network subnet pool correctly.<br>
<br>
Some observations:<br>
(1) While loading the VM I see some error messages where it fails to<br>
connect to the metadata due to network not reachable.<br>
(2) When I assign the public floating IP to my VM, I cannot ping the<br>
floating IP from my compute or controller and even from the VM I cannot<br>
ping any external IP.<br>
<br>
Some screen shots:<br>
(1) nova list on controller:<br>
(Embedded image moved to file: pic04247.gif)<br>
<br>
(2) ovs-vsctl show on compute:<br>
(Embedded image moved to file: pic27494.gif)<br>
<br>
(3) cat /etc/sysconfig/iptables output<br>
(Embedded image moved to file: pic11300.gif)<br>
<br>
I believe now we have narrowed down this issue where the iptables needs to<br>
be corrected so we do these operations with iptables service running and<br>
also able to connect to the VM from the floating IPs.<br>
Hope this data helps you for further analysis.<br>
<br>
Regards,<br>
Akash<br>

Hi Damon,<br>
<br>
Here is the data of /var/log/messages from my compute node.<br>
<br>
(1) First I created a flat network and deployed a VM but I did not see the<br>
DHCPREQUEST or DHCPACK logs. The private IP was not assigned on the actual<br>
VM but it was seen on the controller against the VM.<br>
<br>
(2) Second, I created a vlan network with a dummy segmentation_id 60 and<br>
below logs are seen in messages log file. Even the private IP got assigned<br>
on the VM correctly. But this IP assignment happens only when my compute<br>
node iptables service is stopped.<br>
<br>

After my exercise with vlan, I created a external network of type local and<br>
using router I assigned a public IP to the VM which was created using<br>
private VLAN network. I was only able to ping the public IP from controller<br>
but not<br>
from compute. I tried to ping an external IP from the VM but it failed.<br>
<br>
With VLAN network I am able to proceed a little but with flat network its<br>
still blocked. I want to create a VM with private flat network and then<br>
assign the public IP using external network for providing internet access<br>
to the VM.<br>
<br>
Additional info:<br>
(1) Compute node has RHEL 6.5 KVM<br>
(2) The VM is deployed using Centos 6.5 image.<br>
(3) The controller is hosted on RHEL 6.5<br>
<br>

Hi Akash,<br>
<br>
Can you paste your log of /etc/message, normally, you'll see something like<br>
this:<br>
<br>
"Apr 27 09:21:48 gd60 dnsmasq-dhcp[8872]: DHCPREQUEST(tapce4121ff-d6)<br>
192.168.220.6 fa:16:3e:21:1f:58<br>
"Apr 27 09:21:48 gd60 dnsmasq-dhcp[8872]: DHCPACK(tapce4121ff-d6)<br>
192.168.220.6 fa:16:3e:21:1f:58 host-192-168-220-6<br>
"Apr 27 21:21:48 gd60 dnsmasq-dhcp[8872]: DHCPREQUEST(tapce4121ff-d6)<br>
192.168.220.6 fa:16:3e:21:1f:58<br>
"Apr 27 21:21:48 gd60 dnsmasq-dhcp[8872]: DHCPACK(tapce4121ff-d6)<br>
192.168.220.6 fa:16:3e:21:1f:58 host-192-168-220-6"<br>
<br>
Besides, try to check iptables, you can use raw table to trace data path in<br>
iptables.<br>
<br>
Hope it helps,<br>

Hello,<br>
<br>
I am using icehouse version for doing my network setup using openvSwitch<br>
agent with ML2 plugin. I want to configure flat network with DHCP server<br>
so<br>
the IP gets assigned to the guest VMs after deployment. As part of this I<br>
have started the dhcp and openvSwitch agents on my compute node and<br>
created<br>
a flat private network and deployed the virtual machine on the compute.<br>
The<br>
VM gets deployed but it fails to get the IP from the controller even<br>
though<br>
I see the IP assigned on the controller for that VM.<br>
<br>
I see an error message on the VM boot up stating that its cannot connect<br>
to<br>
169.254.169.254<br>
<br>
I see the dnsmasq process running on my compute node. Please point me to<br>
the error here and if my dhcp setup is correct.<br>
<br>
Regards,<br>
Akash<br>
