<p style="margin: 0px; font-size: 12px; font-family: Helvetica; min-height: 14px;"><br></p>
<p style="margin: 0px; font-size: 12px; font-family: Helvetica;">I`m running neutron on ubuntu 13.10.</p>
<p style="margin: 0px; font-size: 12px; font-family: Helvetica; min-height: 14px;"><br></p>
<p style="margin: 0px; font-size: 12px; font-family: Helvetica;">And I`m having issues with VM`s getting IP through DHCP,<b> it never gets one</b>. I`m using OVS plugin.</p>
<p style="margin: 0px; font-size: 12px; font-family: Helvetica; min-height: 14px;"><br></p>
<p style="margin: 0px; font-size: 12px; font-family: Helvetica;">So, agents are up:</p>
<p style="margin: 0px; font-size: 12px; font-family: Helvetica;">+--------------------------------------+--------------------+-----------+-------+----------------+</p>

<p style="margin: 0px; font-size: 12px; font-family: Helvetica;">Network namespaces are created as well:</p>
<p style="margin: 0px; font-size: 12px; font-family: Helvetica; min-height: 14px;"><br></p>
<p style="margin: 0px; font-size: 12px; font-family: Helvetica;">root@net01-001:/etc/neutron/plugins/openvswitch# ip netns</p>
<p style="margin: 0px; font-size: 12px; font-family: Helvetica;">qrouter-33eb1c85-432f-4470-9d69-81ab09fbee28</p>

<p style="margin: 0px; font-size: 12px; font-family: Helvetica; min-height: 14px;"><br></p>
<p style="margin: 0px; font-size: 12px; font-family: Helvetica;">I can ping from qdhcp namespace the IP of router in qrouter, so those namespace can see each other.</p>
<p style="margin: 0px; font-size: 12px; font-family: Helvetica; min-height: 14px;"><br></p>
<p style="margin: 0px; font-size: 12px; font-family: Helvetica;">When I spin up a VM, i see that DHCPREQUEST packets are leaving compute node, hit the eth physical interface of network node -<b> but never get down to br-tun device</b>. I figured all that with tcpdump.</p>
<p style="margin: 0px; font-size: 12px; font-family: Helvetica; min-height: 14px;"><br></p>
<p style="margin: 0px; font-size: 12px; font-family: Helvetica;">• Also, on network node I don’t see bridges:</p>
<p style="margin: 0px; font-size: 12px; font-family: Helvetica;">root@net01-001:/etc/neutron/plugins/openvswitch# brctl show</p>
<p style="margin: 0px; font-size: 12px; font-family: Helvetica;">bridge name bridge id STP enabled interfaces</p>
