No lease, failing</pre><pre style="white-space:pre-wrap;word-wrap:break-word"><br></pre><pre style="white-space:pre-wrap;word-wrap:break-word">So this says that you didn't get DHCP response for your DHCP request and hence your VM didn't get any ip address assigned.</pre>
<pre style="white-space:pre-wrap;word-wrap:break-word">I think as a next step of debugging, you need to check whether your DHCP request packet is reaching to the DHCP or not? Dump the packets at the networking node and check if you get any DHCP request packet. If you are using openvswitch plugin with VLAN then make sure that your switch ports are trunked and it allows traffic from all vlans.</pre>
