[neutron][nova] Port binding fails when creating an instance
Hello, I spent a lot of time troubleshooting my issue, which I described here : https://serverfault.com/questions/1058969/cannot-create-an-instance-due-to-f... To summarize, when I want to create an instance, binding fails on compute node, the dhcp agent seems to give an ip to the VM but I have an error. I don't know where to dig, besides what I have done. Thanks a lot for your help !

As Slawek Kaplonski told me, I enabled neutron debugging and I didn't find why specific mechanism drivers are refusing to bind ports on that host. I noticed that the VM can get an IP from DHCP, I see a link on the web interface (network topology) between my physical network "provider" and the VM. But this link disappeared when the VM crashed due to the error. Here are the previous DEBUG logs, just before the ERROR one. I don't succeed in getting more informed by these logs.

I have couple of questions there: 1. What version of Neutron are You using exactly? It seems from that log that You don't have patch https://github.com/openstack/neutron/commit/74c51a2e5390f258290ee890c9218beb... in Your code. 2. What mechanism drivers do You have enabled in Your ML2 config? In logs there should be lines e.g. like https://github.com/openstack/neutron/blob/34d6fbcc2a67eac45ad6f841903f656ef7... but I don't see any line like that in Your log.

Hello,
I spent a lot of time troubleshooting my issue, which I described here :
https://serverfault.com/questions/1058969/cannot-create-an-instance-due-to-f...
To summarize, when I want to create an instance, binding fails on
compute
node, the dhcp agent seems to give an ip to the VM but I have an error.
What do You mean exactly? Failed binding of the port in Neutron? In such case nova will not boot vm so it can't get IP from DHCP.
I don't know where to dig, besides what I have done.
Please enable debug logs in neutron-server and look in its logs for the reason why it failed to bind port on specific host. Usually reason is dead L2 agent on host or mismatch in the agent's bridge mappings configuration in the agent.
Thanks a lot for your help !
