I am installing Kilo from scratch. When I get to the step in networking (the end) where I enter the command: neutron agent-list I get nothing in return a few millisecond pause and then the command prompt returns.

Is there a debugging or tracing mechanism for me to see what is going wrong? Thank You Foexle for the --debug.

This is my return from that command:

ivar@controller:~$ neutron --debug agent-list

Does anyone have an opinion on why I have no agents? I also wonder why my network machine runs so hot - dual core and over 60% proc utilization. neutron-openvsw, neutron-l3-agen and neutron-dhcp-agen are the top processes - but maybe thats normal.

Further research: I am running a KVM host (2-quad cores 32GB RAM) that is hosting my controller and network nodes in VMs. I found that the processor load is due to the log files growing at a huge velocity. Almost every neutron log on the network node is constantly logging variations of:

This was user stupidity. I forgot to install the base Ubuntu cloud package on the node. I apt-get installed it and it worked fine. Sorry and thanks for the help

Hi Ivarh,

it could be your Neutron API is taking some time to get all informations. That could be some reasons, slow database, slow keystone, slow API ...

You can enable verbose, so debug, output for each OpenStack client with the option --debug, in your case:

neutron --debug agent-list

Cheers Heiko

So, it seems to be Keystone is working. So we should take a look on other places:

  • Check all neutron logs (DB connection problems; RabbitMQ problems)

How many servers do you have ? You have separate servers for network and controller (API) ?

I added some log info above in problem
