Hello there!

Do you know if nova-network is running and if it is logging any errors?

I am just a beginner with OpenStack, but you'll be able to get a lot more traction figuring out your problem if you check those two things.

To check if nova-network is running, use nova-manage service list and look for nova-network there. If it has a happy face ':-)' it started properly, otherwise it will show 'XXX' meaning it couldn't start for some reason.

Also look at the end of the nova-network log file, which is /var/log/nova/nova-network.log. If nova-network is not running then the log will probably have errors that point out why; if it IS running then try running your nova network-create command again and see if that causes errors to appear in the log, which might give some info why the command is not running.

And of course, please share with us what you find. The community here is very helpful and knowledgeable and will be able to help you even further.

Thanks!
