Re: launching instance failed since of nova-network quantum

Hi ,

I preassume it is All in One Cloud Controller ( Nova, Glance, Keystone ) .
I have included some changes to nova.conf file . Can you try the below & restart all nova services .
Ensure all services UP & running before you launch instances .

Hi livemoon ,

by my experience, i think you can first try to update your python modules by the command " pip-python install -r tools/pip-requires ", then ensure your network service is ok by the command " nova-manage service list ". hope it can help you.



Best Regards.
