Open Stack

This may be due to misconfiguration in nova.conf on the compute node. You may have provided incorrect information how to contact Keystone. Double-check the [keystone_authtoken] section, in particular the URLs in there.
 
Also check the Nova compute log on the compute host for additional information.

Subject: [Openstack] Could not determine a suitable URL for the plugin

 

Hi

 

I've setup an openstack system based on the instructions here:

 

https://docs.openstack.org/newton/

 

I'm trying to launch an instance:

$ . demo-openrc 

$ openstack server create --flavor m1.nano --image cirros --nic net-id=da77f469-f594-42f6-ab18-8b907b3359e4 --security-group default --key-name mykey provider-instance

 

but get this error in the nova-conductor log file:

Any tips how to resolve this?
