First of all, your reply is really fast.Thank you very much.
My understanding of your answer is, this is an Ansible bug, when perform the installation of the cloudlet gateway.
I see from https://github.com/cmusatyalab/elijah-openstack#cloudlet-gateway that the installation of the cloudlet gateway is optionally.
Q1:
I perform the script probably three or four times, still trapped in this step, i think your solution
is that behind this error steps (temporary skip this error) directly according to
https://github.com/cmusatyalab/elijah-openstack/tree/master/cloudlet-gateway to constrain it
to that role by using '- tags gateway', am i right?
Can i skip this error,and do the next step ?
Q2:
In addition,I also don't understand what you have said roles is to point to what, I will see some related information to learn further.
Q3:
Step 8. Create a pool of floating IP addresses
These can be assigned to VMs to allow public access to them.
$ nova floating-ip-bulk-create <cidr>
Is the floating IP addresses defined by myself, so the cidr can be like this:10.0.1.XX,same as the network segment of flat_iface?
Please forgive me if I say something unclearly.
