This environment represents multiple VMs. The VMs are all listed
above with their current state. For more information about a specific
VM, run `vagrant status NAME`.

Went through this issue as well. If you’re like me, you just need to pull down the latest code for this chapter.

If you’re following an old version of the book, or the youtube playlist you’ll want to update your Vagrantfile and inventory file (hosts.ini) to the latest published in this repo.

vagrant destroy your old machines and vagrant up the new ones, then

ansible multi -i hosts.ini -a "hostname"

and you should get the output you’re expecting

Was able to make it work, after reading this answer https://stackoverflow.com/a/35969858 It seems that I did not have an ansible.cfg file and this was creating this error.

wget https://raw.githubusercontent.com/ansible/ansible/devel/examples/ansible.cfg
~/three_servers  pwd
/Users/florin/three_servers
~/three_servers  ls
Vagrantfile  ansible.cfg

 ~/three_servers  ansible -m ping multi

I tried ansible.cfg but still same error
