![]() ![]() The Vagrantfile I used is in my Network Automation Workshop GitHub repository. Cisco IOS and Nexus OS were running in a VIRL VM, Ansible and Junos vSRX were running in Vagrant-controlled VMs. In the Ansible for Networking Engineers webinar I demonstrated scripts that work on Cisco IOS, Nexus OS and Junos. Each virtual machine thus has a fixed IP address reachable from other virtual machines (like an out-of-band management network). ![]() When you’re using VMware Fusion or Workstation as your virtualization environment Vagrant uses vmnet interface to connect to the individual virtual machines. If you want to run Ansible on the host on which you run Vagrant, you need this one. Use the information in this article only when running Ansible in a virtual machine. Accessing network devices outside of the host machine is easy (Vagrant VMs have full access to outside networks), accessing other virtual machines (network devices) running on the same host could become an interesting exercise, more so if you use VirtualBox. However, Ansible running in a virtual machine has to be able to access other network devices via SSH or HTTP(S) connections. If you’re running Windows you have no options anyway – Ansible doesn’t run on Windows.Recovering the virtual machine took just a few minutes. Doing that on my workstation would be a disaster. I managed to completely mess up my Python environment while trying to work with multiple Ansible versions simultaneously.While Mac OSX is almost Unix, but there might be slight discrepancies between Linux and OSX behavior that would result in hard-to-troubleshoot failures.I prefer running Ansible in another virtual machine for these reasons: ![]() Most network automation tutorials using Ansible with Vagrant assume that you’re running Ansible on your host machine.
