OpenStack: List State of All VMs

Hi All! Today’s post is a quick script to show how you can get all your OpenStack VMs and their state in a single command. Check it out!

For the impatient: Use this link os-vm-state-sh and rename to .sh

What’s Going On?

The nova list command returns just a subset of information we want; you have to use it in conjunction with the nova show command to get all the output you want. In my case I wanted a single command to show me the VM information by host, tenant, and state (such as RUNNING). The script gives you a good starting point for your own needs and is very simple.

Here’s the output:

vm_id|vm_host|vm_tenant|vm_name|vm_state

Run the output through sort, load it into a spreadsheet, or use the output as input for another script.

Happy Computing! 🙂
