ansible-role-kill_libvirt_vm

• check if the VM is running on the hypervisor
• destroy the VM (stops it)
• undefines it (optionally also --remove-all-storage)
• remove host cert from puppetmaster (optional)

Requirements

Libvirt

Cleaning Cert: puppet version >= 4

Role Variables

• hyper: the hypervisor where the inventory_hostname is running
• puppetmaster: the address to the puppetmaster, in case
  • kill_clean_puppet_cert: is True
• kill_libvirt_clean_storage: False
  • By default the role just undefines the VM which leaves any disk&storage associated with the VM
  • Setting this to True the role instead runs a "virsh undefine --remove-all-storage" command

Dependencies

TODO

• Can we setup a libvirt VM that spawns a VM or two and then we can try to destroy them? Paravirtualized or lxc or some other container perhaps?

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

    - hosts: servers
      roles:
         - { role: ansible-role-kill_libvirt_vm, when protected == "no" }

    - hosts: someotherservers
      roles:
         - { role: ansible-role-kill_libvirt_vm, when protected == "no" }

Then have group_vars that set "protected: no" for for example the development servers.

And then run ansible-playbook like this:

$ ansible-playbook site.yml -l develserver.example.org

Or if you want to do the same for a production server then (note the extra space at the beginning):

$ export HISTCONTROL="ignorespace"
$ HISTCONTROL="ignorespace"
$  ansible-playbook site.yml -l develserver.example.org -e protected=no
