Checklist

[ ] Is your issue/contribution related with enabling some setting/option exposed by libvirt that the plugin does not yet support, or requires changing/extending the provider terraform schema?
- [ ] Make sure you explain why this option is important to you, why it should be important to everyone. Describe your use-case with detail and provide examples where possible.
- [ ] If it is a very special case, consider using the XSLT support in the provider to tweak the definition instead of opening an issue
- [ ] Maintainers do not have expertise in every libvirt setting, so please, describe the feature and how it is used. Link to the appropriate documentation
[ ] Is it a bug or something that does not work as expected? Please make sure you fill the version information below:

Description of Issue/Question

I am trying to implement a VM by following the documentation at:

https://kinvolk.io/docs/flatcar-container-linux/latest/installing/vms/libvirt/#terraform

terraform apply ...

Steps to Reproduce Issue

(Include debug logs if possible and relevant).

terraform init terraform apply

Additional information:

Do you have SELinux or Apparmor/Firewall enabled? Some special configuration?

karl@k8s:~$ tail -n 5 /etc/apparmor.d/abstractions/libvirt-qemu

Site-specific additions and overrides. See local/README for details.

include <local/abstractions/libvirt-qemu>

For ignition files

/var/lib/libvirt/flatcar-linux/ r, /var/tmp/mycluster-pool/ r,

Have you tried to reproduce the issue without them enabled? No
