+
+other Packer debugging techniques are described in the Packer
+[documentation](https://developer.hashicorp.com/packer/docs/debugging).

+Add `-vvvv` flag to the Ansible's `extra_arguments` block in a Packer config

+Additionally, you can connect to Packer's VNC session using a VNC client.
+For TigerVNC you will need to enable the following settings:
+
+* Input -> View only (ignore mouse and keyboard)
+* Misc -> Shared (don't disconnect other viewers)
+
+By default Packer is running a VNC server on a random TCP port in the
+5900:6000 range. But for remote build environments it might be useful
+to use a specific port so that you can configure a firewall easily:
+
+```shell
+$ packer build ... -var vnc_bind_address=0.0.0.0 -var vnc_port_min=5900 \
