Basic QEMU plugin questions


I am trying to test the qemu plugin but I am not sure what I need to prepare in the image to configure the VM’s network. For example, if I were starting with a basic Ubuntu cloud image and modifying that with Packer to install ssh, etc., what settings do I need to set for network?

I have an image running and the ssh port exposed (qemu is listening on the host port), but is seems the actual VM is not listening.
