Incorrect booted image after creating Qemu image

[junland]

Overview of the Issue

This may or may not be related to issue #66, packer fails to boot into created VM image however boots into the downloaded ISO.
I've tried plugin versions 1.0.0 and the latest 1.0.9, however both give the same outcome.

Reproduction Steps

1. Add answers.cfg to the http directory.
2. Land the packer config with the 1.0.0 plugin as alpine-100.pkr.hcl
3. Land the packer config with the 1.0.9 plugin as alpine-109.pkr.hcl
4. Initialize both configs:
   a. packer init alpine-100.pkr.hcl
   b. packer init alpine-109.pkr.hcl
5. Run the 1.0.0 plugin config.

   PACKER_LOG=1 packer build alpine-100.pkr.hcl
   

6. Observe output and Qemu display.
7. Run the 1.0.9 plugin config.

   PACKER_LOG=1 packer build alpine-109.pkr.hcl
   

8. Observe output and Qemu display.

You will notice in both instances after the VM runs through the boot_steps process and reboots, that it goes back into the ISO without booting into the created image. I'm able to the confirm that both created VM disks (In this case, the qcow2 images) are able to boot just fine. It seems after the reboot, packer / packer-plugin-qemu is not able to drop the ISO file after it reboots.
