vsphere-iso: Failure to Power-On VM after reattach_cdroms removes excess CD/DVD drives #516
Description
Overview of the Issue
Multiple CD-ROM drives are mounted in our packer build, and then we use reattach_cdroms=1 to remove the excess CD-ROMs at the end of the build.
The packer build completes successfully, but if we try to power on the VM created by Packer, we get an error message:
Module DevicePowerOn power on failed. Failed to start the virtual machine.
The IDE device (disks/CD-ROM) configuration is incorrect.
There is an IDE slave with no master at ide0:1. This configuration does not work correctly in virtual machines. Move the disk/CD-ROM from ide0:1 to ide0:0 using the configuration editor.
We only experience this issue after upgrading to version 1.2.5 (or later) of the plugin.
Reproduction Steps
Configure the vsphere-iso build as per the simplified buildfile provided below. Ensure multiple CD/DVD drives are mounted by using the "cd_files" and "iso_urls" options. Ensure the excess drives are removed by specifying "reattach_cdroms=1". Make sure the plugin is at least version 1.2.5.
Power-On the VM after the packer build is complete, and you will see the error.
The same error can be reproduced by creating a new VM manually in vCenter with two CD/DVD drives both attached to "IDE 0". If the first CD/DVD drive is then subsequently removed leaving only "CD/DVD drive 2", the VM does not power on and the same error message is displayed.
