Are you not seeing this feature enabled? I was under the impression it got enabled if the number of CPUs are > 1. All of my VMs show it enabled and 2 CPUs listed in What are you experiencing? |

Without this setting, VirtualBox's UI will show a message "Invalid settings detected" if I/O APIC is not explicitly enabled. The guest (CentOS 7.0) will also show only one CPU. I am using VirtualBox version 5.1.14. |

Ok, let me update my VirtualBox; I assume you mean the CentOS 7.0 box in my Hashicorp list? |
|
I am using PuppetLab's CentOS base box: puppetlabs/centos-7.0-64-puppet |

Ah, that's why. They don't create them with that enabled when running via Packer. I make the assumption you're using my VMs for this project. I'll doublecheck there's no issues and merge this. |
