Packer: VirtualBox build fails with NS_ERROR_FAILURE

[znerd]

When running a very simple Packer script for a VirtualBox VM on a CentOS 7.3 system without X11, then VBoxManage fails with an error saying:

VBoxManage error: VBoxManage: error: The virtual machine 'packer-virtualbox-ovf-1495287397' has terminated unexpectedly during startup because of signal 6
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component MachineWrap, interface IMachine

Some Googling seems to indicate it may be related to the lack of X11…

My system:

• Packer 1.0.0
• CentOS 7.3/x86_64
• VirtualBox 5.1.22

Set headless to true.

I changed that, but it's not resolving the issue. Here's the output:

Question: is Packer supposed to support running in a headless environment?

Oops. Never mind. The error changed.
