The VM has terminated unexpectedly during startup because of signal 6

Hi all,
I am trying to boot up my VM using vmcloak modify to make some manual changes. I'm getting the error below. This is a fresh vmcloak install on a fresh Ubuntu 16.04. Any ideas? Thanks.

Try running the VM without the --vm-visible option. You can then open VirtualBox manually, highlight the VM and click "show" (normally where start is in VBox) to get a GUI to interact with it.

The error you're getting there is from Virtualbox, not VMCloak, however VMCloak throws an exception as VirtualBox exits with an error code.
