Description
Hey, I'm trying to get this to boot the first time. After following the README directions it just hangs about 30 seconds into starting up. The last log lines when it hangs are shown below. Any idea what the issue is?
I'm on Virtualbox 5.1.18 r114002 (Qt5.6.2) and MacOS 10.12.4 on an early 2015 Macbook Pro, and in Virtualbox I'm using 4GB RAM, 128MB video memory, 2 CPUs, and I've tried marking the ISO as Live CD/DVD

Research direction
Start with the README directions and the boot log ending at gIOScreenLockState, then review the reported VirtualBox 5.1.18 and macOS 10.12.4 configuration. Done means identifying a confirmed cause or documenting a reproducible workaround for this setup.
