<div>We absolutely want to use upstream Bifrost and not duplicate a bunch of work already done. That said, I don't recall any discussion or agreement about sticking to running it in a VM. If we choose that path in the short term, it would be my hope that
long term there was a viable path to full containerization of Bifrost in a systematic baby steps iterative approach.</div>
