I've been trying to figure out how to get an ONIE-bootable VM running. It's hard to exhaustively list all the things I've tried, but most recently I compiled the ISO from source using the Docker build here. When I booted that up in VMWare with either IDE or SCSI hard drives that got me:
It hangs after that. I also tried installing from these instructions and the result was effectively the same. I got a different error, but the boot process never makes it to the part where it actually looks for the ONIE installer.
Has anyone else gotten this to work? If so, what did you do?
