There was a change in 9front some time before the release of the amd64 ISOs that seems to have caused it. I was able to boot the 386 ISO (9front-7408.1d345066125a.386.iso) and a amd64 kernel built from the source contained within that ISO. There was about a full year of development between that ISO and when I started seeing the issue, so it's not a very useful data point :P. cinap on #cat-v had some pointers for troubleshooting: 2020-05-29 07:19:47 cinap_lenrek so go to /sys/src/boot/pc 2020-05-29 07:19:55 cinap_lenrek in the mkfile, theres a test.iso target or something 2020-05-29 07:20:02 cinap_lenrek you can adjust that 2020-05-29 07:20:07 qbit ok 2020-05-29 07:20:24 cinap_lenrek basically, you want a workflow where you just run a command to generate a new iso with the kernel 2020-05-29 07:20:28 cinap_lenrek nothing else 2020-05-29 07:20:35 cinap_lenrek thats good enougth to troubleshoot this 2020-05-29 07:20:41 cinap_lenrek and then boot it from vmd Sorry it isn't much help!
