Hi Rickard: Please let me know if anymore info is required. Just to summarize the whole thing again, I have a qemu disk image with the username and password that is in my packer json file. I also created a toy provisioner script that just should create a directory However, no matter how many things I try, the packer never detects the VM has booted up. I use headless=false and can easily see that VM has booted up. I can even login at the qemu windows, but packer literally never detects it and just sticks there. And eventually times out even with large timeouts. I want to use packer rather than libguestfs, etc.
Can you please help on this?
