Hey all,
Just started learning Packer today, so feel free to point me at docs I may have missed.
I think I’m running into this issue: Packer 1.8.0: QEMU fails to remove CD-ROM installation image during reboot (worked fine with 1.7.10) · Issue #66 · hashicorp/packer-plugin-qemu · GitHub Or, at least, something similar.
Am I reading that issue correctly in that newer versions of qemu wouldn’t have that problem?
Basically, when I try to build my Ubuntu 20.04 server image, the console eventually gets stuck at the language selection screen. Prior to that screen I spot a “failed to unmounting /cdrom” message.
A little while after that it boots directly to the language selection screen.
I have tried using older versions of Packer and older versions of the qemu plugin. I tried with, and without, use_pflash. When I tried using /usr/share/qemu/OVMF.fd, I just ended up in grub instead of subquitity. Which mad the boot_command fail.
Anyone have any other workarounds?
Debugging info:
System: PopOS 20.04
