I can download and build a new ubuntu 18.04 image however once it finishes, qemu cannot boot the output qcow2 image, even if I remove all boot commands. I've tried numerous things, reinstalling grub and making sure the drive has the boot flag and it still doesn't boot. I just get the message "no bootable device" on kvm and also "no bootable device" running the output as a disk image with packer. The device identifier is /dev/vda and I am using an LVM drive on the entire volume with default setup settings. This template and all the boot commands worked perfectly fine in Ubuntu 16.04

Your template is wrong. Please ask on the mailing list.

jbsmith86 commented 5 years ago

Template works fine with raw, breaks in qcow2 seems to be a bug imo

jbsmith86 commented 5 years ago

This template is essentially what is on the qemu example https://www.packer.io/docs/builders/qemu.html

rickard-von-essen commented 5 years ago

Your template have a empty boot_command. Unfortunately the example in the docs is not functioning, we have already fixed that but the update hasn't been deployed yet.

@jbsmith86 I have somewhat of an identical issue and found that adding

"skip_compaction": "true",

to the "builders"-section of the JSON-file helped me out. Building a Debian Jessie amd64-box, not Ubuntu.

However the result is a significant bigger image! 1.1G for file debian-8.11.libvirt.box And unpacked, 3.8G: file box.img: QEMU QCOW Image (v3), 68719476736 bytes

Tested with my yet unpublished version of Packer - see #6955. Might be related to the handling of things in QEMU 3.0.0 too.
