without stdout/stderr of "virt-builder: error: dnf -y --best upgrade: command exited with an error" it's not possible to see what's really going on. I put the virt-builder traces in the attachment. How can I output more information? Thanks Eric (In reply to Eric Auger from comment #2) > I put the virt-builder traces in the attachment. How can I output more > information? Thanks Eric this is question to virt-builder developers. I was going to say a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1280029 However you're seeing this bug in RHEL 7.3 with 1.32.7, where the bug *should* be fixed. If you look at the logs, you'll see: No '/dev/log' or 'logger' included for syslog logging cat: /lib/firmware/amd-ucode/: Is a directory No '/dev/log' or 'logger' included for syslog logging Disabling early microcode, because kernel does not support it. CONFIG_MICROCODE_[AMD|INTEL]!=y 1810 blocks and then dnf doesn't do any "Verify" lines. This probably indicates that one of the %post scripts is bailing out, causing dnf to (quite correctly) return an error. The error is picked up by virt-builder because it indicates that the dnf update command failed. This is probably caused because of the very different kernels in RHEL 7.3 (hence the appliance environment) and Fedora 23. You can replace the --update option with the equivalent dnf command, ignoring the error code, something like: virt-builder --run-command 'dnf -y update ||:' This is probably not something that we can fix in libguestfs. It's a side effect of trying to modify a much newer guest using a much older host kernel, and generally we recommend that you always try to use a same/newer host when modifying guests, *or* you explore the --firstboot options. OK, thank you Richard for your feedbacks. Shall we close the bug then? Thanks Eric |
Created attachment 1191869 [details] virt-builder traces Description of problem: When launching the following command on ARM aarch64 (mustang): virt-builder fedora-23 -o ./f23 --arch aarch64 --root-password password:123456 --hostname f23guest --update dnf -y --best upgrade is called and it looks it returns an error that prevents virt-builder from succeeding. As a consequence virt-builder fails creating the guest image: virt-builder: error: dnf -y --best upgrade: command exited with an error When launching the same command without --update and doing the "dnf -y --best upgrade" on the guest, the guest gets properly updated (although the same warning exists: Disabling early microcode, because kernel does not support it. CONFIG_MICROCODE_[AMD|INTEL]!=y). So the user experience is different. The same command with fedora-24 works fine. Version-Release number of selected component (if applicable): virt-builder libguestfs-tools: Version : 1.32.7 Release : 1.el7 How reproducible: 100% Steps to Reproduce: 1. launch virt-builder fedora-23 -o ./f23 --arch aarch64 --root-password password:123456 --hostname f23guest --update -v -x Actual results: see attachement below. Expected results: Guest image is created and properly updated Additional info:
