fix(ci): install cloud-image-utils in the publish lane (cidata seed ISO)#77
Merged
Conversation
Second publish run (28584050911) failed identically to the first even with images prefetched: the same 7 targets never reached SSH and their serial logs were 0 bytes — the guests never booted at all. Root cause: the RHEL-family/Amazon/Oracle/SUSE profiles deliver cloud-init via a cidata seed (needsCIDATASeed). bpfcompat prefers cloud-localds to build the seed ISO and silently falls back to a vvfat config drive when it's missing; those guests never boot from the vvfat fallback on the runner. The hosted runner doesn't ship cloud-localds (local dev boxes do, which is why all 11 profiles boot locally). The 7 failing targets are exactly the needsCIDATASeed distro list; the 4 Ubuntu/Debian targets use the NoCloud net seed and were fine. - apt-install cloud-image-utils (provides cloud-localds); - add qemu.log to the evidence artifact allowlist — its absence made this diagnosis harder than it needed to be.

Second publish run (28584050911) failed identically even with the prefetch fix — same 7 targets, but this time the evidence pinpointed it: their serial logs are 0 bytes. The guests never booted at all; downloads were never the (whole) problem.
Root cause
needsCIDATASeedroutes RHEL-family/Amazon/Oracle/SUSE profiles through a cidata seed ISO built withcloud-localds, silently falling back to a vvfat config drive when it's missing — and those guests never boot from the vvfat fallback on the hosted runner. The runner doesn't shipcloud-localds; dev boxes do (why all 11 profiles boot locally). The 7 failing targets are exactly theneedsCIDATASeeddistro list; the 4 Ubuntu/Debian targets use the NoCloud net seed and validated fine in both runs.Fix
apt-get install cloud-image-utils(providescloud-localds) with a comment explaining why.qemu.logto the evidence artifact allowlist — its absence made this diagnosis harder than it needed to be.Will re-dispatch after merge; third time with both fixes (prefetch + seed ISO) should be the real end-to-end proof.
