Public bug reported:
autopkgtest-virt-qemu sometimes hangs when running tests on noble
images. Originally reported by schopin, who also provided a reproducer:
pull-lp-source -d hello
autopkgtest-buildvm-ubuntu-cloud -r noble
autopkgtest -U hello*.dsc -- qemu ./autopkgtest-noble-amd64.img
I've been able to reproduce it with debugging enabled:
autopkgtest -ddd -U hello_2.10-3.dsc -- qemu --debug --show-boot
/path/to/image
It can get stuck during different stages, but AFAICT always during
"copydown" operations, log excerpts follow. It may be a coincidence, but
this started happening around the time linux-image-6.8.0-11-generic
(6.8.0-11.11) migrated to noble. The testbeds I used booted 6.6 but then
rebooted into that 6.8 kernel after being upgraded by autopkgtest.
