Great, and thanks for reporting back! > Btw, KVM wasn't needed until Bookworm. I can run autopkgtest-virt-qemu > on that without it. It however very much is needed since Trixie.

Apparently for some reason emulated boot takes longer in newer Debian releases. This may be due to a change in qemu. I did check the autopkgtest git history and could not spot a change that could have made boot take longer, or that shortened to boot timeout. But I think we can make things better on the autopkgtest side: https://salsa.debian.org/ci-team/autopkgtest/-/merge_requests/677 Let me know if you have comments. Cheers, Paride
