Package: vmdb2
Version: 0.40-2
Severity: normal

Hi,

I think the situation is similar to what happened during the bookworm 
release in bug #1031364, but now with the option orphan_file. Today I 
noticed that on ci.d.n the tests that use qemu fail when running tests 
on oldstable (buster) because the image (which is built with 
autopkgtest-build-qemu which uses vmdb2 under the hood) doesn't boot. 
When I run the test manually with the --show-boot option enabled in 
autopkgtest's qemu backend, the test ends like below. The test hangs for 
1 minute after """/dev/vda1 has unsupported feature(s): FEATURE_C12"""

This seems to have started to happen after we upgraded the host from 
bookworm to trixie.

I suspect that the code here needs to be expanded: 
https://sources.debian.org/src/vmdb2/0.40-2/vmdb/plugins/mkfs_plugin.py/#L63

I'll also note that it seems that code should depend on the target suite 
and should only be conditionally applied.

Paul
