Moreover, some devices - like disks have the <seclabel/> too. And I was wondering whether you don't have those elements in the XML. The other reason for me asking domain XML is so that I could try to reproduce locally on my system. > > I did together with Michael Tremer some debugging and Michael > posted our > results in the bugtracker.

Ah, reading the bz transcript, you are not passing the path directly into the XML rather than use a volume from a storage pool. This is supported but the previous case is more tested. Again, this would help me to narrow down the possible causes. > > Maybe the describtion in the bug report hepls to go furhter, when > not > say what you need (logs) to debug the problem. Maybe I'm misreading this, but I think I've told you what I need to debug the problem. Moreover, it's usually better to provide as many information as possible when debugging a problem. Even a tiny little thing that user think of as trivial may look crucial in eyes of experienced developer with insight in the project.

Anyway, I'd like to continue the discussion in the BZ.
