If libvirt uses virtlogd instead of passing the file path directly to QEMU we shouldn't relabel the chardev source file, otherwise virtlogd will get a permission denied while reloading. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=143098
You missed a digit and I'm too lazy to check 10 bugs for a reproducer ;)

I see you are changing the parser code, but you are not changing the Relax-NG schema, neither any test.

I'm guessing you want to keep this away from users, right? You should not be parsing it from the XML then. Or you should add a thing there that the XML supports. Not just a random attribute. Either keep this data in private structure or even better, just add the same thing as you would do with: <seclabel relabel="no"/> with all the details of course. The user can see it, can supply it, old releases support it, all the stuff is there already. I'm open to suggestions, but NACK to random "wannabe private" attributes.
