If it does indeed work on the Redhat packages then that seems<br>to indicate that there is something that doesn't work when libvirt is<br>built on non-redhat systems which may be related.</blockquote><div><br></div><div>I can reply this question, :) <br></div><div>I didn't delete the comment, and you're unable delete your comment in bugzilla.<br></div><div>I just set it to Private as I mention some downstream info, so,..
