But it seems that other kernel flavours don't have this. (See for example: <a href="http://lists.xen.org/archives/html/xen-devel/2012-09/txtV0mkHOtzj_.txt">http://lists.xen.org/archives/html/xen-devel/2012-09/txtV0mkHOtzj_.txt</a>) In older kernels it was not created automatically, but had to be mounted via xenfs. (See: <a href="http://old-list-archives.xenproject.org/xen-users/2009-07/msg00490.html">http://old-list-archives.xenproject.org/xen-users/2009-07/msg00490.html</a>). Not sure wheter some flavours still use this. So, I guess we cannot really rely on the fact that /proc/xen/capabilities is always present in dom0.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
