Description Gaetan Cambier 2010-01-23 12:08:18 UTC 
Résumé:

SELinux is preventing /usr/sbin/xenstored "read write" access on privcmd.

Description détaillée:

SELinux denied access requested by xenstored. It is not expected that this
access is required by xenstored and this access may signal an intrusion attempt.
It is also possible that the specific version or configuration of the
application is causing it to require additional access.

Autoriser l'accès:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug
report.
