Summary:

SELinux is preventing libvirtd "write" access on libvirt.

Detailed Description:

[libvirtd has a permissive type (virtd_t). This access was not denied.]

SELinux denied access requested by libvirtd. It is not expected that this access
is required by libvirtd 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.

Allowing Access:

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 (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.
