Bug 550704

Résumé:

SELinux is preventing /usr/bin/qemu-system-x86_64 "write" access on sr0.

Description détaillée:

SELinux denied access requested by qemu-system-x86. It is not expected that this
access is required by qemu-system-x86 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.
