Description Matěj Cepl 2010-06-30 08:39:32 EDT

SELinux is preventing /sbin/ebtables "search" access .

Podrobný popis:

[ebtables je v toleratním režimu (virtd_t). Přístup byl povolen.]

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

Povolení přístupu:

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

Virt folks,
