Souhrn:

SELinux is preventing qemu-kvm "write" access on /var/lib/libvirt/qemu.

Podrobný popis:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by qemu-kvm. It is not expected that this access
is required by qemu-kvm 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://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug
report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.

audit2allow suggests:

#============= svirt_t ==============
allow svirt_t virt_var_lib_t:dir { write add_name };
allow svirt_t virt_var_lib_t:sock_file create;
