SELinux is preventing vboxadd-service "read write" access on /dev/vboxadd.

Detailed Description:

[vboxadd-service has a permissive type (initrc_t). This access was not denied.]

SELinux denied access requested by vboxadd-service. It is not expected that this
access is required by vboxadd-service 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.

Looks like we need a polcy for vboxadd-service

Comment 2 Miroslav Grepl 2009-09-10 12:00:27 UTC
What is your VirtualBox release ?

Comment 3 Jason 2009-09-10 12:42:32 UTC
VirtualBox 3.04 - believe it was the latest version up until yesterday.

It appears to be working properly now. No selinux errors that I see. Thank you!

Closing as NOTABUG as the issue seems to be fixed, but no cause was identified in this bug.
