Try to execute # chcon -t bin_t /usr/share/virtualbox/VBoxCreateUSBNode.sh does it work then?
Yes. No alerts since then. I have up-to-date F16 (updates-testing) and VirtualBox-4.1-4.1.0_73009_fedora15-1.i686.
Miroslav I think we should just add files_exec_usr_files(udev_t) Fixed in selinux-policy-3.10.0-19.fc16 Need to back port this fix to RHEL6.
