Description of problem:
This occurred while running qemu-kvm.
The VM was hosting the F18 installer in another VM with /dev/sdb configured as the install target.
SELinux is preventing /usr/sbin/smartd from 'read' accesses on the blk_file sdb.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that smartd should be allowed read access on the sdb blk_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep smartd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
