Description of problem:
SELinux is preventing /usr/bin/rm from 'unlink' accesses on the lnk_file vboxguest-4.2.51.

*****  Plugin catchall_labels (83.8 confidence) suggests  ********************

If you want to allow rm to have unlink access on the vboxguest-4.2.51 lnk_file
Then you need to change the label on vboxguest-4.2.51
Do
# semanage fcontext -a -t FILE_TYPE 'vboxguest-4.2.51'
where FILE_TYPE is one of the following: NetworkManager_tmp_t, NetworkManager_unit_file_t, abrt_tmp_t, abrt_unit_file_t, abrt_var_cache_t, accountsd_unit_file_t, admin_crontab_tmp_t, alsa_tmp_t,

Then execute: 
restorecon -v 'vboxguest-4.2.51'


*****  Plugin catchall (17.1 confidence) suggests  ***************************

If you believe that rm should be allowed unlink access on the vboxguest-4.2.51 lnk_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 rm /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
