:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that systemd-logind (deleted) should be allowed setattr access on the sr0 <Unbekannt> 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 systemd-logind /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Daniel Walsh 2012-02-20 14:20:37 EST
This looks like this might be a crash between libvirt handling of /dev/sr0 and systemd.
Comment 2 Daniel Walsh 2012-02-20 14:21:29 EST
Dan Berrange, shouldn't libvirt relabel /dev/sr0 to removable_device_t when it is done with it?
Comment 3 Lennart Poettering 2012-03-15 15:57:25 EDT
as CD drives are marked for "uaccess" systemd-logind will give the currently logged in user on the seat access to it via ACL and as soon as the session is swicthed will update the ACL.
