:SELinux is preventing /usr/bin/qemu-kvm from 'getattr' accesses on the file /usr/share/alsa/alsa.conf.
:*****  Plugin catchall (100. confidence) suggests  ***************************
:If you believe that qemu-kvm should be allowed getattr access on the alsa.conf file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep qemu-kvm /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Daniel Walsh 2012-09-17 12:09:52 EDT
Is this a virtual machine setup to play sound using pulseaudio?
Comment 2 Nicolas Chauvet (kwizart) 2012-09-17 14:36:32 EDT
Yes(In reply to comment #1)
> Is this a virtual machine setup to play sound using pulseaudio?
Yes, but only because it's a virtualized desktop.
Comment 3 Daniel Walsh 2012-09-17 19:04:41 EDT
Ok We should probably allow this.
