:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that qemu-kvm should be allowed open access on the bootcd.iso <Inconnu> 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 qemu-kvm /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2012-03-05 08:55:39 UTC
You will need to turn on the virt_use_samba boolean

$ setsebool -P virt_use_samba 1

Comment 2 Sylvain Petreolle 2012-03-07 12:55:17 UTC
Thanks for the feedback.
Why is this disabled by default ?
I didn't find an answer in the available documentation.

Comment 3 Daniel Walsh 2012-03-07 19:09:10 UTC
Because it allows a virtual machine to read any data on your system that is being shared via samba.  Most people to not share their hosts samba data with their virtual machines.
