:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that python should be allowed search access on the images <Unknown> 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 xend /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2012-02-16 10:03:14 UTC
It looks like you have xen images located in /var/lib/libvirt/images?

Comment 2 Daniel Walsh 2012-02-16 15:51:05 UTC
I don't see why we would block this.

> It looks like you have xen images located in /var/lib/libvirt/images?

Yes, I had a xen image file there.  I had the same problem with xen images stored on other ext3/ext4 disk partitions mounted via fstab.  The python script works with SELinux disabled.

Comment 4 Miroslav Grepl 2012-03-15 17:10:17 UTC
It has been added to f16.
