Description of problem:
Fresh install of Fedora 17, added gnome-boxes to try it out.

I downloaded the Gnome 3.4 iso from the gnome site ( Gnomes in gnomes. Yeah, I know I'm silly;)

Started gnome-boxes from my account (Which is in the "administrators" group)

And got the following SELinux alert:

SELinux is preventing /usr/bin/qemu-kvm from write access on the file /home/spider/.libvirt/qemu/log/GNOME-3.4.iso.log.

*****  Plugin leaks (86.2 confidence) suggests  ******************************

If you want to ignore qemu-kvm trying to write access the GNOME-3.4.iso.log file, because you believe it should not need this access.
Then you should report this as a bug.  
You can generate a local policy module to dontaudit this access.
Do
# grep /usr/bin/qemu-kvm /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp

*****  Plugin catchall (14.7 confidence) suggests  ***************************

If you believe that qemu-kvm should be allowed write access on the GNOME-3.4.iso.log 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 qemu-kvm /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
