Description Martin 2013-07-03 12:09:23 UTC
Description of problem:
Gnome Boxes installation from image on read-only NFS storage.
SELinux is preventing /usr/bin/qemu-system-x86_64 from 'open' accesses on the file /mnt/globalsync/fedora/fedora-alt/stage/19-RC3/Fedora/x86_64/iso/Fedora-19-x86_64-netinst.iso.

*****  Plugin catchall_boolean (89.3 confidence) suggests  *******************

If you want to allow confined virtual guests to manage nfs files
Then you must tell SELinux about this by enabling the 'virt_use_nfs' boolean.
You can read 'virt_selinux' man page for more details.
Do
setsebool -P virt_use_nfs 1

*****  Plugin catchall (11.6 confidence) suggests  ***************************

If you believe that qemu-system-x86_64 should be allowed open access on the Fedora-19-x86_64-netinst.iso 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-system-x86 /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
