If you change the label to xen_image_t this should work fine. chcon -t xen_image_t para.img f16.img Can you run this from libvirt?
I've changed label and it works now. I used virt-manager for system installation.
Ok so this xen image is located in the /var/lib/libvirt/images by default in your case, right?
yes
Maybe we should just allow xend to manager virt_image_t.
I agree. Added to selinux-policy-3.11.1-52.fc18
