You DON'T want to rely on qemu detecting the format itself. That is a CVE waiting to happen. If you hand a raw disk to the guest, and the guest writes particular metadata to resemble some other format, and then qemu probes that other format, you have allowed the guest to take over the host. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
