Here's the Fedora bug:

https://bugzilla.redhat.com/show_bug.cgi?id=599091

Note that I've already pushed a patch upstream that fixes the problem 
(reduces save time for a 512MB guest from 3:47 to 0:56), and eric Blake 
has posted a more refined patch that wastes less space by invoking dd 
twice (once for libvirt's header, and again for the image) - that hasn't 
been pushed yet, but will almost definitely supercede my patch before 
the libvirt-0.8.2 release.
