There is a patch upstream that provides better error reporting if qemu fails to initialize SDL: http://git.savannah.gnu.org/cgit/qemu.git/commit/?id=3caf2562c21278aa9992bc7e6b5bbe98bc79f92e Using SDL with libvirt is tricky, so this patch will hopefully help users track down their issues, or at least file better bug reports.
