It is probably a BIOS (therefore, kvm) bug. bochs bios used to not be able to checksum roms bigger than 64k. We probably lack the patch that fixes it. Please test the following rpm, and let me know about the results: http://brewweb.devel.redhat.com/brew/taskinfo?taskID=2167920 > Please test the following rpm, and let me know about the results:
