The <sysinfo> is fine at the top level, but the <smbios> element
should be kept within the <os> element, because that is the container
we have for all BIOS related config parameters, and whether you can
use <smbios> or not is conditional on  <os type='hvm'/> (ie you can't
use it with type=xen or type=exe).
