Notably (and for Libvirt only): - '-object' takes a detour through JSON, and uses sometimes =on/=off or sometimes =yes/=no. - '-accel' is not used at all - '-machine' does not use short-form boolean options by sheer luck. The only known usage in Libvirt, for instance, is for "-chardev" and "-vnc". Paolo
