I don't like this because it turns command-line options into ABI. Also, it puts there some options for which -writeconfig is actually able to produce a QemuOpts equivalent, such as -monitor. I have a few patches here that convert almost every option that matters into QemuOpts so that -writeconfig records it: -m, -bios, -localtime, -S, -M, -smp, -numa, -nodefaults, -no-shutdown, -no-reboot. The only thing that is left basically is -display, where I chickened out. > Finally, this series exposes a new -query-capabilities option which dumps the > QemuOpts schema's via JSON to standard output (along with some other goodies > like the version info and supported QMP commands). > > The purpose of this series is to change the way management tools (esp libvirt) > interact with QEMU to determine capabilities.

However, we can definitely apply 1/2/7/8/9 now. Paolo
