BTW, as I tried to touch exactly the same place yesterday (trying to convert it to QemuOpts) -- what does this "node" mean? For example, with -device [type=]devicetype,foo=bar,xzy=abc this creates a new device for each "invocation" of option. But what does this `-numa node' mean? Can there be anything else besides node? Why it is needed/used for? This -numa option is the last one which uses the old option parsing mechanism (there's also some smbios-related thing but it's simple to convert, I almost got it ready yesterday), but it is rather non-standard. Thanks, /mjt
