[Qemu-devel] Documentation about qemu config file

[Valerio Pachera]

Hi, I'm interested about the option -writeconfig/-readconfig.
I'm looking for some documentation about the format of the file, the
syntax of all possible options and if there's a library that helps to
read and write this file from external applications.

I've been writing a sort of a cli to manage guests across different
servers and I wish to manage guest settings by qemu config file.

Thank you in advance.

(/me checks the timestamp -- no, you didn't send this on April 1st.
Okay. It is not a joke then, and the QEMU community is supposed to be
open and welcoming. Therefore:)

Have you heard of libvirt <http://libvirt.org/>?

-readconfig and -writeconfig are documented badly.  They use an INI file
format[*].

Unfortunately, it covers only a subset of the command line options.

The (flawed!) QMP command query-command-line-options currently shows
exactly the covered ones.

I second Laszlo's recommendation to check out existing solutions such as
libvirt before rolling your own.
