Re: [Qemu-devel] Re: [kvm-devel] [PATCH][RFC] Allowing QEMU to directly execute a directory (and storing command line options in it)

I would like to think that having command line options separated by
spaces or newlines is a new configuration file format, but it's not.
This patch is not meant as a replacement for libvirt or any other
backend. It's just a replacement for shell scripts that serve the only
purpose of storing command line options. It should be a simple
solution for a simple problem. The complex solution for the complex
problem is already there and is called libvirt. I don't want to have
QEMU parse serialized XML just to replace my '-m 512 -soundhw es1370
-net nic,model=rtl8139' command line. I would simply like to store
that command line somewhere.

Anyways, it's obvious that this is a delicate issue for many people
here. I think the most non-disruptive way of doing this is the '-c'
command line option. It doesn't change QEMU default behaviour, it
doesn't add new hyphen-less options. I insist on the fact that this
should be a simple solution for a simple problem.
