In my view, the bottom line is: we need an _easy_ way of launching VMs when one doesn't want all the options of the managed approach. I back Avi on this one, I would like to be able to do qemu guest.img without worrying about configuration files, or XML, or parsing. That's not to say that a global configuration file for QEMU wouldn't be useful, but I think it would solve a different problem. When I read Avi's TODO, I basically thought about getting rid of the long command lines I had to store in scripts. I wanted to write that command line once, and then forgetting about it, until I needed to change it. I wanted an image to be self-contained as much as possible. That's what I set to achieve. All that said, I rethought Anthony's idea of storing plain text in the image and with proper tools, it can work out. I don't like the idea of having users overwriting and padding files, but the approach seems less of a hack than using empty snapshots. In short: I think we will need to have something like 'qemu-img cmdline' anyways, independent of the implementation. That's because I would like an implementation that does not depend on extra files. For that, we already have libvirt and the likes. Cheers, Jorge ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
