Footnotes: 1. Using colons for lists works only as long as the list elements don't contain colons. Fine for numbers. No good for filenames, network addresses, ... 2. QemuOpts helped us reduce the number of ad hoc option parsers, improving consistency and error messages quite a bit. Having every user of colon lists roll their own ad hoc parser slides back into the hole that motivated QemuOpts. Let's try to avoid that, please. 3. The existing QemuOpts syntax for list-valued options (repeating the option) doesn't have either of these problems. -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
