Hi all, What is the easiest way to stop a DOS session in QEMU? I want to have an AUTOEXEC.BAT that does something and then quits, in DOS on a QEMU disk image, so that I can just call it from Linux with no drama. There are various hits in google but I did not find anything that seemed very simple

Maybe it's a language problem. "sharing disk" and "network file system" are the same thing here. Trying to physically connect the same disk to two computers sounds idiotic. Is there some way to emulate "network file system" access from two (or more) separate QEMU instances to the same disk image?
