This patch provides support for the -filefd command line option. This option will allow passing of a filename and its corresponding file descriptor to QEMU at exec time.

I take it that if filename contains ',', then we have to escape it on the command line? Is it worth passing fd first and file second by default, as a possible way to avoid the need for escaping, or does the option parser not care about ordering?
That's a good question. The options can be ordered either way so I don't think we'll force fd to be specified first. I imagine this should behave no differently than "-drive file=xyz,if=none,...". I ran a quick test using -drive with a filename that had a comma, and (escaped or not) it failed on the option parsing. So it looks like if you have a path with a comma you're not going to have any luck. -- Regards, Corey
