I don't really like this approach. I don't want to have a totally separate management interface just for Xend to use (via xenstore).

Can't Xend use the monitor like every other management tool?

If the monitor really isn't sufficient, then I'd suggest allowing an
open file descriptor to be specified on the -vnc arg, eg

  -vnc localhost:3,passwdfd=6

In general, I strongly dislike passing file descriptors like this.

And then let QEMU read the password from this file descriptor. I'd rather
XenD just used the monitor though - it'll ultimately need to use it anyway
to perform disk/network hotplug amongst other things.

If there are reasons that Xend doesn't want to interact with the monitor (for instance, if you want to support monitor redirection), we can certainly discuss how to enhance the monitor (like having multiple monitor instances). Ultimately, we need to have everyone use the same interface to interact with QEMU.
