The only way to do this with libvirt 0.8.1 is to write a wrapper script
which adds arguments and invokes the real qemu, then point libvirt to
the location of the wrapper instead of the real qemu. Not the most
trivial task.
Does this way breaks libvirt? libvirt also uses the qemu-monitor
If I change the arguments for monitor, I think it will break libvirt.
what I want to do is sending some commands to qemu-monitor,
I don't want to change existed things.

That's different than the 0.8.1 of your subject line. Yes, 0.8.3 makes
it easier to add additional arbitrary arguments to the qemu command line
via your XML file. The list archives has several examples of this; most
recently:

Another question, how can I use the remote protocol(arbitrary qemu monitor commands)?
Thanks, Lai.
