=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 Thanks for your reply, the audio= patch works.
I can play audio between DomUs.

=E6=96=BC 2010/9/20 =E4=B8=8B=E5=8D=88 09:20, Felix Kuperjans =E6=8F=90= =E5=88=B0: 
 I can only answer your third question:

You can switch to using ALSA with qemu (no idea why this is *not* the
default), e.g. by recompiling xen-tools with the attached patch. In KVM,
a QEMU_AUDIO_DRV=3D"alsa" environment variable works, too. No idea whethe=
r
XEN accepts it or not.

Another way with further control would be to use PulseAudio in the Dom0
and in the DomUs (I think there is even a windows port), which is able
to send the audio data over network connections, so you won't need any
virtual sound cards. I have no setup/tutorial at hand, but it should be
easy to find on the internet.

Regards,
Felix

 Dear all:

      I am trying to send a fake event to input layer of QEMU,
i.e. keyboard and mouse.

      QEMU provides two API to send these input event,
that is, kbd_put_keycode() and kbd_mouse_event() for keyboard and
mouse, respectively.
And these functions will make a suitable packet for low-level
hardware, e.g. PS/2 or USB.

      For a PS/2 mouse, there is a call chain  ps2_mouse_event() =3D>
ps2_mouse_send_packet() =3D> ps2_queue()
when the function kbd_mouse_event() is called.
However, when I make a fake PS/2 mouse packet and directly call
ps2_queue()
to put the packet to PS/2 queue.
I store the PS2MouseState "s" when 8042 initializes and call
ps2_queue() to send a event,
for example,
          ps2_queue(&s->common, 0x1001);
          ps2_queue(&s->common, 0);
          ps2_queue(&s->common, 0);

And I also insert some debug  message in ps2_read_data() function,
it works well and reads data from queue correctly..
But the mouse pointer does not move (even right/left click).
I also set the default mouse to "Mouse $0: QEMU PS/2 Mouse" in QEMU
consloe,
but the result is the same. What else I forgot to signal? How could I
fix it?


       The second question is when I create a PV Linux (Ubuntu),
the mouse pointer does not move correctly.
The screen (VNC) shows a black point and a mouse pointer,
and their speed does not the same.
In HVM XP, we can use usbdevice=3D'tablet' to fix it,
but the same line does not work in PV Linux. How could I fix it?


      The last question is that does the sound can be shared (mixed)
between multiple DomainUs?
(The device will be busy when I create a domain.) If can, how could I do?


     Thanks!

Best Regards,
Tang-Hsun Tu
