[Xen-users] no sound emulation support in qemu-dm in xen-3.3

[Alexander Piavka <piavka@xxxxxxxxxxxx>]

 Hi,

I've installed xen3.3 on gentoo linux and created HVM domain with
soundhw='sb16'
But the HVM domain fails to start with error:
------------------------------------------------
#  cat /var/log/xen/qemu-dm-winXP.log
domid: 3
qemu: the number of cpus is 1
Unknown sound card name `sb16'
Valid sound card names (comma separated):

-soundhw all will enable all of the above
------------------------------------------------

 If i change to soundhw='es1370' it also fails to start with apropriate 
message. Only then i set to soundhw='all' HVM starts ok, but it, of course 
, does not detect any sound devices.
It looks like qemu-dm does not have emulation support for any sound devices:
--------------------------------------------
# /usr/lib64/xen/bin/qemu-dm -soundhw ?
Valid sound card names (comma separated):

-soundhw all will enable all of the above
--------------------------------------------

 In xen3.1 and xen3.2 it worked ok, also i'm using exactly same gentoo 
system configuration and similar kernel config as for xen3.1 and xen3.2.
 So I unpacked xen-tools 3.3 sources and compiled qemu manually
I tweaked with  tools/ioemu-qemu-xen/xen-setup configure sound options to 
no avail. As i allways got:
---------------------------------------------
xen-3.3.0 # ./tools/ioemu-qemu-xen/i386-dm/qemu-dm -soundhw ?
Valid sound card names (comma separated):

-soundhw all will enable all of the above
----------------------------------------------

 Then I took xen-tools 3.2.1 sources and compiled qemu manually
and it got compiled with sound drivers out of the box:
-----------------------------------------------
xen-3.2.1 # ./ioemu/i386-dm/qemu-dm -soundhw ?
Valid sound card names (comma separated):
sb16        Creative Sound Blaster 16
es1370      ENSONIQ AudioPCI ES1370

-soundhw all will enable all of the above
-----------------------------------------------

 Anyone has an idea what is wrong with qemu in xen3.3 and how to fix it?

 Can i safely use qemu-dm from xen-3.2.1 with xen-3.3 ?

 Thanks
 Alex
