Description

Can't reproduce this here - what's going on in the guest when you can't kill it? Maybe an strace would shed some light what's going on? This is universally true, kill or clicking on Close Window fails to kill qemu-kvm anywhere during bootup or runtime. (In reply to comment #2) > This is universally true, Well, it's universally untrue here. I've tried everything I can think of to reproduce it, but it works fine here. Does it work okay if you just do e.g. 'qem-kvm -drive file=boot.iso,media=cdrom' ? I removed "-soundhw all" and this problem went away. This wasn't a problem on F-10. Thanks, that helped a lot I took a good look at this and it appears to be some sort of exit-time lockup in qemu's SDL audio driver. Looks like SDL_AudioQuit() is waiting for a thread that never quits Doesn't happen with -nographic, -vnc or QEMU_AUDIO_DRV=alsa A couple of things make me not care much about this: 1) We recommend people use VNC rather than SDL 2) If you use libvirt in F11, sound will be disable anyway There's now a pulseaudio driver in qemu too, so I'm thinking we should build with --audio-drv-list=pa,sdl,alsa,oss I've tested this out and it fixes this particular problem. Haven't actually tested sound, yet though :-) Okay, I've built the following into dist-f12: http://koji.fedoraproject.org/koji/buildinfo?buildID=98887 * Tue Apr 21 2009 Mark McLoughlin <markmc> - 2:0.10-13 - Enable pulseaudio driver to fix qemu lockup at shutdown (#495964) Warren: could you give this a whirl and see if it helps? It'd also be good if you could check that sound still works for you. If it looks good, I'll build for F-11 too. Thanks OK, [root@homedesk QEMU]# rpm -qa | grep qemu qemu-system-x86-0.10-13.fc12.i586 qemu-img-0.10-13.fc12.i586 qemu-common-0.10-13.fc12.i586 My testings: # Sound is very good export QEMU_AUDIO_DRV=pa #Sound is problem enought often, but guest is stable export QEMU_AUDIO_DRV=alsa # guest OS is problem, qemu need to `kill -9` export QEMU_AUDIO_DRV=sdl # Sound is problem, but guest is like stable export QEMU_AUDIO_DRV=oss Command line to run guest: qemu-kvm -localtime $VGA -hda centos-5.img -boot c -net nic,macaddr=52:54:00:12:34:C5 -net tap -soundhw ac97 -m 1024 Guest is CentOS-5.3 No improvement here with the -13.fc12 build. It fails to be killable long before it runs the kernel. (In reply to comment #8) > No improvement here with the -13.fc12 build. Could you run with '-monitor stdio' and confirm that the monitor is no longer responding after you click the window's close button? Also, run under gdb and after you click close, hit Ctrl-C and do "thread apply all bt full" This helpful? (running qemu-kvm on WinXP guest. Here is how I run:
qemu-kvm -localtime -vga std -m 512 -usbdevice tablet -name "Windows XP" -hda ~/VirtualMachines/raw.img -k en-us -soundhw es1370

qemu-*-0.10-15.fc11.i586 is configured without 'pa' support (--audio-drv-list=sdl,alsa,oss). It is problem for me, because on my system qemu by 'alsa' audio-drv works bad and freeze virtual machine by 'sdl' audio-drv. export QEMU_AUDIO_DRV=alsa export QEMU_AUDIO_DAC_FIXED_FREQ=48000 export QEMU_AUDIO_ADC_FIXED_FREQ=48000 export QEMU_ALSA_DAC_BUFFER_SIZE=4096 made quality of sound applicable... (In reply to comment #14) > export QEMU_AUDIO_DRV=alsa > export QEMU_AUDIO_DAC_FIXED_FREQ=48000 > export QEMU_AUDIO_ADC_FIXED_FREQ=48000 > export QEMU_ALSA_DAC_BUFFER_SIZE=4096 > > made quality of sound applicable... Probably off-topic for this BZ, but this does not work reliably for me running qemu-kvm on a WinXP guest: QEMU_AUDIO_DRV=alsa QEMU_AUDIO_DAC_FIXED_FREQ=48000 QEMU_AUDIO_ADC_FIXED_FREQ=48000 QEMU_ALSA_DAC_BUFFER_SIZE=4096 qemu-kvm -localtime -vga std -m 512 -usbdevice tablet -name "Windows XP" -hda ~/VirtualMachines/raw.img -k en-us -soundhw es1370 I haven't figured out what makes it work (or not) yet. Tested on latest package from koji: -10.16. When it doesn't work, I get static/choppy/low-quality sound from the guest, the same as if I didn't have the extra FREQ/SIZE exports. Guys - please try and keep bug reports confined to a single issue This bug is just about the lockup at shutdown using the SDL audio driver. Tom: thanks much for the stack traces. Could you test this f12 version from Koji to see if using the pulseaudio backend resolves the issue for you? It worked for me http://koji.fedoraproject.org/koji/buildinfo?buildID=99512 if it does lockup using this version, please get a stack trace like the one above. Nope, still "hangs on shutdown" for me. (I'm missing some recent debuginfo packages. Let me know if you need me to update all of those and rerun.)

Ahh, I may have misread your comment. I think you wanted me to rerun testing the "pa" backend, not the SDL one. Right? The above is another test using the SDL backend. I reran specifying "QEMU_AUDIO_DRV=pa qemu-kvm ....", and had NO problems with sound or with shutdown.

Many thanks Tom, that's exactly what I wanted. Okay, I think that confirms that using the pulseaudio backend fixes this bug. Could you confirm one last thing for me? If you run qemu-kvm without any QEMU_AUDIO_DRV variable set, is it automatically using the pa backend? It did in my testing, but I just want to be sure. If it does, then I think we should switch to pulseaudio for F11 final. It should also resolve the issues reported by Sergei in bug #496627 *** Bug 499059 has been marked as a duplicate of this bug. *** (In reply to comment #19) > (In reply to comment #18) > > > I reran specifying "QEMU_AUDIO_DRV=pa qemu-kvm ....", and had NO problems with > > sound or with shutdown. > > Many thanks Tom, that's exactly what I wanted. > > Okay, I think that confirms that using the pulseaudio backend fixes this bug. > > Could you confirm one last thing for me?

And it hangs on shutdown: (gdb) where #0 0x0000003f02e07b2d in pthread_join (threadid=139964373285136, thread_return=0x0) at pthread_join.c:89 #1 0x0000003f1481166e in SDL_WaitThread (thread=0x7f4bf8039c30, status=0x0) at src/thread/SDL_thread.c:270 #2 0x0000003f14808dfa in SDL_AudioQuit () at src/audio/SDL_audio.c:629 #3 0x0000003f148082cd in SDL_QuitSubSystem (flags=65535) at src/SDL.c:196 #4 0x0000003f1480834e in SDL_Quit () at src/SDL.c:222 #5 0x0000003f02236c82 in __run_exit_handlers (status=<value optimized out>, status=<value optimized out>, listp=<value optimized out>, run_list_atexit=<value optimized out>) at exit.c:78 #6 *__GI_exit (status=<value optimized out>, status=<value optimized out>, listp=<value optimized out>, run_list_atexit=<value optimized out>) at exit.c:100 #7 0x0000003f0221e9e4 in __libc_start_main (main=<value optimized out>, argc=<value optimized out>, ubp_av=<value optimized out>, init=<value optimized out>, fini=<value optimized out>, rtld_fini=<value optimized out>, stack_end=0x7fff2a428678) at libc-start.c:252 #8 0x00000000004076d9 in _start () Current language: auto; currently minimal (gdb) If I run with "QEMU_AUDIO_DRV=pa qemu-kvm -localtime -vga std -m 512 -usbdevice tablet -name "Windows XP" -hda ~/VirtualMachines/raw.img -k en-us -soundhw es1370" [tbl@tlondon ~]$ QEMU_AUDIO_DRV=pa qemu-kvm -localtime -vga std -m 512 -usbdevice tablet -name "Windows XP" -hda ~/VirtualMachines/raw.img -k en-us -soundhw es1370 [tbl@tlondon ~]$ I get a (sort of) working microphone, and no hang on shutdown. Also, I noticed that when I run without QEMU_AUDIO_DRV=pa, pavucontrol reports only an output stream for qemu, while when I run with QEMU_AUDIO_DRV=pa I get both input and output streams. Conclusion: default is SDL. Ah, I've just discovered 'qemu-kvm -audio-help' ... hidden command line switch! And also, just discovered this: audio/paaudio.c:510: INIT_FIELD (can_be_default = ) 0, i.e. it will not use the pulseaudio backend by default, you need to explicitly request it. We could patch it, but it does suggest that upstream doesn't think this backend is up to snuff yet ... even though it works far better for us than other backends. Hmm. I did stumble across one issue..... I (foolheartedly) tried installing/running skype on the WinXP guest with pulseaudio enabled..... Ended up putting qemu-kvm into a bad state. I'll open a separate BZ on this if I can reproduce.... Regarding the default use of pulseaudio, do you suppose this could be handled with an "environment setting" of "QEMU_AUDIO_DRV=pa" in a /etc/profile.d/qemu-kvm.sh or some such.... Well, if setting pulseaudio as the default is the "right thing", the following seems to "work for me": [root@tlondon ~]# cat /etc/profile.d/qemu-kvm.sh # Make pulseaudio be the default audio backend export QEMU_AUDIO_DRV=pa [root@tlondon ~]# After creating that file, and then logging out and back in again, running qemu-kvm without an explicit "QEMU_AUDIO_DRV" selects pulseaudio. Would probably need a .csh version too.... Big picture wise, we just want an audio backend that integrates well with our desktop. We use pulseaudio as a sound server, so I think it makes sense to use the pulseaudio backend. The SDL library is just an indirection layer which, in theory, an app like qemu can use to integrate with the desktop while using the same API in all cases. Except it's broken. Long term, we'll want to re-direct audio over e.g. VNC/QXL if the user is connecting to the VM remotely - i.e. we'll want a "output the display and audio to the local desktop console" (similar to -sdl) and a "output the display and audio to a remote client" (similar to -vnc currently) But right now, if we can conclude that the pulseaudio backend is better than the SDL backend, I think we should just switch to it by default. The only thing stopping us from doing that right now is figuring out why upstream doesn't think the pulseaudio backend is suitable as the default. >> The only thing stopping us from doing that right now

Unfortunatelly, not all so good with 'pa' as we want. From time to time I have guest OS slowdown and qemu-kvm eat 100% of CPU till guest OS shutdown. So, 'pa' interface show best sound quality result, but it is less stable as alsa.

I've pushed qemu-0.10.4-2.fc11 with the pulseaudio driver enabled; it still isn't used by default, though qemu-0.10.4-2.fc11 "works for me" with "QEMU_AUDIO_DRV=pa" set....
