After 1,5 days kvm hung up again (100% CPU, as above, same kernels, qemu-kvm
1.1.1+dfsg-1). This time I could get a backtrace using gdb that shows that
the bug is in the audio code/emulation.
So I'd like to be more precise about the audio configuration. The host has
a ASUS Xonar DX PCI-e audio card. As the host does not have an IOMMU, I'm
using an emulated ES1370 in the guest to capture host audio input. Due to
VNC, which I enabled trying to debug the guest crashes, I had to use
"vnc_allow_host_audio = 1" in /etc/libvirt/qemu.conf, otherwise libvirt would
set QEMU_AUDIO_DRV to none for some reason. AFAICT qemu-kvm is now using the
host's ALSA as the backend for the emulated sound card. The crashes happen with
VNC enabled or not.
lspci output for the host audio card:
03:04.0 Multimedia audio controller: C-Media Electronics Inc CMI8788 [Oxygen
HD Audio]
lsof output showing that qemu-kvm is probably using the ALSA backend (new kvm
process, I restarted it with the same configuration after the crash documented
in gdb output below):
kvm 27040 libvirt-qemu mem CHR 116,3 4507
/dev/snd/pcmC0D0p
Hope that helps finding the bug!
Cheers,
Mike
