[Qemu-devel] Intel HDA issue with TCG x86_64

[Peter Crosthwaite]

Hi All,

Im running:

qemu-system-x86_64 -drive file=./qemu-pc/debian,if=scsi,bus=0 -m 2048
-soundhw hda

Drive is Aureliens debian squeeze desktop image:

http://people.debian.org/~aurel32/qemu/amd64/

QEMU configured as:

../qemu/configure --target-list=x86_64-softmmu --enable-kvm
--audio-drv-list="alsa oss"

I get a single warning of this:
main-loop: WARNING: I/O thread spun for 1000 iterations

At the time the guest starts sounding on the sound card, then the
guest becomes very slow (much slower than even normal TCG).

It works just fine on KVM:

qemu-system-x86_64 -drive file=./qemu-pc/debian,if=scsi,bus=0 -m 2048
-soundhw hda -enable-kvm

I'm on Ubuntu 10.04.

Regards,
Peter
