Package: qemu-kvm
Version: 0.12.4+dfsg-1
Severity: important
Yesterday i installed Ubuntu10.4 on qemu-kvm from Lenny backports. Now i start
it with this options:
kvm /var/mmn/vm/Ubuntu10.4/Ubuntu.img -name "Ubuntu 10.4" -M pc -cpu phenom -m
1G -rtc base=utc -vga vmware -k de -soundhw ac97 -usb -usbdevice tablet -boot c
I also tried all other ALSA sound devices available in qemu-kvm. And always i
got this message on console:
alsa: Unexpected state 1
But this message comes in a loop and slows down the vm. Sound is not available.
I found a path that fixes the loop and sound works fine. But 100% CPU load so
this patch is only a stopgap:
