Gerben, as per http://www.asus.com/Motherboards/SABERTOOTH_990FX/#support_Download_8 an update is available for your BIOS (1604). If you update to this, does it change anything? If not, could you please both specify what happened, and provide the output of the following terminal command: sudo

The way to check upstream qemu's git HEAD is: sudo apt-get build-dep qemu-kvm sudo apt-get install git git clone git://git.qemu.org/qemu.git cd qemu ./configure --target-list=x86_64-softmmu make then run it as cd x86_64-softmmu ./qemu-system-x86_64 --enable-kvm

Probably apparmor is blocking the executable. in /var/log/apport.log I can see the line: ERROR: apport (pid 4224) Fri Oct 26 22:29:35 2012: executable does not belong to a package, ignoring When copying qemu-system-x86_64 into /usr/bin and executing within that directory ( ./qemu-system-x86_64

Thanks, Gerben. If it were possible for you to run it by hand that would be easier. But to do it through libvirt without a package becomes more complicated. To undo your changes (in particular copying the qemu- system-x86_64 into /usr/bin), please do sudo apt-get install --reinstall qemu-kvm

Thanks for reporting this bug. Would it be possible for you to test this with the upstream qemu? Did this used to work consistently with older versions of qemu (say in precise)? Is there any pattern - for instance a full shutdown followed by power-on of the host results in the sound card being

Hi Serge, I cannot see any pattern on boot or reboot of the host. One cold boot (the first after not using the pci device for a long time) of the host resulted into the device working properly on the client, but then shutting down the client again reverted to problem described. I should have
