[Bug 1071011] Re: specific device not available in client (passthrough) with high cpu load on host, none in client
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 dmidecode -s bios-version sudo dmidecode -s bios-release-date Thank you for your understanding. ** Tags added: bios-outdated-1604 needs-upstream-testing regression- potential ** Changed in: linux (Ubuntu) Status: Confirmed = Incomplete -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/1071011 Title: specific device not available in client (passthrough) with high cpu load on host, none in client To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1071011/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

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 (existing-arguments) or if you are using libvirt, you should be able to cd x86_64-softmmu sudo mv /usr/bin/kvm /usr/bin/kvm.orig sudo ln -s $(pwd)/qemu-system-x86_64 /usr/bin/kvm then test, then sudo rm /usr/bin/kvm sudo mv /usr/bin/kvm.orig /usr/bin/kvm -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/1071011 Title: specific device not available in client (passthrough) with high cpu load on host, none in client To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1071011/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

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 --enable-kvm -nam...) still a coredump message is shown, apport.log ends in wrote report /var/crash/_usr_bin_qemu-system-x86_64.0.crash -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/1071011 Title: specific device not available in client (passthrough) with high cpu load on host, none in client To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1071011/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

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 ** Changed in: qemu-kvm (Ubuntu) Status: Incomplete = New ** Also affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/1071011 Title: specific device not available in client (passthrough) with high cpu load on host, none in client To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1071011/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 1071011] Re: specific device not available in client (passthrough) with high cpu load on host, none in client
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 usable in the guest, while a reboot results in the sound card not being usable in the guest? ** Changed in: qemu-kvm (Ubuntu) Importance: Undecided = Medium ** Changed in: qemu-kvm (Ubuntu) Status: New = Incomplete ** Changed in: qemu-kvm (Ubuntu) Importance: Medium = Low -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/1071011 Title: specific device not available in client (passthrough) with high cpu load on host, none in client To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1071011/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 1071011] Re: specific device not available in client (passthrough) with high cpu load on host, none in client
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 tried a restart of the client first to keep the same kvm process. After that I've performed several poweroff's, including disconnecting from the mains for over a minute, but never seen the device working properly. An upstream install of qemu is okay if you have the proper apt commands (and sources.list alterations if needed) available.
