Juerg Haefliger, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.13-rc3 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/973536 Title: kvm brings Oneiric host to a grinding halt Status in “linux” package in Ubuntu: Incomplete Status in “qemu-kvm” package in Ubuntu: Confirmed Bug description: I'm running a Windows7 guest in KVM via libvirt/virt-manager on a Oneiric desktop 64-bit. Every once in a while (2-3 times a week, sometimes daily) the CPU usage goes berserk and the host becomes very unresponsive and unusable. This also happened once with a Breezy guest so it's not strictly a Windows issue. I'm just seeing it more often with Windows because that's what I run daily. More information attached, let me know what other info I should collect, the next time the machine is in that state. --- ApportVersion: 1.23-0ubuntu4 Architecture: amd64 DistroRelease: Ubuntu 11.10 InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release amd64 (20111012) KvmCmdLine: UID PID PPID C SZ RSS PSR STIME TTY TIME CMD 116 2892 1 13 327807 1062024 0 07:34 ? 00:49:31 /usr/bin/kvm -S -M pc-0.14 -enable-kvm -m 1024 -smp 1,sockets=1,cores=1,threads=1 -name Windows7 -uuid 63a736b8-2d14-4354-8974-83c3f0d71ea1 -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/Windows7.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=readline -rtc base=localtime -boot c -drive file=/home/juergh/VirtualMachines/Windows7.img,if=none,id=drive-virtio-disk0,boot=on,format=raw,cache=none,aio=native -device virtio-blk-pci,bus=pci.0,addr=0x6,drive=drive-virtio-disk0,id=virtio-disk0 -netdev tap,fd=19,id=hostnet0 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:56:6f:49,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -usb -vnc 127.0.0.1:0 -vga std -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 MachineType: Hewlett-Packard HP EliteBook 8530w NonfreeKernelModules: nvidia Package: qemu-kvm 0.14.1+noroms-0ubuntu6.2 PackageArchitecture: amd64 PccardctlIdent: Socket 0: product info: "RICOH", "Bay8Controller", "", "" manfid: 0x0000, 0x0000 function: 254 (unknown) PccardctlStatus: Socket 0: 3.3V 16-bit PC Card Subdevice 0 (function 0) bound to driver "pata_pcmcia" ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.0.0-17-generic root=UUID=076a3371-4882-4e13-a456-9855c6fb4caf ro ProcVersionSignature: Ubuntu 3.0.0-17.30-generic 3.0.22 Tags: oneiric running-unity Uname: Linux 3.0.0-17-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm admin cdrom dialout libvirtd lpadmin mock plugdev sambashare dmi.bios.date: 12/08/2009 dmi.bios.vendor: Hewlett-Packard dmi.bios.version: 68PDV Ver.
