[Kernel-packages] [Bug 1307473] Re: guest hang due to missing clock interrupt
I believe I have the same problem, place a guest under any amount of load, let's say 'yum upgrade' and the network stack goes out to lunch for 1-5 seconds.

I need to amend comment #39, moving from 3.13.0-30 to 3.13.0-27 did not eliminate the problem. It would seem that it takes a couple of hours following a reboot for the symptoms to manifest with 3.13.0-27. -- 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/1307473 Title: guest hang due to missing clock interrupt Status in QEMU: New Status in “linux” package in Ubuntu: Confirmed Status in “qemu” package in Ubuntu: Confirmed Bug description: I noticed on 2 different systems that after upgrade from precise to latest trusty VMs are crashing: - in case of Windows VMs I'm getting BSOD with error message: "A clock interrupt was not received on a secondary processor within the allocated time interval." - On linux VMs I'm noticing "hrtimer: interrupt took 2992229 ns" messages - On some proprietary virtual appliances I'm noticing crashes an due to missing timer interrupts QEMU version is: QEMU emulator version 1.7.91 (Debian 2.0.0~rc1+dfsg-0ubuntu3) Full command line: qemu-system-x86_64 -enable-kvm -name win7eval -S -machine pc- i440fx-1.7,accel=kvm,usb=off -cpu host -m 4096 -realtime mlock=off -smp 4,sockets=1,cores=4,threads=1 -uuid 05e5089a- 4aa1-6bb2-ef06-ab4d020a -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/win7eval.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=localtime -no-shutdown -boot strict=on -device piix3-usb- uhci,id=usb,bus=pci.0,addr=0x1.0x2 -drive file=/var/vm/win7eval.qcow2,if=none,id=drive-virtio-disk0,format=qcow2 -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x4,drive=drive-virtio- disk0,id=virtio-disk0,bootindex=1 -drive file=/home/damarion/iso/7600.16385.090713-1255_x86fre_enterprise_en- us_EVAL_Eval_Enterprise-GRMCENEVAL_EN_DVD.iso,if=none,id=drive- ide0-0-0,readonly=on,format=raw -device ide-cd,bus=ide.0,unit=0,drive =drive-ide0-0-0,id=ide0-0-0 -drive file=/home/damarion/iso/virtio- win-0.1-74.iso,if=none,id=drive-ide0-1-0,readonly=on,format=raw -device ide-cd,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -netdev tap,fd=24,id=hostnet0 -device e1000,netdev=hostnet0,id=net0,mac=52:54:00:38:31:0a,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa- serial,chardev=charserial0,id=serial0 -device usb-tablet,id=input0 -vnc 127.0.0.1:1 -device VGA,id=video0,bus=pci.0,addr=0x2 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1307473/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
