Created attachment 411859 [details] qemu callstack during 100% spin As the title suggests, once the client finishes the scroll test, the guest hangs, and qemu-kvm spins at 100% CPU. Host: Fedora 12/x86_64. Guest: Fedora 13/i686 (2GB, 2CPUs). Hardware: 2 x Xeon L5530, 12GB, 9800GTX/512MB, nVidia proprietary driver. The machine has a serial console (via telnet), but I did not see any type of OOps/crash message. It looks like a host problem. qemu version: $ rpm -qa | grep qemu qemu-common-0.12.3-4.fc12.x86_64 qemu-system-mips-0.12.3-4.fc12.x86_64 qemu-launcher-1.7.4-7.fc12.noarch qemu-img-0.12.3-4.fc12.x86_64 qemu-system-m68k-0.12.3-4.fc12.x86_64 qemu-kvm-0.12.3-4.fc12.x86_64 qemu-system-ppc-0.12.3-4.fc12.x86_64 qemu-system-sh4-0.12.3-4.fc12.x86_64 qemu-system-sparc-0.12.3-4.fc12.x86_64 qemu-system-cris-0.12.3-4.fc12.x86_64 qemu-system-arm-0.12.3-4.fc12.x86_64 qemu-system-x86-0.12.3-4.fc12.x86_64 gpxe-roms-qemu-0.9.9-1.20091018git.fc12.noarch qemu-user-0.12.3-4.fc12.x86_64 qemu-0.12.3-4.fc12.x86_64 Guest command line: qemu-kvm -cdrom /dev/sr0 -serial telnet::9006,server,nowait -soundhw es1370 -net nic,vlan=1,macaddr=00:E0:81:B0:FB:06,model=e1000 -net tap,vlan=1,ifname=tap60 -net nic,vlan=2,macaddr=00:E0:81:B0:FB:16,model=e1000 -net tap,vlan=2,ifname=tap61-m2048 -name Fedora-i386-F13 -hda /usr/drives/kvm/Fedora-i386/Fedora-i386-F13.img -smp2 -usb -usbdevice tablet -vga vmware -vnc :6 -boot c qemu strace and pstack (during gtkperf attached) - Gilboa

This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
