Triaging old bug tickets... can you still reproduce this issue with the latest version of QEMU and OpenBSD? Or could we close this ticket nowadays?

I can reproduce it with the following systems/versions: - Debian 6: QEMU PC emulator version 0.12.5 (qemu-kvm-0.12.5) - Fedora 20: qemu-system-x86-1.6.1 (from Fedora repository) qemu-1.7.0 (latest release version) qemu-1.7.50 (latest development snapshot, "git cloned" today, 20140212) all of the above hosts are running x86_64 linux. The first OpenBSD version that I ran as a VM, v5.1, experienced the problem. All subsequent versions experience the problem. The above tests were performed using OpenBSD v5.4 (amd64). I will open an OpenBSD bug report for this problem as well, and update this report with the OpenBSD bug ID. There's an interesting RedHat bug report concerning this problem: URL: https://bugzilla.redhat.com/show_bug.cgi?id=508801#c34 Here an excerpt: -snip- Gleb Natapov 2009-12-23 10:37:44 EST I posted patch to provide correct PCI irq routing info in mptable to kvm mailing list. It works for all devices except for SCI interrupt. BIOS programs SCI interrupt to be 9 as spec requires, but OpenBSD thinks that it is smarter and moves it to interrupts 10. Qemu will still send it on vector 9 and OpenBSD will enter the same infinity recursion. This can be triggered by issuing system_powerdown on qemu monitor. -snip- Michael Tokarev reported this problem on the kvm mailing list in 2011: URL: http://www.spinics.net/lists/kvm/msg51311.html I compiled qemu as follows: -snip- cd qemu-src-dir mkdir -p bin/native cd bin/native ../../configure \ --prefix=/usr/local/qemu-dev-snapshot-20140212 \ --target-list=x86_64-softmmu \ --enable-kvm \ --enable-spice \ --with-gtkabi="3.0" \ --audio-drv-list=pa,sdl,alsa,oss \ --extra-cflags='-I/usr/include/SDL' -snip- I'm running OpenBSD with the following command: -snip- #!/bin/bash DEF=/usr/bin/qemu-system-x86_64 QEMU_LATEST=/usr/local/qemu-1.7.0/bin/qemu-system-x86_64 QEMU_DEV=/usr/local/qemu-dev-snapshot-20140212/bin/qemu-system-x86_64 $QEMU_DEV \ -machine accel=kvm \ -name obsdtest-v54 \ -S \ -machine pc-i440fx-1.6,accel=kvm,usb=off \ -boot c \ -m 2048 \ -realtime mlock=off \ -smp 2,sockets=2,cores=1,threads=1 \ -uuid 8b685793-2510-473e-b97e-822a4cf2fbca \ -no-user-config \ -monitor stdio \ -rtc base=utc,driftfix=slew \ -global kvm-pit.lost_tick_policy=discard \ -no-hpet \ -drive file=/guest_images/obsdtest_v54.raw,if=none,id=drive-virtio-disk0,format=raw,cache=none \ -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 \ -drive 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 \ -chardev pty,id=charserial0 \ -device isa-serial,chardev=charserial0,id=serial0 \ -k en-us \ -device cirrus-vga,id=video0,bus=pci.0,addr=0x3 \ -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 \ -net nic \ -net user -snip- The OpenBSD disk image I used for testing is 143MB compressed, 10G uncompressed.
