Title:
qemu Windows 7 BSOD when using hv-time
Status in QEMU:
Expired
Bug description:
When I use hv-time sub option and run CPU-Z or 3DMark (Physics Test)
the Windows 7 guest stops with BSOD (SYSTEM_SERVICE_EXCEPTION). It can
be easily reproduced by running CPU-Z. It will fail every second or
third time you execute CPU-Z and fail during "PCI detection". If I
disable hv-time I can run CPU-Z and 3DMark (Physics Test) without any
problems. QEMU was called with the following options:
/usr/bin/taskset -c 4,5,6,7 /usr/bin/qemu-system-x86_64 \
-machine q35,accel=kvm,kernel_irqchip=on \
-enable-kvm \
-serial none \
-parallel none \
-monitor none \
-vga std \
-boot order=dc \
-cpu host,hv-time \
-smp cores=4,threads=1,sockets=1 \
-m 8192 \
-k de \
-rtc base=localtime \
-drive
file=/srv/kvm/maggie-drive0.img,id=drive0,if=none,cache=none,aio=threads \
-mon chardev=monitor0 \
-chardev socket,id=monitor0,path=/tmp/maggie.monitor,nowait,server \
-netdev tap,id=net0,vhost=on,helper=/usr/lib/qemu/qemu-bridge-helper \
-device virtio-net-pci,netdev=net0,mac=00:00:00:02:01:01 \
-device virtio-blk-pci,drive=drive0,ioeventfd=on \
-device ioh3420,bus=pcie.0,id=pcie0,port=1,chassis=1,multifunction=on
I've removed the VFIO PCI passthrough line of my GPU to make
reproduction easier. In any case it happens in both scenarios so VGA
passthrough is not the root cause. It happens with linux-3.15-rc5 and
linux-3.14.3 with patch from commit mentioned at
https://bugzilla.kernel.org/show_bug.cgi?id=73721#c3
