With kernel_irqchip=on it does not happen with qemu too, just like with qemu-kvm. So only 32bit userspace on 64bit kernel, and only with kernel_irqchip = OFF, and only with 32bit version of win7 or winXP. The kernel line is rather simple: $ ./x86_64-softmmu/qemu-system-x86_64 -enable-kvm -drive file=w7x32sp1.raw,if=virtio,snapshot=on -m 1G -net none -machine accel=kvm,kernel_irqchip=on Thanks! /mjt
