It could be an i387 emulation bug. I don't think so. Isn't it so that KVM and TCG are mutually exclusive choices? We see the problem if we pass --enable-kvm and don't see the problem if we don't pass that flag. From my limited understanding of qemu, not paying the flag means that the default TCG emulation is used. Am I wrong?
