See docs/qdev-device-use.txt in the qemu(-kvm) source tarball. This will be quite a bit faster too (and it works since at least 0.12).

No, I for one haven't seen anything like you describe, and it'd definitely be useful to find and fix it. But I haven't used the old -net tap syntax for quite some time too - i started a test winXP guest now, let's see how it will work. /mjt -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
