Bug Description
I'm running a virtual Windows SBS 2003 installation on a Xeon E3 Haswell system running Gentoo Linux. First, I used Qemu 1.5.3 (the latest stable version on Gentoo). I got a lot of machine check events ("mce: [Hardware Error]: Machine check events logged") in dmesg that always looked like (using mcelog):
Hardware event. This is not a software error.

I found this discussion on the vmware community: https:/
It seems that this is (at least partly) caused by the Qemu machine. I switched to Qemu 1.7.0, the first version to use "pc-i440fx-1.7". With this version, the errors almost disappeared, but from time to time, I still get machine check events. Anyways, they so not seem to affect neither the vm, nor the host.
The Haswell machine has been set up and running for several days without a single error message. They only appear when the VM is running. so I think this is actually some problem with the Haswell architecture (and not a real hardware error).

Still happens with qemu 2.0.0 and the same environment (Windows SBS 2003 32 bit guest on a Gentoo Linux amd64 Haswell host).
