I'm seeing these MCE messages too.

My hardware is i7 4790K on a Gigabyte Z97X Gaming GT motherboard.

I run a mixture of Linux and Windows (client and server editions)
guests. Hipervisor is kvm. I'm seeing these MCE messages since I
virtualized a Windows Server 2008 R2 SP1. Neither Windows XP nor Windows
8.1 guests showed any messages.

For a few minutes I was worried my hardware was faulty, but this bug
reports somewhat gives me hope the hardware is OK.

Pasted below is my /var/log/mcelog

Title:
  Running a virtual machine on a Haswell system produces machine check
  events

Status in QEMU:
  New

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://communities.vmware.com/thread/452344

  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).
