Comment 6 for bug 1307225

I got a new Haswell based system a few days ago. It has been running fine without warnings but today I started a VirtualBox VM and got a MCE soon afterwards. "MCA: Internal parity error" like everyone else. From reading this bug and the vmware link in the first post it seems like this problem occurs on all virtualization solutions using hardware acceleration on Haswell based systems. It happens on Qemu, Virtualbox and Vmware and it happens on both Linux and Windows.

Do anyone have connections within Intel and can pull some strings to have them look at this? It looks like the MCE is always non fatal but perhaps there are other unknown side effects. A microcode update might solve it.
