How reproducable is this? You make it sound like its easy to reproduce,
which would make me think kvm does something iffy.
Please, share a bit more information with us, start by telling us the
reproducability, your machine info, your kernel config (userspace
version number of kvm?)

Indeed, it should not. In this case it looks like corrupt page tables
that are responsible, you have a lot of badness preceding the Eeek.
