I'm getting a lot of these in kernel 3.11.0-rc1:

Jul 19 19:53:06 ps kernel: kvm: zapping shadow pages for mmio generation
wraparound
Jul 19 22:37:47 ps kernel: kvm: zapping shadow pages for mmio generation
wraparound
Jul 20 00:07:24 ps kernel: kvm: zapping shadow pages for mmio generation
wraparound
Jul 20 00:11:04 ps kernel: kvm: zapping shadow pages for mmio generation
wraparound
Jul 20 00:39:14 ps kernel: kvm: zapping shadow pages for mmio generation
wraparound
Jul 21 00:25:32 ps kernel: kvm: zapping shadow pages for mmio generation
wraparound

There seems to be one line in the kernel log for every reboot of a WinXP
guest, and I'm getting a bit bored with it. I don't understand what
those messages mean? What can I do to stop them flooding the log?
