Why does a KVM guest show continuous hard drive access of KVM host ?

Solution Verified - Updated -

Issue

  • I am running RHEL6.3 as KVM host.
  • I have a single KVM guest running.
  • I notice that when my guest is running the PC hard drive is access almost continuously, like a heart beat pulse.
  • Why is this? This activity will more than likely kill my hard drive?

Environment

  • Red Hat Enterprise Linux 6.3 as KVM host.
  • Windows XP as guest.
