Register steal time within KVM. Everytime we sample the steal time information, we update a local variable that tells what was the last time read. We then account the difference.

Will leaving the old value around confuse the steal time calculation? -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
