From d910f5c1064d7ff09c31b0191564f9f99e210f91 Mon Sep 17 00:00:00 2001 From: Glauber Costa Date: Mon, 11 Jul 2011 15:28:19 -0400 Subject: KVM guest: KVM Steal time registration This patch implements the kvm bits of the steal time infrastructure. The most important part of it, is the steal time clock. It is an continuous clock that shows the accumulated amount of steal time since vcpu creation. It is supposed to survive cpu offlining/onlining.
