From d17051cb8d223dffd6bb847b0565ef1654f8e0e1 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Thu, 29 Jul 2010 14:47:57 +0200 Subject: KVM: PPC: Generic KVM PV guest support We have all the hypervisor pieces in place now, but the guest parts are still missing. This patch implements basic awareness of KVM when running Linux as guest. It doesn't do anything with it yet though.
