Message-Id: <1258373983-8693-36-git-send-email-avi@redhat.com> Date: Mon, 16 Nov 2009 14:19:36 +0200 From: Avi Kivity <avi@...hat.com> To: linux-kernel@...r.kernel.org Cc: kvm@...r.kernel.org Subject: [PATCH 35/42] KVM: x86: disable paravirt mmu reporting From: Marcelo Tosatti <mtosatti@...hat.com> Disable paravirt MMU capability reporting, so that new (or rebooted) guests switch to native operation. Paravirt MMU is a burden to maintain and does not bring significant advantages compared to shadow anymore.
