From a68a6a7282373bedba8a2ed751b6384edb983a64 Mon Sep 17 00:00:00 2001 From: Marcelo Tosatti Date: Thu, 1 Oct 2009 19:28:39 -0300 Subject: [PATCH] KVM: x86: disable paravirt mmu reporting 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.
