From mboxrd@z Thu Jan 1 00:00:00 1970 From: Bandan Das Subject: [PATCH 1/4] nvmx: use warn_on for buggy cases when emulating invept/invvpid Date: Wed, 20 Jul 2016 18:25:33 -0400 Message-ID: <1469053536-11130-2-git-send-email-bsd@redhat.com> References: <1469053536-11130-1-git-send-email-bsd@redhat.com> Cc: pbonzini@redhat.com, rkrcmar@redhat.com, linux-kernel@vger.kernel.org To: kvm@vger.kernel.org Return-path: Received: from mx1.redhat.com ([209.132.183.28]:54318 "EHLO mx1.redhat.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1755328AbcGTWZ4 (ORCPT ); Wed, 20 Jul 2016 18:25:56 -0400 In-Reply-To: <1469053536-11130-1-git-send-email-bsd@redhat.com> Sender: kvm-owner@vger.kernel.org List-ID: If L1 hypervisor decides to try out something weird, alert the host but only less aggressively. Also, remove the comment regarding nested vpid support since it is no longer valid.
