From 809c79137a192d7e881a517f803ebbf96305f066 Mon Sep 17 00:00:00 2001 From: Maxim Levitsky Date: Tue, 4 May 2021 17:39:36 +0300 Subject: [PATCH] KVM: nSVM: remove a warning about vmcb01 VM exit reason While in most cases, when returning to use the VMCB01, the exit reason stored in it will be SVM_EXIT_VMRUN, on first VM exit after a nested migration this field can contain anything since the VM entry did happen before the migration. Remove this warning to avoid the false positive.
