From 345dcaa8fde7fa70252d58c862bf41fd2149ca2c Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Wed, 12 Aug 2009 15:29:37 +0300 Subject: [PATCH] KVM: VMX: Adjust rflags if in real mode emulation We set rflags.vm86 when virtualizing real mode to do through vm8086 mode; so we need to take it out again when reading rflags.
