From ff651cb613b4cc8aa2e4284525948872b4d77d66 Mon Sep 17 00:00:00 2001 From: Wincy Van Date: Thu, 11 Dec 2014 08:52:58 +0300 Subject: KVM: nVMX: Add nested msr load/restore algorithm Several hypervisors need MSR auto load/restore feature. We read MSRs from VM-entry MSR load area which specified by L1, and load them via kvm_set_msr in the nested entry. When nested exit occurs, we get MSRs via kvm_get_msr, writing them to L1`s MSR store area. After this, we read MSRs from VM-exit MSR load area, and load them via kvm_set_msr.
