From eb6f302edff9da963e687bf6c15dcf88843b1c3b Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Tue, 25 Nov 2008 20:17:09 +0100 Subject: KVM: SVM: Allow read access to MSR_VM_VR KVM tries to read the VM_CR MSR to find out if SVM was disabled by the BIOS. So implement read support for this MSR to make nested SVM running.
