From 2dc7094b5662c4446aa647b257d47a9412fbacc9 Mon Sep 17 00:00:00 2001 From: Matthew Gregan Date: Sun, 6 May 2007 10:59:46 +0300 Subject: [PATCH] KVM: Implement IA32_EBL_CR_POWERON msr Attempting to boot the default 'bsd' kernel of OpenBSD 4.1 i386 in a guest fails early in the kernel init inside p3_get_bus_clock while trying to read the IA32_EBL_CR_POWERON MSR. KVM logs an 'unhandled MSR' message and the guest kernel faults. This patch is sufficient to allow OpenBSD to boot, after which it seems to run fine. I'm not sure if this is the correct solution for dealing with this particular MSR, but it works for me.
