Date: Wed, 26 Aug 2009 13:29:28 +0300 From: Avi Kivity <avi@...hat.com> To: kvm@...r.kernel.org Cc: linux-kernel@...r.kernel.org Subject: [PATCH 06/47] KVM: ignore reads to perfctr msrs From: Amit Shah <amit.shah@...hat.com> We ignore writes to the perfctr msrs. Ignore reads as well. Kaspersky antivirus crashes Windows guests if it can't read these MSRs.
