commit f17274f4c9670bb403a450ca1c8b7006897a9872 Author: Avi Kivity <avi> Date: Mon May 11 14:21:10 2009 +0300 KVM: SVM: Remove port 80 passthrough KVM optimizes guest port 80 accesses by passthing them through to the host. Some AMD machines die on port 80 writes, allowing the guest to hard-lock the host. Remove the port passthrough to avoid the problem.
