From: Chuan-kai Lin <[EMAIL PROTECTED]> This patch is based on the one Anthony Liguori submitted to kvm-devel on July 2nd, which fixes PXE booting with KVM enabled but breaks PXE booting when not using KVM. I simplified Anthony's patch and duplicated the cpu_register_physical_memory call to ensure that the code retains its original behavior when kvm_allowed is 0.
