How does this one look? It should address your concern about duplicating data in both vcpu and vmcb. I have tested it with both 32bit and 64bit Windows successfully. -Wei =================Fix 32bit guest VM save/restore issues associated with SYSENTER MSRs on AMD platforms. This patch turn-on SYSENTER MSRs interception for 32bit guest VMs on AMD CPUs. With it, hvm_svm.guest_sysenter_xx fields always contain the canonical version of SYSENTER MSRs and are used in guest save/restore. The data fields in VMCB save area are updated as necessary.
