Subject: Re: [PATCH] KVM: SVM: Update destination when updating pi irte

This seems to be a different issue. Joao's patch tries to fix the issue
that IRTE is not changed. The problem I encountered is that IRTE does
get changed, thus the destination field is also cleared by
amd_iommu_activate_guest_mode().
