I went down that road but you need to check the to-be-switched-into tss, which isn't available directly from vcpu so we would have to either pass the tss as a parameter to the function or at least a flag indicating that we're going into vm8086 mode.
There are other callers of kvm_load_segment_descriptor that would need updating and it already takes a few extra parameters. That's why I went down this road.
Happy to change though if you'd prefer a different approach. -- Regards, Anthony Liguori -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
