Ian, Sorry for asking an imprecise question. I understand the mechanism for turning on this flag. What was not clear to me was when we would turn this on. Regards, K.

What was not clear to me was when we would turn this on.Probably never. It was mainly intended as a proof of concept. There once was an idea that it might be possible run a Xen/linux kernel+a thin shim on bare metal with negligible loss of performance. With the paravirt ops approach being taken with the upstreaming work there is little point in that anymore.
