Hi Stefan, sorry for my very late response as I was temporarily out and unfortunately missed this email thread. For your question (remark), yes, you're right. This feature should not apply to specific <cpu mode='host-passthrough'... /> scenario. Something else to look into is that the feature can only work if the serving layer underneath by capabilities does support the request. Short, yes, this needs correction. - Wim10H.
