Thanks for the information. I guess it would be nice to document this=20 somewhere (except in code)... At least I could not find any information abo= ut=20 it beside some patch (Not directed at you, Roland). Any idea where? Besides, it has one Problem: It is not backwards compatible. Using it on=20 earlier Xen Versions yields the normal tls versions (xen 3.1). Isnt the=20 userbase of existing xen installations bigger than the one of some point in= =20 =46C5 test releases? Ugh. Leaning a bit far out of the door with that one considering my knowled= ge=20 about it... Sorry about that.
