For example Xen 4.2.1 on my system does not work with xenified OpenSuse 12.2 kernel, while it seems to work with vanilla 3.7. I am interested in some kind of compatibility matrix having various kernels (pvops0, xenified, with versions) on one axis and Xen releases on the other axis. Also having some info about reasons for breakage-by-design would be helpful. b) is there some doc/info on what is going on with blktap[1,2,3]? I am specifically interested in underlying (design) questions, for example why blktap was not migrated to vanilla kernel 3.x? Regards Andreas
