I think there is a difference between the two kernels. The pvops kernel
goes into state 2 right away (I cant tell from repeated xenstore-ls runs
if it had also state 1).
The sles11 kernel remains in state 1. Did the expectations of libxl
change recently? xl create used to work not too long ago.

xm does not work either, so the change is most likely in the scripts.
