Ubuntu's  10.10  2.6.35-22-generic (or server)  works fine for PV DomUs sharing
same image device. I never tested  vanilla 2.6.35 (36) itself for PV DomU support.

I know that. I was asking what version worked for you in the past. As in, did you do
the same tests with older kernels (2.6.36 for example?)
