Xenperf seems to be broken with the 2.6.16.29 kernel.
All the counters just show 0. I checked the 2.6.16.13 version and the current one and there seem to be quite a few changes
 
Example XEN_SYSCTL_PERFCOP_query replaces DOM0_PERFCCONTROL_OP_QUERY
 
Can someone please let me know how I can get it working again?

It may need some debugging. Noone may have tried using it since the change to domctl/sysctl.
