I am running the latest xen-unstable on linux 2.6.16.13. I get the following errors on trying to start Oprofile in the guest

Operation 8 failed for domid 1 (sattus=-1). Could not open profiled device

And operation 8 in xenoprof.h is enable_virq.

I have debugged a bit and found that the active_index is returning -1 for the guest domid.

Renato suggests debugging the XENOPROF hypercall set_active as it may not be adding the domain to the active list.

Quick sanity check: what's the contents of /dev/oprofile/active_domains on your primary domain?
