[Xen-users] VM performance counters

Hi all,

I'm trying to find a way to get performance counters per VM, like perf does for 
the kernel. At least I should be able to get the instruction and memory access 
count (or IPC/MPC).
I've looked in the sched_credit.c source for any pointers, and indeed it 
mentions something called a 'runq dump', yet I've got no idea what that might 
If possible, I'd like to access this in dom0 without any modifications to Xen 
and/or the kernel -- I'm not very familiar with patching let alone modifying 
low level code by myself.

Any help would be appreciated,
