[Xen-users] Xenoprof (0.9.5) in PVOPS

["Chulmin Kim" <cmkim@xxxxxxxxxxxxxxxx>]

Hi All.

 

I’m trying to use xenoprof in my Xeon machine with PVOPS (3.1.0 kernel) & xen 4.1.1.

 

In the past, I had failed to use the xenoprof in this environment. (1 year ago)

 

While baremetal booting shows the counter object in /dev/oprofile/0 (or 1,2,3) ,

booting with xen fails to create those objects.

 

Of course, opcontrol command doesn’t work. It only prints out that error : counter 0 unavailable…

 

I’ve searched the web, but I couldn’t get the enough info to resolve it.

 

Is there anyone who knows about this issue?

 

Thanks!
