PAPI Forum

Hi I am running Papi 4.1.3 on an Ubuntu 11 virtual machine. I can run configure and make, but it fails on the make test portion. What is the issue? And can I even use PAPI inside of a VM?

Here is the error:

Please advise.

Most virtual hypervisors don't expose the hardware counters, so even though PAPI appropriately identifies the virtual cpu and looks like it builds correctly, it cannot access the counters. So unfortunately, for now PAPI won't run in a virtual environment. What virtual system are you using?

Oh, I see. Thank you!!

I am using Ubuntu 11 in Oracle VirtualBox.
