Hi, I am trying to count instructions executed for programs running in an 11.0 guest OS (Virtual Box is the hypervisor). However, pwstat is reporting obviously low numbers. Firefox, for example, is reporting ~7000 instructions when executing the Kraken benchmark. I've installed the emulator/virtualbox-ose-additions package, as well as put vboxguest_enable="YES" and vboxservice_enable="YES" in my /etc/rc.conf. After executing kldload hwpmc, dmesg reports hwpc_core: unknown PMC architecture: 0. Any ideas as to what could be the problem?
