kvm does not virtualize a PMU before Linux 3.3, so oprofile is not supported. The facilities for identifying the PMU to the guest are very lacking, so it's hard to make this fail gracefully.
On a Linux 3.3 host, you can provide a PMU to the guest, but only using latest qemu and providing -cpu host or similar. This only works on Intel hosts for now.
