I've updated the wiki. Being open-source, in theory someone could
contribute PMU virtualization to VirtualBox to make it work.

VMWare is effectively free with VMWare Player. Despite the name, you can
create VMs as well as run them: "VMware Workstation Player provides a
streamlined user interface for creating, running and evaluating operating
systems and applications in a virtual machine on Windows or Linux PCs." In
theory it's a 30-day trial but I guess you can just reinstall it.
