libvirt & qemu are supported on macos (https://libvirt.org/platforms.html) &
can use PMU
(https://stackoverflow.com/questions/46490857/how-to-enable-pmu-in-kvm-guest)
You can use homebrew to install libvirt & qemu
brew install libvirt qemu
virt-manager & virt-viewer (https://virt-manager.org/) are GUI tools
create/manage/view KVM virtual machines. Macos support and install
instructions are here:
https://github.com/jeffreywildman/homebrew-virt-manager
Or instead of virt-manager you can just use the command line and then
install VNC on the vm:
