No the PV drivers aren't for PV domUs, those have their storage/network
already PV virtualized. The HVM virtualization is only virtualizing CPU
and RAM storage/network needs to be emulated (using Qemu btw.) which is
slow. PV drivers allow HVM domUs to connect to backend driver services
running in Dom0.
