No, this is completely independent of blktap. Currently, PV machines
just don't have a virtual cpu in qemu - in contrary to FV machines which
call a complete pc_machine.init() during their initialization.
Maybe you're right and it would be better to assign even PV machines a
cpu, but I'm not sure what other functionality this implies to
implement. I'll try to look into this.
