One of the problems is that some VCPU initialization hypercalls at the
moment are PV specific and don't work with HVM guests, in particular I
find that VCPUOP_initialise doesn't work correctly for me.
But the timers shouldn't be an issue because you should be able to
receive the VIRQ_TIMER or the emulated timer interrupt anyway.
