Note that only a RPi-4 will provide any sort of performance, assuming
the OP wants to use KVM as the acceleration backend.

The original RPi has no support for virtualisation (ARM 1176), and
the two following models are deprived of a GIC, making them a bit
useless (we have *some* support code in KVM, but I'm pretty sure it
has bitrot by now).
