Hi Sergio, Paolo,

microvm is a machine type inspired by Firecracker and constructed
after its machine model.
It's a minimalist machine type without PCI nor ACPI support, designed
for short-lived guests. microvm also establishes a baseline for
benchmarking and optimizing both QEMU and guest operating systems,
since it is optimized for both boot time and footprint.

Do we want to maintain a 32-bit microvm?
IIUC the main interest in 64-bit.
Can we restrict it with this change?
