Actually, removing PCI (and ACPI), is one of the main ways microvm has
to reduce not only boot time, but also the exposed surface and the
general footprint.
I think we need to discuss and settle whether using virtio-mmio (even if
maintained and upgraded to virtio 1) for a new machine type is
acceptable or not. Because if it isn't, we should probably just ditch
the whole microvm idea and move to something else.
Sergio.
