[PATCH 00/13] microvm: add acpi support

[Gerd Hoffmann]

I know that not supporting ACPI in microvm is intentional.  If you still
don't want ACPI this is perfectly fine, you can use the usual -no-acpi
switch to toggle ACPI support.

These are the advantages you are going to loose then:

  (1) virtio-mmio device discovery without command line hacks (tweaking
      the command line is a problem when not using direct kernel boot).
  (2) Better IO-APIC support, we can use IRQ lines 16-23.
  (3) ACPI power button (aka powerdown request) works.
  (4) machine poweroff (aka S5 state) works.

Together with seabios patches for virtio-mmio support this allows to
boot standard fedora images (cloud, coreos, workstation live) with the
microvm machine type.

cheers,
  Gerd
