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.

git branch for testing (including updated seabios):
	https://git.kraxel.org/cgit/qemu/log/?h=sirius/microvm

changes in v2:
  * some acpi cleanups are an separate patch series now.
  * switched to hw reduced acpi & generic event device.
  * misc fixes here and there.

changes in v3:
  * depeds on "[PATCH v6 00/16] acpi: i386 tweaks" series.
  * renamed qboot to qboot.bin
  * updated seabios to master branch snapshot.
    - this version boots fine with rtc=off
  * generic event device tweaks (Igor's comments).
  * make SMP work.
  * add RfC patches to turn off acpi by default for microvm.
  * misc fixes here and there.

changes in v4
  * rebase to latest master
    - this also depends on the pending seabios update
  * drop some patches which got cherry-picked.
  * wire up cpu hotplug (also does coldplug cpu init).
  * add microvm acpi test case.
  * dropped RfC patches to turn off acpi by default for microvm.
  * misc fixes here and there.

take care,
  Gerd
