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.
