Introduce the microvm machine type
v9 cover Introduce the microvm machine type
Microvm is a machine type inspired by Firecracker and constructed after the 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.

Changelog
v9:
- Fix a typo in "[PATCH v9 05/15] hw/i386/pc: avoid an assignment in if condition in x86_load_linux()" (Philippe Mathieu-Daudé)
- Replace qemu_strtol() with qemu_strtoui() to preserve the original type of video_mode (Philippe Mathieu-Daudé)
v8:
- Split "[PATCH v7 03/12] hw/i386/pc: fix code style issues on functions that will be moved out" into four different patches (Philippe Mathieu-Daudé)
v7:
- Fix code style issues on already present code touched by this patch series (Michael S. Tsirkin, Philippe Mathieu-Daudé)
- Add new files to MAINTAINERS (Michael S. Tsirkin, Philippe Mathieu-Daudé)
- Allow starting a microvm machine without a kernel image, fixing "qom-test" (Michael S. Tsirkin)
- Change "bios-microvm.bin" mode to 0644 (Stefano Garzarella)
- Remove unneeded "hw/i386/pc.h" include from x86.c (Stefano Garzarella)
v6:
- Some style fixes (Philippe Mathieu-Daudé)
- Fix a documentation bug stating that LAPIC was in userspace (Paolo Bonzini)
- Update Xen HVM code after X86MachineState introduction (Philippe Mathieu-Daudé)
- Rename header guard from QEMU_VIRTIO_MMIO_H to HW_VIRTIO_MMIO_H (Philippe Mathieu-Daudé)
v5:
- Drop unneeded "[PATCH v4 2/8] hw/i386: Factorize e820 related functions" (Philippe Mathieu-Daudé)
- Drop unneeded "[PATCH v4 1/8] hw/i386: Factorize PVH related functions" (Stefano Garzarella)
- Split X86MachineState introduction into smaller patches (Philippe Mathieu-Daudé)
- Change option-roms to x-option-roms and kernel-cmdline to auto-kernel-cmdline (Paolo Bonzini)
- Make i8259 PIT and i8254 PIC optional (Paolo Bonzini)
- Some fixes to the documentation (Paolo Bonzini)
- Switch documentation format from txt to rst (Peter Maydell)
- Move NMI interface to X86_MACHINE (Philippe Mathieu-Daudé, Paolo Bonzini)
v4:
- This is a complete rewrite of the whole patchset, with a focus on reusing as much existing code as possible to ease the maintenance burden and making the machine type as compatible as possible by default. As a result, the number of lines dedicated specifically to microvm is 383 (code lines measured by "cloc") and, with the default configuration, it's now able to boot both PVH ELF images and bzImages with either SeaBIOS or qboot.
v3:
- Add initrd support (thanks Stefano).
v2:
- Drop "[PATCH 1/4] hw/i386: Factorize CPU routine".
- Simplify machine definition (thanks Eduardo).
- Remove use of unneeded NUMA-related callbacks (thanks Eduardo).
- Add a patch to factorize PVH-related functions.
- Replace use of Linux's Zero Page with PVH (thanks Maran and Paolo).

PATCH v9 2/15 hw/i386/pc: rename functions shared with non-PC machines
In reply to Sergio LopezThe following functions are named *pc* but are not PC-machine specific but generic to the X86 architecture, rename them:
load_linux -> x86_load_linux pc_new_cpu -> x86_new_cpu pc_cpus_init -> x86_cpus_init pc_cpu_index_to_props -> x86_cpu_index_to_props
pc_get_default_cpu_node_id -> x86_get_default_cpu_node_id
pc_possible_cpu_arch_ids -> x86_possible_cpu_arch_ids
old_pc_system_rom_init -> x86_system_rom_init

I'm wondering if using fprintf() is appropriate, thinking about instantiating a machine via libvirt, is this error reported to the user?
I first thought about using error_report() instead:
error_report("qemu: can't parse 'vga' parameter: %s",
strerror(-ret));
But this API is meaningful when used in console/monitor. We can't get here from the monitor, so:

In reply to Sergio LopezAs a last step into splitting PCMachineState and deriving X86MachineState from it, make the functions previously extracted from pc.c to x86.c independent from PCMachineState, using X86MachineState instead.

PATCH v9 12/15 roms: add microvm-bios (qboot) as binary and git submodule
In reply to Sergio Lopezqboot is a minimalist x86 firmware for booting Linux kernels. It does the mininum amount of work required for the task, and it's able to boot both PVH images and bzImages without relying on option roms.
This characteristics make it an ideal companion for the microvm machine type.

PATCH v9 14/15 hw/i386: Introduce the microvm machine type
In reply to Sergio LopezMicrovm is a machine type inspired by Firecracker and constructed after the 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.

Per the documentation, you are correct:
Boards specify their constituent devices using ``imply`` and ``select`` directives. A device should be listed under ``select`` if the board cannot be started at all without it. It should be listed under ``imply`` if (depending on the QEMU command line) the board may or may not be started without it. Boards also default to false; they are enabled by the ``default-configs/*.mak`` for the target they apply to.
But then the build fails configured with --without-default-devices:

The ifdef'ery is okay in board code, but in this case I think it would be even better to have a stub for serial_hds_isa_init that gives the right error (via Error*, and then you can call it with &error_fatal etc.). So for now I included your patch that changes it to "select" from the other series.
