[PATCH v9 00/15] Introduce the microvm machine type
Posted by Sergio Lopez 4 years, 5 months ago
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).
