[edk2-devel] [PATCH 00/17] [RFC] OvmfPkg: Add support for microvm machine type

[Yao, Jiewen]

Hi Gerd
I would like to confirm a couple of things:

-1) Since this is a big new feature, please follow process to submit Bugzilla.

0) I hope we can include a readme file to introduce more background and the scope of the new project.

1) What is the device list of microvm? Or do you mean https://qemu.readthedocs.io/en/latest/system/i386/microvm.html?

2) How many QEMU configurations do we want to support ? Do we need support all described in https://qemu.readthedocs.io/en/latest/system/i386/microvm.html?

3) What is the reason to add a new dsc/fdf instead of add a MACRO/PCD in OVMF?
