Description

As suggested by @favogt, the .xml file can be used from a mounted drive instead of modifying the whole ISO. This would simplify the process a lot, as there won't be need to edit the ISO file every time a new version is released.

This can be done by mounting an additional CDROM drive with an ISO containing the Autounattend.xml file. The next command shall be used to generate the ISO properly:

mkisofs -J -graft-points -o autounattend_uefi.iso Autounattend.xml=Autounattend_UEFI.xml

Take into account that the language of the downloaded ISO has to match the one specified in the xml file. In our case it should be en-US, not international en-GB.

For adding a third CD drive it's been necessary to switch CDMODEL variable from ide-cd to scsi-cd. This revealed that the virtio drivers need to be updated to add the scsi ones, as the installation is not getting the drivers if so. The drivers are placed under vioscsi\....

There are plenty of issues trying to address more than two CDROM in scsi format, so I'm trying to use the two usual disks used for Windows ISO and VirtIO drivers, and then add a third one with a autounattend_<bios/uefi>.raw image. The disk can be added with: HDD_2=autounattend_bios.raw HDDMODEL_2=usb-storage,removable=true NUMDISKS=2.

There's no way of making this work by now. I'd focus on fixing the current installation for 24H2 as stated in #176097 and then I'd come back to improving this process.

Why? The HDD_2=autounattend_bios.raw HDDMODEL_2=usb-storage,removable=true NUMDISKS=2 works fine here.

Well, finally and with @favogt's help, I've managed to run the tests by attaching the autounattend_<mode>.raw as an external USB drive. Here are some examples:

I think it works but you just don't see anything. You might have to either set QEMU_VIDEO_DEVICE=ramfb or use both ramfb + virtio-gpu-pci and switch between them.

BTW, you don't want to run the installation with software emulation, that's way too slow. So far I used HW emulation for installation and only used TCG for WSL2 if necessary.
